GENERAL POWER TOOL SAFETY WARNINGS

WARNING: Read all safety warnings, instructions, illustrations, and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire, and/or serious injury.
SAVE ALL WARNINGS AND INSTRUCTIONS FOR FUTURE REFERENCE.
The term “power tool” in the warnings refers to your mains‑operated (corded) power tool or battery‑operated (cordless) power tool.

1. Work Area Safety
   a ) Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
   b ) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks that may ignite dust or fumes.
   c ) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2. Electrical Safety
   a ) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce the risk of electric shock.
   b ) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is
   earthed or grounded.
   c ) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
   d ) Do not abuse the cord. Never use the cord for carrying, pulling, or unplugging the power tool. Keep the cord away from heat, oil, sharp edges, or moving parts. Damaged or entangled cords increase the risk of electric shock.
   e ) When operating a power tool outdoors, use an extension cord suitable for outdoor use. The use of a cord suitable for outdoor use reduces the risk of electric shock.
   f ) If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. The use of a GFCI reduces the risk of electric shock.

3. Personal Safety
   a ) Stay alert, watch what you are doing, and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.
   b ) Use personal protective equipment. Always wear eye protection. Protective equipment such as a dust mask, non‑skid safety shoes, hard hats, or hearing protection used for appropriate conditions will reduce personal injuries.
   c ) Prevent unintentional starting. Ensure the switch is in the off‑position before connecting to a power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
   d ) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
   e ) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
   f ) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving parts.
   g ) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. The use of dust collection can reduce dust‑related hazards.
   h ) Do not let familiarity gained from the frequent use of tools allow you to become complacent and ignore tool safety principles. A careless action can cause severe injury within a fraction of a second.

4. Power Tool Use and Care
   a ) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
   b ) Do not use the power tool if the switch does not turn on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
   c ) Disconnect the plug from the power source and/or remove the battery pack, if detachable, from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
   d ) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
   e ) Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
   f ) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   g ) Use the power tool, accessories and tool bits, etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
   h ) Keep handles and grasping surfaces dry, clean, and free from oil and grease. Slippery handles and grasping surfaces do not allow for safe handling and control of the tool in unexpected situations.

5. Battery Tool Use and Care
   a ) Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery pack.
   b ) Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
   c ) When the battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws, or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.
   d ) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts the eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
   e ) Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may exhibit unpredictable behavior resulting in fire, explosion, or risk of injury.
   f ) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 265 °F (130 °C) may cause an explosion.
   g ) Follow all charging instructions and do not charge the battery pack or tool outside the temperature range specified in the instructions. Charging improperly or at temperatures outside the specified range may damage the battery and increase the risk of fire.

6. Service
   a ) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.
   b ) Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

Safety Instructions for Miter Saws
a ) Miter saws are intended to cut wood or wood‑like products, they cannot be used with abrasive cut‑off wheels for cutting ferrous material such as bars, rods, studs, etc. Abrasive dust causes moving parts such as the lower guard to jam. Sparks from abrasive cutting will burn the lower guard, the kerf insert and other plastic parts.
b ) Use clamps to support the workpiece whenever possible. If supporting the workpiece by hand, you must always keep your hand at least 4″ (100 mm) from either side of the saw blade. Do not use this saw to cut pieces that are too small to be securely clamped or held by hand. If your hand is placed too close to the saw blade, there is an increased risk of injury from blade contact.
c ) The workpiece must be stationary and clamped or held against both the fence and the table. Do not feed the workpiece into the blade or cut “freehand” in any way. Unrestrained or moving workpieces could be thrown at high speeds, causing injury.
d ) Push the saw through the workpiece. Do not pull the saw through the workpiece. To make a cut, raise the saw head and pull it out over the workpiece without cutting, start the motor, press the saw head down and push the saw through the workpiece. Cutting on the pull stroke is likely to cause the saw blade to climb on top of the workpiece and violently throw the blade assembly toward the operator.
e ) Never cross your hand over the intended line of cutting either in front or behind the saw blade. Supporting the workpiece “cross handed” i.e. holding the workpiece to the right of the saw blade with your left hand or vice versa is very dangerous.
f ) Do not reach behind the fence with either hand closer than 4″ (100 mm) from either side of the saw blade, to remove wood scraps, or for any other reason while the blade is spinning. The proximity of the spinning saw blade to your hand may not be obvious and you may be seriously injured.
g ) Inspect your workpiece before cutting. If the workpiece is bowed or warped, clamp it with the outside bowed face toward the fence. Always make certain that there is no gap between the workpiece, fence, and table along the line of the cut. Bent or warped workpieces can twist or shift and may cause binding on the spinning saw blade while cutting. There should be no nails or foreign objects in the workpiece.
h ) Do not use the saw until the table is clear of all tools, wood scraps, etc., except for the workpiece. Small debris or loose pieces of wood or other objects that contact the revolving blade can be thrown at high speed.
i ) Cut only one workpiece at a time. Stacked multiple workpieces cannot be adequately clamped or braced and may bind on the blade or shift during cutting.
j ) Ensure the miter saw is mounted or placed on a level, firm work surface before use. A level and firm work surface reduce the risk of the miter saw becoming unstable.
k ) Plan your work. Every time you change the bevel or miter angle setting, make sure the fence will not interfere with the blade or the guarding system. Without turning the tool “ON” and with no workpiece on the table, move the saw blade through a complete simulated cut to assure there will be no interference or danger of cutting the fence.
l ) Provide adequate support such as table extensions, saw horses, etc. for a workpiece that is wider or longer than the tabletop. Workpieces longer or wider than the miter saw table can tip if not securely supported. If the cut‑off piece or workpiece tips, it can lift the lower guard or be thrown by the spinning blade.
m ) Do not use another person as a substitute for a table extension or as additional support. Unstable support for the workpiece can cause the blade to bind or the workpiece to shift during the cutting operation pulling you and the helper into the spinning blade.
n ) The cut‑off piece must not be jammed or pressed by any means against the spinning saw blade. If confined, i.e. using length stops, the cut‑off piece could get wedged against the blade and thrown violently.
o ) Always use a clamp or a fixture designed to properly support round material such as rods or tubing. Rods have a tendency to roll while being cut, causing the blade to “bite” and pull the work with your hand into the blade.
p ) Let the blade reach full speed before contacting the workpiece. This will reduce the risk of the workpiece being thrown.
q ) If the workpiece or blade becomes jammed, turn the miter saw off. Wait for all moving parts to stop and disconnect the plug from the power source and/or remove the battery pack. Then work to free the jammed material. Continued sawing with a jammed workpiece could cause loss of control or damage to the miter saw.
r ) After finishing the cut, release the switch, hold the saw head down and wait for the blade to stop before removing the cut‑off piece. Reaching with your hand near the coasting blade is dangerous.
s ) Hold the handle firmly when making an incomplete cut or when releasing the switch before the saw head is completely in the down position. The braking action of the saw may cause the saw head to be suddenly pulled downward, causing a risk of injury.
Additional Safety Rules for Miter Saws
WARNING: Do not allow familiarity (gained from frequent use of your saw) to replace safety rules. Always remember that a careless fraction of a second is sufficient to inflict severe injury.
WARNING: Never modify the power tool or any part of it. Damage or personal injury could result.

• DO NOT OPERATE THIS MACHINE until it is completely assembled and installed according to the instructions. A machine incorrectly assembled can cause serious injury.
• OBTAIN ADVICE from your supervisor, instructor, or another qualified person if you are not thoroughly familiar with the operation of this machine. Knowledge is safety.
• MAKE CERTAIN the blade rotates in the correct direction. The teeth on the blade should point in the direction of rotation as marked on the saw.
• TIGHTEN ALL CLAMP HANDLES, knobs, and levers prior to operation. Loose clamps can cause parts or the workpiece to be thrown at high speeds.
• BE SURE all blade and blade clamps are clean, the recessed sides of blade clamps are against the blade, and the arbor screw is tightened securely. Loose or improper blade clamping may result in damage to the saw and possible personal injury.
• DO NOT OPERATE ON ANYTHING OTHER THAN THE DESIGNATED VOLTAGE for the saw. Overheating, damage to the tool and personal injury may occur.
• DO NOT WEDGE ANYTHING AGAINST THE FAN to hold the motor shaft. Damage to the tool and possible personal injury may occur.
• NEVER CUT FERROUS METALS or masonry. Either of these can cause the carbide tips to fly off the blade at high speeds causing serious injury.
• NEVER PLACE HANDS CLOSER THAN 4″ (100 mm) FROM THE BLADE.
• NEVER HAVE ANY PART OF YOUR BODY IN LINE WITH THE PATH OF THE SAW BLADE. Personal injury will occur.
• NEVER APPLY BLADE LUBRICANT TO A RUNNING BLADE. Applying lubricant could cause your hand to move into the blade resulting in serious injury.

   NOTE: To remove the battery pack, some chargers require the battery pack release button to be pressed.

Hot/Cold Pack Delay
When the charger detects a battery pack that is too hot or too cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the battery pack has reached an appropriate temperature. The charger then automatically switches to the pack charging mode. This feature ensures maximum battery pack life.
A cold battery pack may charge at a slower rate than a warm battery pack.
The hot/cold pack delay will be indicated by the red light(s) continuing to blink but with the yellow light continuously ON. Once the battery pack has reached an appropriate temperature, the yellow light will turn OFF and the charger will resume the charging procedure.
DCB118 and DCB1112 Chargers
The DCB118 and DCB1112 chargers are equipped with an internal fan designed to cool the battery pack. The fan will turn on automatically when the battery pack needs to be cooled.
Never operate the charger if the fan does not operate properly or if ventilation slots are blocked. Do not permit foreign objects to enter the interior of the charger.
Electronic Protection System
Li‑Ion tools are designed with an Electronic Protection System that will protect the battery pack against overloading, overheating, or deep discharge. The tool will automatically turn off and the battery pack will need to be recharged.
Important Charging Notes

1. The longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 65 °F – 75 °F (18 ° C– 24 °C). DO NOT charge when the battery pack is below +40 °F (+4.5 °C), or above +104 °F (+40 °C). This is important and will prevent serious damage to the battery pack.

2. The charger and battery pack may become warm to the touch while charging. This is a normal condition and does not indicate a problem. To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed or an uninsulated trailer.

3. If the battery pack does not charge properly:
   a. Check the operation of the receptacle by plugging in a lamp or other appliance;
   b. Check to see if the receptacle is connected to a light switch which turns the power off when you turn out the lights;
   c. If charging problems persist, take the tool, battery pack, and charger to your local service center.

4. You may charge a partially used pack whenever you desire with no adverse effect on the battery pack.

Charger Cleaning Instructions
WARNING: Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non‑metallic brush. Do not use water or any cleaning solutions.

Wall Mounting
Some DeWALT chargers are designed to be wall mountable or to sit upright on a table or work surface.  If wall mounting, locate the charger within reach of an electrical outlet, and away from a corner or other obstructions which may impede airflow. Use the back of the charger as a template for the location of the mounting screws on the wall. Mount the charger securely using drywall screws (purchased separately) at least 1” (25.4 mm) long, with a screw head diameter of 0.28–0.35” (7–9 mm), screwed into wood to an optimal depth leaving approximately 7/32” (5.5 mm) of the screw exposed. Align the slots on the back of the charger with the exposed screws and fully engage them in the slots.

ASSEMBLY AND ADJUSTMENTS

WARNING: To reduce the risk of serious personal injury, turn the tool off, and remove the battery pack before transporting, making any adjustments, cleaning, repairing, or removing/installing attachments or accessories. An accidental start‑up can cause injury.
NOTE: Your miter saw is fully and accurately adjusted at the factory at the time of manufacture. If readjustment due to shipping and handling or any other reason is required, follow the steps below to adjust your saw.

Familiarization (Fig. A, D)
Your miter saw is not fully assembled in the carton. Refer to Assembling the Base Extensions and Assembling the Stabilizer Bar sections for assembly instructions. Open the box and lift the saw out by the convenient lifting handle 15, as shown in Figure D.
Place the saw on a smooth, flat surface such as a workbench or strong table.
Examine Figure A to become familiar with the saw and its various parts. The section on adjustments will refer to these terms and you must know what and where the parts are.
CAUTION: Pinch Hazard. To reduce the risk of injury, keep thumb underneath the handle when pulling the handle down. The lower guard will move up as the handle is pulled down which could cause pinching. The handle is placed close to the guard for special cuts.
Press down lightly on the operating handle 2 and pull the head lock knob 19   and rotate 90 degrees. Gently release the downward pressure and hold the arm allowing it to rise to its full height. Use the head lock knob when carrying the saw from one place to another. Always use the lifting handle 15 to transport the saw or the hand indentations 11   shown in Figure A.
Use of CUTLINE™ LED Worklight (Fig. A)
CAUTION: Do not stare into work right. Serious eye injury could result.
NOTE: The battery must be charged and connected to the miter saw.
The CUTLINE™ LED Worklight can be turned on by the momentary switch   21. The light will automatically turn off within 20 seconds if the saw is not in use. The light is also activated automatically every time the tool’s main trigger 1 is pulled.
To cut through an existing pencil line on a piece of wood, turn on the CUTLINE™ work light using the momentary switch 21 (not with the main trigger), then pull down on the operating handle 2 to bring the saw blade close to the wood. The shadow of the blade will appear on the wood. This shadow line represents the material that the blade will remove when performing a cut. To correctly locate your cut to the pencil line, align the pencil line with the edge of the blade’s shadow. Keep in mind that you may have to adjust the miter or bevel angles in order to match the pencil line exactly.
Your saw is equipped with a battery monitoring feature. The CUTLINE™ work light begins to flash when the battery is near the end of its useful charge and/or when the battery is too hot. Charge the battery prior to continuing cutting applications. Refer to the Charging Procedure under Important Safety Instructions for All Battery Chargers for battery charging instructions.
Miter Control (Fig. A)
The miter lock lever and miter detent latch allow you to miter your saw to 60 ° right and 50° left. To miter the saw, lift the miter lock handle 7 , squeeze the miter detent latch 8 and move the miter arm to the angle desired on the miter scale 9 as shown at the miter scale pointer 31. Push down on the miter lock lever to lock the miter arm in place.
Assembling the Base Extensions (Fig. E)
WARNING: Base extensions must be assembled on both sides of the saw’s base before using the saw.

1. Extension  32  should be oriented as shown in Figure E, sliding fully into the U‑shaped supports.
2. Clamp the extension’s rods against the miter saw base by inserting the extension screw  63 entirely through the clamp.
3. Repeat steps 1 through 3 on the other side.

Bench Mounting (Fig. A)
Mounting holes 5 are provided in all 4 feet to facilitate bench mounting, as shown in Figure A. (Two different‑sized holes are provided to accommodate different sizes of screws. Use either hole, it is not necessary to use both.) Always mount your saw firmly to a stable surface to prevent movement. To enhance the tool’s portability, it can be mounted to a piece of 1/2” (12.7 mm) or thicker plywood which can then be clamped to your work support or moved to other job sites and reclamped.
NOTE: If you elect to mount your saw to a piece of plywood, make sure that the mounting screws don’t protrude from the bottom of the wood. The plywood must sit flush on the work support. When clamping the saw to any work surface, clamp only on the clamping bosses where the mounting screw holes are located. Clamping at any other point will surely interfere with the proper operation of the saw.
CAUTION: To prevent binding and inaccuracy, be sure the mounting surface is not warped or otherwise uneven. If the saw rocks on the surface place a thin piece of material under one saw foot until the saw sits firmly on the mounting surface.
Assembling the Stabilizer Bar (Fig. F)
Your saw includes one base stabilizer 14 This must be installed before using your saw. Insert the stabilizer into the holes in the back of the unit. Move the stabilizer in or out until it contacts the work surface. Then tighten the screws 62 in the base to fasten the stabilizer.

Changing or Installing a New Saw Blade (Fig. A, G)

WARNING: To reduce the risk of serious personal injury, turn the tool off, and remove the battery pack before transporting, making any adjustments, cleaning, repairing, or removing/installing attachments or accessories. An accidental start‑up can cause injury.
CAUTION:

• Never depress the spindle lock button while the blade is under power or coasting.
• Do not cut ferrous metal (containing iron or steel) or masonry or fiber cement products with this miter saw.

Removing the Blade (Fig. A, G)

1. Remove battery pack 3 from the saw.
2. Raise the arm to the upper position and raise the lower guard 6 as far as possible.
3. Depress the spindle lock button 36 while carefully rotating the saw blade by hand until the lock engages.
4. Using your finger, pivot the blade bolt plate 38 to gain access to the blade bolt head 40.
5. Keeping the spindle lock button depressed and the blade bolt plate pushed out of the way, use the blade wrench 37 provided to loosen the blade screw. (Turn clockwise, left‑hand threads.) Remove the blade screw.
6. Proceed to remove the outer clamp washer, blade adaptor, and saw blade.

Installing a Blade (Fig. A, G)

1. Remove battery pack 3 from the saw.
2. Raise the saw head to the upper position and raise the lower guard 6 as far as possible. Place blade 39 on the spindle, followed by blade adaptor 57 then outer clamp washer 56. Make sure to match the arrow direction on the blade with the arrow direction on the guard plate.
3. Depress the spindle lock button 36 while carefully rotating the saw blade by hand until the lock engages.
4. Using your finger, push back the blade bolt plate 38 to gain access to blade bolt head 40.
5. Keeping the spindle lock button depressed and the blade bolt plate pushed out of the way, use the blade wrench 37 provided to firmly tighten the blade screw. (Turn counter‑clockwise, left‑hand threads.)

Miter Scale Adjustment (Fig. A, H)
Unlock the miter lock handle 7 and swing the miter arm until the miter latch 8  locks it at the 0 ° miter position. Do not lock the miter lock handle. Place a square against the saw’s fence and blade, as shown. (Do not touch the tips of the blade teeth with the square. To do so will cause an inaccurate measurement.) If the saw blade is not exactly perpendicular to the fence  12, loosen the four miter scale screws  10  that hold the miter scale and move the miter lock handle and the scale left or right until the blade is perpendicular to the fence, as measured with the square. Retighten the four screws. Pay no attention to the reading of the miter pointer at this time.
Miter Pointer Adjustment (Fig. A)
Unlock the miter lock handle  7  to move the miter arm to the zero position. With the miter lock handle unlocked, squeeze the miter detent latch  8  and allow the miter latch to snap into place as you rotate the miter arm to zero. Observe the miter pointer  31  and miter scale  9  shown in Figure A. If the pointer does not indicate exactly zero, loosen the miter pointer screw  27 holding the pointer in place, reposition the pointer and tighten the screw.
Bevel Square to Table (Fig. A, I, J)
To align the blade square to table  18, lock the arm in the down position with the lockdown pin  19. Place a square against the blade, ensuring the square is not on top of a tooth.  Loosen the bevel lock knob  13  and ensure the arm is firmly against the 0 ° bevel stop. Rotate the 0 ° bevel adjustment screw  42 with the 1/2” blade wrench as necessary so that the blade is at 0 ° bevel to the table.
Bevel Pointer (Fig. J)
If the bevel pointer  43  does not indicate zero, loosen the screw  44  that holds it in place and move the pointer as necessary. Ensure the 0 ° bevel is correct and the bevel pointers are set before adjusting any other bevel angle screws.
Adjusting the Bevel Stop to 45 ° Left or Right (Fig. A, J)
To adjust the right 45 ° bevel angle, loosen the bevel lock knob  13  and pull the 0 ° bevel stop, rotate 90 ° (either clockwise or counterclockwise), and let go for the spring-loaded pin to lock in to override the 0 ° bevel stops. When the saw is full to the right if the bevel pointer does not indicate exactly 45 °, turn the left 45 ° bevel adjustment screw  45  with the 1/2″ blade wrench until the bevel pointer indicates 45 °.
To adjust the left 45 ° bevel stop, first, loosen the bevel lock knob and tilt the head to the left. If the bevel pointer does not indicate exactly 45 °, turn the right 45 ° bevel adjustment screw 45 until the bevel pointer  43 reads 45 °.
Adjusting the Bevel Stop to 22.5 ° (or 33.9 °) (Fig. A, J)
NOTE: Adjust the bevel angles only after performing the 0 ° bevel angle and bevel pointer adjustment.

• To set the left 22.5 ° bevel angle, flip out the left 22.5 ° bevel pawl  47. Loosen the bevel lock knob  13  and tilt the head fully to the left. If the bevel pointer does not indicate exactly 22.5 °, turn the crown adjustment screw  46  contacting the pawl with a 7/16” wrench until the bevel pointer reads 22.5 °.
• To adjust the right 22.5 ° bevel angle, flip out the right 22.5 ° bevel pawl. Loosen the bevel lock knob and pull the 0 ° bevel stop and rotate 90 degrees to override the 0 ° bevel stop. When the saw is full to the right, if the bevel pointer does not indicate exactly 22.5 °, turn the crown adjustment screw contacting the pawl with a 7/16” wrench until the bevel pointer indicates exactly 22.5 °.

Fence Adjustment (Fig. A)
In order that the saw can bevel to many bevel positions, one of the fences may have to be adjusted to provide clearance. To adjust each fence, loosen the fence adjustment knob  16 and slide the fence outward. Make a dry run with the saw turned off and check for clearance.
Adjust the fence to be as close to the blade as practical to provide maximum workpiece support, without interfering with arm up and down movement. Tighten the fence adjustment knob securely. When the bevel operations are complete, don’t forget to relocate the fence.
For certain cuts, it may be desirable to bring the fences closer to the blade. To use this feature, back the fence adjustment knobs out two turns and move the fences closer to the blade past the normal limit, then tighten the fence adjustment knobs to keep the fences in this location. When using this feature, make a dry cut first to ensure the blade does not contact the fences.
NOTE: The tracks of the fences can become clogged with sawdust. If you notice that they are becoming clogged, use a brush or some low-pressure air to clear the guide grooves.

Guard Actuation and Visibility (Fig. A, Z)

CAUTION: Pinch Hazard. To reduce the risk of injury, keep your thumb underneath the handle when pulling the handle down. The lower guard will move up as the handle is pulled down which could cause pinching.
The lower guard  6  on your saw has been designed to automatically uncover the blade when the arm is brought down and to cover the blade when the arm is raised.
The guard can be raised by hand when installing or removing saw blades or for inspection of the saw. NEVER RAISE THE LOWER GUARD MANUALLY UNLESS THE BLADE IS STOPPED.
NOTE: Certain special cuts of large material will require that you manually raise the guard. Refer to Cutting large Material under Special Cuts.
The front section of the guard is louvered for visibility while cutting. Although the louvers dramatically reduce flying debris, they are openings in the guard, and safety glasses should be worn at all times when viewing through the louvers.
Rail Guide Adjustment (Fig. A, F)
Periodically check the rails  24  for any play or clearance. The right rail can be adjusted with the rail set screw  33  shown in Figure F. To reduce clearance, use a 4 mm hex wrench and rotate the rail set screw clockwise gradually while sliding the saw head back and forth. Reduce play while maintaining minimum slide force.
Miter Lock Adjustment (Fig. A, K)
The miter lock rod  48  should be adjusted if the table of the saw can be moved when the miter lock handle  7  is locked (down). To adjust the miter lock  49, put the miter lock handle in the unlocked (up) position. Using a slotted screwdriver, adjust the lock rod in 1/8 clockwise turn increments to increase the locking force. To ensure the miter lock is functioning properly, re‑lock the miter lock handle to a non‑detent miter angle – for example, 34 ° ‑ and make sure the table will not rotate.

Transporting the Saw (Fig. A)
WARNING: To reduce the risk of serious personal injury, turn the tool off, remove the battery pack, and place the lock lever in the transport position before transporting, making any adjustments, cleaning, repairing, or removing/installing attachments or accessories. An accidental start‑up can cause injury.
WARNING: To reduce the risk of serious personal injury, ALWAYS lock the rail lock knob 30, miter lock handle 7, bevel lock knob 13, head lock knob 19, and fence adjustment knobs  16  before transporting the saw.
In order to conveniently carry the miter saw from place to place, a lifting handle 15  has been included on the top of the saw arm and hand indentations 11 in the base.
Head Lock Knob (Fig. A)
WARNING: The head lock knob should be used ONLY when carrying or storing the saw. NEVER use the headlock knob for any cutting operation.
To lock the saw head in the down position, push the head down, rotate the head lock knob 19 90 ° and the spring loaded pin will lock in and release the saw head. This will hold the saw head safely down for moving the saw from place to place.
To release, press the saw head down, pull out the head lock knob and rotate 90 °.

FEATURES AND CONTROLS

WARNING: To reduce the risk of serious personal injury, turn the tool off, and remove the battery pack before transporting, making any adjustments, cleaning, repairing, or removing/installing attachments or accessories. An accidental start‑up can cause injury.
Bevel Lock Knob (Fig. A)
The bevel lock knob  13  allows you to bevel the saw 49 ° left or right. To adjust the bevel setting, turn the knob counterclockwise. The saw head bevels easily to the left or to the right once the 0 ° bevel stop  28  is in the 0 ° bevel override position. To tighten, turn the bevel lock knob clockwise.
0 ° Bevel Override (Fig. A)
The bevel stop override allows you to bevel the saw to the right past the 0 ° mark. When engaged, the saw will automatically stop at 0 ° when brought up from the left.
To move past 0 ° to the right, pull the 0 ° bevel stop  28, rotate 90 ° (either clockwise or counterclockwise), and let go for the spring-loaded pin to lock in.
To return the bevel to 0 ° bevel stop, pull the 0 ° bevel stop, rotate 90 ° (either clockwise or counterclockwise), and let go for the spring-loaded pin will lock in.
45 ° Bevel Stop Override (Fig. J)
There are two bevel stop override levers  50, one on each side of the saw. To bevel the saw, left or right, past 45 °, push the 45 ° bevel to override the lever rearward. When in the rearward position, the saw can bevel past these stops. When the 45 ° stops are needed, pull the 45 ° bevel override lever forward.
Crown Bevel Pawls (Fig. J)
When cutting crown molding laying flat, your saw is equipped to accurately and rapidly set a crown stop, left or right (refer to Instructions for Cutting Crown Molding Laying Flat and Using the Compound Features). The crown bevel pawl  51  can be rotated to contact the crown adjustment screw  46. The saw is factory set to be used for the typical crown in North America (52/38) but can be reversed to cut non‑typical (45/45) crown. To reverse the crown bevel pawl, remove the retaining screw, the 22.5 ° bevel pawl, and the 33.9 ° crown bevel pawl. Flip the crown bevel pawl so the 30 ° is facing up. Reattach the screw to secure the 22.5 ° bevel pawl and the crown bevel pawl. The accuracy setting will not be affected.
22.5 ° Bevel Pawls (Fig. J)
Your saw is equipped to rapidly and accurately set a 22.5 ° bevel, left or right. The 22.5 ° bevel pawl  47 can be rotated to contact the crown adjustment screw.
Rail Lock Knob (Fig. A)
The rail lock knob  30  allows you to lock the saw head firmly to keep it from sliding on the rails. This is necessary when making certain cuts or when transporting the saw.
Depth Stop (Fig. A)
The depth stop  25  allows the depth of cut of the blade to be limited. The stop is useful for applications such as grooving and tall vertical cuts. Rotate the depth stop forward and adjust the depth adjustment screw  29  to set the desired depth of cut. To secure the adjustment, tighten the wing nut 22. Rotating the depth stop to the rear of the saw will bypass the depth stop feature. If the depth adjustment screw is too tight to loosen by hand, the provided blade wrench can be used to loosen the screw.
Slide Lock Transport Lever (Fig. L1–L3)
slide lock Position (Fig. l1)
The slide lock transport lever  61  in forwarding location locks saw for maximizing vertical cutting capacity.
Transport Position (Fig. l2)
The slide lock transport lever  61  in the rear location locks the saw in the transport position to secure the saw head during transport and storage. Recommended for relocating or carrying the saw.
Stow Position (Fig. l3)
When not in use, the slide lock transport lever  61  can be placed in a stow position. The slide lock lever locks in place using an indent on the back of the lever that slides up the ramp and falls into the cast pocket  64. To unlock the lever, slightly pull the lever till it clears out of the cast pocket and rotates clockwise.
Automatic Electric Brake
Your saw is equipped with an automatic electric blade brake which stops the saw blade within 5 seconds of trigger release. This is not adjustable.
On occasion, there may be a delay after trigger release to break the engagement. On rare occasions, the brake may not engage at all and the blade will coast to a stop.
If a delay or “skipping” occurs, turn the saw on and off 4 or 5 times. If the condition persists, have the tool serviced by an authorized DeWALT service center.
Always be sure the blade has stopped before removing it from the kerf. The brake is not a substitute for guards or for ensuring your own safety by giving the saw your complete attention.

OPERATION

** WARNING: To reduce the risk of serious personal injury, turn the tool off, and remove the battery pack before transporting, making any adjustments, cleaning, repairing, or removing/installing attachments or accessories. An accidental start‑up can cause injury.
WARNING: Always use eye protection. All users and bystanders must wear eye protection that conforms to ANSI Z87.1 (CAN/CSA Z94.3).
WARNING: To ensure the blade path is clear of obstructions, always make a dry run of the cut without power before making any cuts on the workpiece.
Installing and Removing the Battery Pack (Fig. A)
WARNING: Ensure the tool/appliance is in the off position before inserting the battery pack.
NOTE: For best results, make sure your battery pack is fully charged.
To install battery pack  3  into the tool handle, align the battery pack with the rails inside the tool’s handle and slide it into the handle until the battery pack is firmly seated in the tool and ensure that it does not disengage.
To remove the battery pack from the tool, press the release button  4  and firmly pull the battery pack out of the tool handle. Insert it into the charger as described in the charger section of this manual.
Body and Hand Position (Fig. M)
WARNING: To reduce the risk of serious personal injury, ALWAYS use the proper hand position as shown.
WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation of a sudden reaction.
Proper positioning of your body and hands when operating the miter saw will make cutting easier, more accurate, and safer. Never place hands near the cutting area. Place hands no closer than 4″ (100 mm) from the blade. Hold the workpiece tightly to the table and the fence when cutting. Keep hands in position until the trigger has been released and the blade has completely stopped. ALWAYS MAKE DRY RUNS (UNPOWERED) BEFORE FINISHING CUTS SO THAT YOU CAN CHECK THE PATH OF THE BLADE. DO NOT CROSS YOUR ARMS, AS SHOWN IN FIGURE M.
Keep both feet firmly on the floor and maintain proper balance. As you move the miter arm left and right, follow it and stand slightly to the side of the saw blade. Sight through the guard louvers when following a pencil line.
Trigger Switch (Fig. N)
To turn the saw on, push the lock‑off lever  41  to the left, then depress the trigger switch  1. The saw will run while the switch is depressed. Allow the blade to spin up to full operating speed before making the cut. To turn the saw off, release the switch. Allow the blade to stop before raising the saw head. There is no provision for locking the switch on. A hole  52  is provided in the trigger for the insertion of a padlock to lock the switch off.
Always be sure the blade has stopped before removing it from the kerf.
Dust Extraction (Fig. O)
WARNING: To reduce the risk of serious personal injury, turn the tool off, and remove the battery pack before transporting, making any adjustments, cleaning, repairing, or removing/installing attachments or accessories. An accidental start‑up can cause injury.
CAUTION:** Never operate this saw unless the dust bag or DeWALT dust extractor is in place. Wood dust may create a breathing hazard.
Your saw has a built‑in dust port that allows an Airlock™ compatible dust collection system to be connected. Use of a non‑Airlock dust collection system requires the use of the supplied vacuum adapter.
Our recommended optimal solution:

• Vacuum (DXV14P)
• Separator (DXVCS003)
• 2‑½” x 7′ Hose (DXVA19‑2501)
• Vacuum Adapter: Used for DXV series vacuums and other non‑Airlock compatible vacuums.

To Attach the Dust Bag (Fig. P)

1. Fit the dust bag  53  to the dust port  17  as shown in Figure P.

To Empty the Dust Bag (Fig. P)

1. Remove dust bag  53  from the saw and gently shake or tap the dust bag to empty.
2. Reattach the dust bag back onto the dust port  17.

You may notice that all the dust will not come free from the bag. This will not affect cutting performance but will reduce the saw’s dust collection efficiency. To restore your saw’s dust collection efficiency, depress the spring inside the dust bag when you are emptying it and tap it on the side of the trash can or dust receptacle.
Through‑Cutting Operations (Fig. A)
If the slide feature is not used, ensure the saw head is pushed back as far as possible and the rail lock knob is tightened. This will prevent the saw from sliding along its rails as the workpiece is engaged.
NOTE: Although this saw will cut wood and many non‑ferrous materials, we will limit our detailed discussion to the cutting of wood only. The same guidelines apply to the other materials. DO NOT CUT FERROUS (IRON AND STEEL) MAT SERIALS OR MASONRY WITH THIS SAW.Do not use any abrasive blades.
NOTE: Refer to guard Actuation and Visibility in the Adjustments section for important information about the lower guard before cutting.
Crosscuts (Fig. A, Q)
A crosscut is made by cutting wood across the grain at any angle. A straight crosscut is made with the miter arm at the zero-degree position. Set and lock the miter arm at zero, and hold the wood firmly on the table and against the fence. With the rail lock knob tightened, turn on the saw by squeezing the trigger switch  1  shown in Figure A.
When the saw comes up to speed (about 1 second) lower the arm smoothly and slowly to cut through the wood. Let the blade come to a full stop before raising the arm.
When cutting anything larger than a 2 x 8 (51 x 203 mm [2 x 6 (51 x 152) at 45º miter]) use an out‑down‑back motion with the rail lock knob loosened. Pull the saw out, toward you, lower the saw head down toward the workpiece, and slowly push the saw back to complete the cut. Do not allow the saw to contact the top of the workpiece while pulling out. The saw may run toward you, possibly causing personal injury or damage to the workpiece.
Cutting off multiple pieces is not recommended but can be done safely by ensuring that each piece is held firmly against the table and fence.
NOTE: To provide greater crosscut capacity with reduced stroke, the blade on the DCS781 extends deeper into the table. As a result, a greater lifting force on the workpiece may be experienced during the cut.
CAUTION: Always use a work clamp to maintain control and reduce the risk of workpiece damage and personal injury, if your hands are required to be within 4″ (100 mm) of the blade during the cut.
NOTE: The rail lock knob  30  shown in Figure A must be loose to allow the saw to slide along its rails  24.
Miter crosscuts are made with the miter arm at some angle other than zero. This angle is often 45º for making corners but can be set anywhere from zero to 50º left or 60 ° right. Make the cut as described above.
When performing a miter cut on workpieces wider than a 2 x 6 that are shorter in length, always place the longer side against fence 12 (Figure Q).
To cut through an existing pencil line on a piece of wood, match the angle as close as possible. Cut the wood a little too long and measure from the pencil line to the cut edge to determine which direction to adjust the miter angle and recut. This will take some practice, but it is a commonly used technique.
Bevel Cuts (Fig. A)
A bevel cut is a crosscut made with the saw blade leaning at an angle to the wood. In order to set the bevel, loosen the bevel lock  13, and move the saw to the left or right as desired. (It is necessary to move the fence to allow clearance.) Once the desired bevel angle has been set, tighten the bevel lock firmly. Refer to the Controls section for detailed instructions on the bevel system.
Bevel angles can be set from 49º right to 49º left and can be cut with the miter arm set between 50º left or 60º right. At some extreme angles, the right or left side fence might have to be removed. To remove the left or right fence, unscrew the fence adjustment knob  16 several turns and slide the fence out.
NOTE: Refer to Fence Adjustment in the Adjustments section for important information on adjusting the fences for certain bevel cuts.
Quality of Cut
The smoothness of any cut depends on a number of variables. Things like the material being cut, blade type, blade sharpness, and rate of cut all contribute to the quality of the cut.
When smoothest cuts are desired for molding and other precision work, a sharp (60 tooth carbide) blade and a slower, even cutting rate will produce the desired results.
Ensure that the material does not move or creep while cutting; clamp it securely in place.
Always let the blade come to a full stop before raising arm.
If small fibers of wood still split out at the rear of the workpiece, stick a piece of masking tape on the wood where the cut will be made. Saw through the tape and carefully remove tape when finished.
For varied cutting applications, refer to the list of recommended saw blades for your saw and select the one that best fits your needs. Refer to saw Blades under Accessories.
Non‑Through‑Cutting (Grooving and Rabbeting)
Instructions in the Crosscuts, Bevel Cuts, and Cutting Compound Miters sections are for cuts made through the full thickness of the material. The saw can also perform non‑through cuts to form grooves or rabbets in the material.
Groove Cut (Fig. A)
Refer to Depth Stop for detailed instructions for setting the depth of the cut. A piece of scrap wood should be used to verify the desired depth of cut.
Hold the wood firmly on the table and against the fence  12. Align the cut area underneath the blade. Position the saw arm fully forward, with a blade in the down position. Turn on the saw by squeezing the trigger switch  1  shown in Figure A. Smoothly, push the saw arm rearward to cut a groove through the workpiece.
Release the trigger switch with the saw arm down. When the saw blade has completely stopped, raise the saw arm. Always let the blade come to a full stop before raising the arm.
To widen the groove, repeat steps 1–4 until the desired width is obtained.

Clamping the Workpiece (Fig. A)

WARNING: To reduce the risk of serious personal injury, turn the tool off, and remove the battery pack before transporting, making any adjustments, cleaning, repairing, or removing/installing attachments or accessories. An accidental start‑up can cause injury.
WARNING: A workpiece that is clamped, balanced, and secure before a cut may become unbalanced after a cut is completed. An unbalanced load may tip the saw or anything the saw is attached to, such as a table or workbench. When making a cut that may become unbalanced, properly support the workpiece and ensure the saw is firmly bolted to a stable surface. Personal injury may occur.
WARNING: The clamp foot must remain clamped above the base of the saw whenever the clamp is used. Always clamp the workpiece to the base of the saw–not to any other part of the work area. Ensure the clamp foot is not clamped on the edge of the base of the saw.
CAUTION: Always use a work clamp to maintain control and reduce the risk of workpiece damage and personal injury.
If you cannot secure the workpiece on the table and against the fence by hand, (irregular shape, etc.) or your hand would be less than 4″ (100 mm) from the blade, a clamp or other fixture must be used.
For best results use the vertical material clamp 23 provided with your saw. Additional clamps can be purchased at your local retailer or DeWALT service center.
Other aids such as spring clamps, bar clamps, or C‑clamps may be appropriate for certain sizes and shapes of material. Use care in selecting and placing these clamps. Take time to make a dry run before making the cut. The left fence will slide from side to side to aid in clamping
To Install Clamp (Fig. A)

1. Insert clamp post into the hole behind the fence 12.
2. Adjust the clamp up turning the knob counterclockwise. And clamp down by turning the knob clockwise. Make sure to firmly clamp the workpiece.

NOTE: Place the clamp on the opposite side of the base when beveling. ALWAYS MAKE DRY RUNS (UNPOWERED) BEFORE FINISHING CUTS TO CHECK THE PATH OF THE BLADE. ENSURE THE CLAMP DOES NOT INTERFERE WITH THE ACTION OF THE SAW OR GUARDS.
Support for Long Pieces
WARNING: To reduce the risk of serious personal injury, turn the tool off, and remove the battery pack before transporting, making any adjustments, cleaning, repairing, or removing/installing attachments or accessories. An accidental start‑up can cause injury.
ALWAYS SUPPORT LONG PIECES.
Never use another person as a substitute for a table extension; as additional support for a workpiece that is longer or wider than the basic miter saw table or to help feed, support, or pull the workpiece.
Support long workpieces using any convenient means such as sawhorses or similar devices to keep the ends from dropping.
Cutting Picture Frames, Shadow Boxes, and Other Four‑Sided
Projects (Fig. R)
To best understand how to make the items listed here, we suggest that you try a few simple projects using scrap wood until you develop a “feel” for your saw.
Your saw is the perfect tool for mitering corners like the one shown in Figure R. Sketch 1 shows a joint made by using the bevel adjustment to bevel the edges of the two boards at 45º each to produce a 90º corner. For this joint, the miter arm was locked in the zero position and the bevel adjustment was locked at 45º. The wood was positioned with the broad flat side against the table and the narrow edge against the fence. The cut could also be made by mitering right and left with the broad surface against the fence.
Cutting Trim Molding and Other Frames (Fig. R)
Sketch 2 in Figure R shows a joint made by setting the miter arm at 45º to miter the two boards to form a 90º corner. To make this type of joint, set the bevel adjustment to zero and the miter arm to 45º. Once again, position the wood with the broad flat side on the table and the narrow edge against the fence.
The two sketches in Figure R are for four‑sided objects only.
As the number of sides changes, so do the miter and bevel angles. The chart below gives the proper angles for a variety of shapes.
– EXAMPLES –

The chart assumes that all sides are of equal length. For a shape that is not shown in the chart, use the following formula: 180º divided by the number of sides equals the miter (if the material is cut vertically) or bevel angle (if the material is cut laying flat).
Cutting Compound Miters (Fig. S)
A compound miter is a cut made using a miter angle and a bevel angle at the same time.
This is the type of cut used to make frames or boxes with slanting sides like the one shown in Figure R.
NOTE: If the cutting angle varies from cut to cut, check that the bevel lock knob and the miter lock handle are securely locked. These must be locked after making any changes in the bevel or miter.
The chart at the end of this manual (Table 1) will assist you in selecting the proper bevel and miter settings for common compound miter cuts. To use the chart, select the desired angle A (Fig. S) of your project and locate that angle on the appropriate arc in the chart. From that point follow the chart straight down to find the correct bevel angle and straight across to find the correct miter angle.
Set your saw to the prescribed angles and make a few trial cuts. Practice fitting the cut pieces together until you develop a feel for this procedure and feel comfortable with it.
Example: To make a 4‑sided box with 26º exterior angles (Angle A, Fig. S), use the upper right arc. Find 26 ° on the arc scale. Follow the horizontal intersecting line to either side to get the miter angle setting on the saw (42 °). Likewise, follow the vertical intersecting line to the top or bottom to get the bevel angle setting on the saw (18 °). Always try cuts on a few scrap pieces of wood to verify the settings on the saw.
Cutting Base Molding (Fig. T)
ALWAYS MAKE A DRY RUN WITHOUT POWER BEFORE MAKING ANY CUTS.
Straight 90 ° cuts:
Position the wood against the fence and hold it in place as shown in Figure T. Turn on the saw, allow the blade to reach full speed, and lower the arm smoothly through the cut.
Cutting Base Molding up to 6.5″ (165 mm) Vertically Against the Fence (Fig. L, T)
NOTE: Use the slide lock transport lever 61, shown in Figure L1, when cutting base molding measuring from 3” to 6.5” (76 mm to 165 mm) high vertically against the fence.
Position material as shown in Figure T.
All cuts should be made with the back of the molding against the fence and with the bottom of the molding against the table.

2. Save the right side of the cut| 1. Miter left 45°
2. Save the right side of the cut

Material up to 6.5″ (165 mm) can be cut as described above.
Cutting Crown Molding
Your miter saw is better suited to the task of cutting crown molding than any tool made. In order to fit properly, crown molding must be compound mitered with extreme accuracy.
The two flat surfaces on a given piece of crown molding are at angles that, when added together, equal exactly 90 °. Most, but not all, crown molding has a top rear angle (the section that fits flat against the ceiling) of 52 ° and a bottom rear angle (the part that fits flat against the wall) of 38 °.
Your miter saw has special pre‑set miter latch points at 31.6 ° left and right for cutting crown molding at the proper angle and bevel stop pawls at 33.9 ° left and right. There is also a mark on the bevel scale at 33.9 °.
The chart below gives the proper settings for cutting crown molding. (The numbers for the miter and bevel settings are very precise and are not easy to accurately set on your
saw.) Since most rooms do not have angles of precisely 90º, you will have to fine-tune your settings anyway.
PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!
Instructions for Cutting Crown Molding Laying Flat and Using the Compound Features (Fig. A, U)

1. Molding laying with broad back surface down flat on saw table 18.
2. Top of molding against fence 12.
3. The settings below are for all standard (U.S.) crown molding with 52 ° and 38 ° angles.

| Inside corner| Outside corner
---|---|---
Left side| 1. Bevel left 33.9°
2. Miter table set at right 31.62°
3. Save the left end of the cut| 1. Bevel right 33.9°
2. Miter table set at left 31.62°
3. Save the left end of the cut
Right side| 1. Bevel right 33.9°
2. Miter table set at left 31.62°
3. Save the right end of the cut| 1.  Bevel left 33.9°
2.  Miter table set at right 31.62°
3.  Save the right end of the cut

When setting bevel and miter angles for all compound miters, remember that:
The angles presented for crown moldings are very precise and difficult to set exactly. Since they can easily shift slightly and very few rooms have exactly square corners, all settings should be tested on scrap molding.
PRETESTING WITH SCRAP MATERIAL IS EXTREMELY IMPORTANT!
Alternative Method for Cutting Crown Molding (Fig. V)
Place the molding on the table at an angle between the sliding fence 12 and the saw table  18, as shown in Figure V. Use of the crown molding fence accessory (DW7084) is highly recommended because of its degree of accuracy and convenience. The crown molding fence accessory is available for purchase from your local dealer.
The advantage of cutting crown molding using this method is that no bevel cut is required. Minute changes in the miter angle can be made without affecting the bevel angle. This way, when corners other than 90 ° are encountered, the saw can be quickly and easily adjusted for them. Use the crown molding fence accessory to maintain the angle at which the molding will be on the wall.
Instructions for Cutting Crown Molding Angled Between the Fence and Base of the Saw for All Cuts

1. Angle the molding so the bottom of the molding (the part which goes against the wall when installed) is against the fence and the top of the molding is resting on the base of the saw, as shown in Figure V.
2. The angled “flats” on the back of the molding must rest squarely on the fence and base of the saw.

Special Cuts
NEVER MAKE ANY CUT UNLESS THE MATERIAL IS SECURED ON THE TABLE AND AGAINST THE FENCE.
Aluminum Cutting (Fig. A, W)
ALWAYS USE THE APPROPRIATE SAW BLADE MADE ESPECIALLY FOR CUTTING ALUMINUM.
These are available at your local DeWALT retailer or DeWALT service center. Certain workpieces, due to their size, shape, or surface finish, may require the use of a clamp or fixture to prevent movement during the cut. Position the material so that you will be cutting the thinnest cross-section, as shown in Figure W. Figure W also illustrates the wrong way to cut these extrusions.
Use a stick wax cutting lubricant when cutting aluminum. Apply the stick wax directly to the saw blade  39  before cutting. Never apply stick wax to a moving blade.
The wax, available at most hardware stores and industrial mill supply houses, provides proper lubrication and keeps chips from adhering to the blade.
Be sure to properly secure the workpiece.
Refer to saw Blades under Accessories for the correct saw blade.
Bowed Material (Fig. X, Y)
When cutting bowed material always position it as shown in Figure X and never like that shown in Figure Y. Positioning the material incorrectly will cause it to pinch the blade near the completion of the cut.
Cutting Plastic Pipe or Other Round Material
Plastic pipe can be easily cut with your saw. It should be cut just like wood and ClAMPED OR HELD FIRMLY TO THE FENCE TO KEEP IT FROM ROLLING. This is extremely important when making angle cuts.
Cutting Large Material (Fig. Z)
Occasionally you will encounter a piece of wood a little too large to fit beneath the lower guard. If this occurs, simply place your right thumb on the upper side of the guard and roll the guard up just enough to clear the workpiece, as shown in Figure Z. Avoid doing this as much as possible, but if need be, the saw will operate properly and make the bigger cut. NEVER TIE, TAPE, OR OTHERWISE HOLD THE GUARD OPEN WHEN OPERATING THIS SAW.

MAINTENANCE

WARNING: To reduce the risk of serious personal injury, turn the tool off, and remove the battery pack before transporting, making any adjustments, cleaning, repairing, or removing/installing attachments or accessories. An accidental start‑up can cause injury.
WARNING: To reduce the risk of serious personal injury, DO NOT touch the sharp points on the blade with your fingers or hands while performing any maintenance.
DO NOT use lubricants or cleaners (particularly spray or aerosol) in the vicinity of the plastic guard. The polycarbonate material used in the guard is subject to attack by certain chemicals.

1. All bearings are sealed. They are lubricated for life and need no further maintenance.
2. Periodically clean all dust and wood chips from around AND UNDER the base and the rotary table. Even though slots are provided to allow debris to pass through, some dust will accumulate.

Cleaning
WARNING: Blow dirt and dust out of all air vents with clean, dry air at least once a week. To minimize the risk of eye injury, always wear ANSI Z87.1-approved eye protection when performing this procedure.
WARNING: Never use solvents or other harsh chemicals for cleaning the non‑metallic parts of the tool. These chemicals may weaken the plastic materials used in these parts.
Use a cloth dampened only with water and mild soap. Never let any liquid get inside the tool; never immerse any part of the tool in a liquid.
Worklight Cleaning
For the best work light performance, perform the following maintenance regularly.

1. Carefully clean sawdust and debris from the work light lens with a cotton swab.
2. DO NOT use solvents of any kind, they may damage the lens.
3. Dust build‑up can block the work light and prevent it from accurately indicating the line of cut.
4. Follow the miter saw’s instruction manual to remove and install the blade.
5. With the blade removed from the saw, clean pitch, and build‑up from the blade. Pitch and debris can interfere with the work light and prevent it from accurately indicating the line of cut.

SPECIFICATIONS

Dust Duct Cleaning
Depending on your cutting environment, sawdust can clog the dust duct and may prevent dust from flowing away from the cutting area properly. With the saw unplugged and the saw head raised fully, low-pressure air or a large-diameter dowel rod can be used to clear the dust out of the dust duct.
