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 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 which may ignite the 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 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 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. 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 residual current device (RCD) protected supply. Use of an RCD 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 hat 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 power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising 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 jewellery. Keep your hair and clothing away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts. Batteries| Chargers/Charge Times (Minutes)

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 it 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 behaviour 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 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 Mitre Saws
a ) Mitre 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 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 towards 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 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 mitre saw is mounted or placed on a level, firm work surface before use. A level and firm work surface reduce the risk of the mitre saw becoming unstable.
k ) Plan your work. Every time you change the bevel or mitre angle setting, make sure the adjustable fence is set correctly to support the workpiece and 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 mitre 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 mitre 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 mitre 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 Mitre Saws

• WARNING: Do not connect to the mains power supply into the unit until complete instructions are read and understood.
• 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, recessed sides of blade clamps are against the blade and arbour 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 tools and possible personal injury may occur.
• NEVER CUT METALS or masonry. Either of these can cause the carbide tips to fly off the blade at high speeds causing serious injury.
• 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.
• DO NOT place either hand in the blade area when the saw is connected to the power source. Inadvertent blade activation may result in serious injury.
• NEVER REACH AROUND OR BEHIND THE SAW BLADE. A blade can cause serious injury.
• DO NOT REACH UNDERNEATH THE SAW unless it is unplugged and turned off. Contact with the saw blade may cause personal injury.
• SECURE THE MACHINE TO A STABLE SUPPORTING SURFACE. Vibration can possibly cause the machine to slide, walk, or tip over, causing serious injury.
• USE ONLY CROSSCUT SAW BLADES recommended for mitre saws. For best results, do not use carbide-tipped blades with hook angles in excess of 7 degrees. Do not use blades with deep gullets. These can deflect and contact the guard and can cause damage to the machine and/ or serious injury.
• USE ONLY BLADES OF THE CORRECT SIZE AND TYPE specified for this tool to prevent damage to the machine and/or serious injury (complying with EN847‑1).
• INSPECT BLADE FOR CRACKS or other damage prior to operation. A cracked or damaged blade can come apart and pieces can be thrown at high speeds, causing serious injury. Replace cracked or damaged blades immediately. Observe the maximum speed marked on the saw blade.
• THE MAXIMUM SPEED OF THE SAW BLADE shall always be greater than or at least equal to the speed marked on the rating plate of the tool.
• THE SAW BLADE DIAMETER must be in accordance with the markings on the rating plate of the tool.
• CLEAN THE BLADE AND BLADE CLAMPS prior to operation. Cleaning the blade and blade clamps allows you to check for any damage to the blade or blade clamps. A cracked or damaged blade or blade clamp can come apart and pieces can be thrown at high speeds, causing serious injury.
• DO NOT USE WARPED BLADES. Check to see if the blade runs true and is free from vibration. A vibrating blade can cause damage to the machine and/or serious injury.
• 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.
• KEEP GUARD IN PLACE and in working order.
• ALWAYS USE THE KERF PLATE AND REPLACE THIS PLATE WHEN DAMAGED. Small chip accumulation under the saw may interfere with the saw blade or may cause instability of the workpiece when cutting.
• USE ONLY BLADE CLAMPS SPECIFIED FOR THIS TOOL to prevent damage to the machine and/or serious injury.
• MAKE SURE to use the correct saw blade for the material to be cut.
• CLEAN THE MOTOR AIR SLOTS of chips and sawdust. Clogged motor air slots can cause the machine to overheat, damaging the machine and possibly causing a short which could cause serious injury.
• NEVER LOCK THE SWITCH IN THE “ON” POSITION. Severe personal injury may result.
• NEVER STAND ON A TOOL. Serious injury could occur if the tool is tipped or if the cutting tool is unintentionally contacted.
• WARNING: Cutting plastics, sap-coated wood, and other materials may cause melted material to accumulate on the blade tips and the body of the saw blade, increasing the risk of blade overheating and binding while cutting.
• WARNING: Always wear proper personal hearing protection. Under some conditions and duration of use, noise from this product may contribute to hearing loss. Be aware of the following factors influencing exposure to noise:
• Use saw blades designed to reduce the emitted noise,
• Use only well-sharpened saw blades, and
• Use specifically designed noise‑reduction saw blades.

WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also, use a face or dust mask if the cutting operation is dusty.
WARNING: Use of this tool can generate and/or disperse dust, which may cause serious and permanent respiratory or another injury.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• lead from lead‑based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well-ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth and eyes, or lay on the skin may promote the absorption of harmful chemicals.

WARNING: Use of this tool can generate and/or disperse dust, which may cause serious and permanent respiratory or another injury. Always use approved respiratory protection appropriate for dust exposure.
WARNING: We recommend the use of a residual current device with a residual current rating of 30mA or less.

Residual Risks
The following risks are inherent to the use of saws:

• Injuries are caused by touching the rotating parts.
  In spite of the application of the relevant safety regulations and the implementation of safety devices, certain residual risks cannot be avoided. These are:

• Impairment of hearing.

• Risk of accidents caused by the uncovered parts of the rotating saw blade.

• Risk of injury when changing the blade.

•  Risk of squeezing fingers when opening the guards.

• Health hazards caused by breathing dust developed when sawing wood, especially oak, beech and MDF. The following factors increase the risk of breathing problems:

• No dust extractor connected when sawing wood.

Charging a Battery (Fig. D)

1. Plug the charger into an appropriate outlet before inserting the battery pack.
2. Insert the battery pack  16  into the charger, making sure the battery pack is fully seated in the charger. The red (charging) light will blink repeatedly indicating that the charging process has started.
3. The completion of the charge will be indicated by the red light remaining ON continuously.
   The battery pack is fully charged and may be used at this time or left in the charger. To remove the battery pack from the charger, push the battery release button  44  on the battery pack.

Note: To ensure maximum performance and life of lithium‑ion battery packs, charge the battery pack fully before first use.
Charger Operation
Refer to the indicators below for the charge status of the battery pack.
Charge Indicators * The red light will continue to blink, but a yellow indicator light will be illuminated during this operation. Once the battery pack has reached an appropriate temperature, the yellow light will turn off and the charger will resume the charging procedure.
The compatible charger(s) will not charge a faulty battery pack. The charger will indicate a faulty battery by refusing to light.
Note: This could also mean a problem with a charger.
If the charger indicates a problem, take the charger and battery pack to be tested at an authorized service center.
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 will charge at a slower rate than a warm battery pack. The battery pack will charge at that slower rate throughout the entire charging cycle and will not return to the maximum charge rate even if the battery pack warms.
The DCB118 charger is 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
XR 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 if the Electronic Protection System engages. If this occurs, place the lithium‑ion battery pack on the charger until it is fully charged.
Wall Mounting
These 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 25.4 mm long with a screw head diameter of 7–9 mm, screwed into wood to an optimal depth leaving approximately 5.5 mm of the screw exposed.

• Charge the battery packs only in DEWALT  chargers.

• DO NOT splash or immerse in water or other liquids.

• Do not store or use the tool and battery pack in locations where the temperature may fall below 4 ˚C (34 ˚F) (such as outside sheds or metal buildings in winter), or reach or exceed 40 ˚C (104 ˚F) (such as outside sheds or metal buildings in summer).

• Do not incinerate the battery pack even if it is severely damaged or is completely worn out. The battery pack can explode in a fire. Toxic fumes and materials are created when lithium‑ion battery packs are burned.

• If battery contents come into contact with the skin, immediately wash the area with mild soap and water. If battery liquid gets into the eye, rinse water over the open eye for
  15 minutes or until irritation ceases. If medical attention is needed, the battery electrolyte is composed of a mixture of liquid organic carbonates and lithium salts.

• Contents of opened battery cells may cause respiratory irritation. Provide fresh air. If symptoms persist, seek medical attention.

** WARNING: Burn hazard. Battery liquid may be flammable if exposed to spark or flame.
WARNING: Never attempt to open the battery pack for any reason. If the battery pack case is cracked or damaged, do not insert it into the charger. Do not crush, drop or damage the battery pack. Do not use a battery pack or charger that has received a sharp blow, been dropped, run over, or damaged in any way (i.e., pierced with a nail, hit with a hammer, stepped on). Electric shock or electrocution may result. Damaged battery packs should be returned to a service center for recycling.
WARNING: Fire hazard. Do not store or carry the battery pack so that metal objects can contact exposed battery terminals. For example, do not place the battery pack in aprons, pockets, tool boxes, product kit boxes, drawers, etc., with loose nails, screws, keys, etc.
CAUTION: When not in use, place the tool on its side on a stable surface where it will not cause a tripping or falling hazard. Some tools with large battery packs will stand
upright on the battery pack but may be easily knocked over.
Transportation
WARNING: Fire hazard. Transporting batteries can possibly cause a fire if the battery terminals inadvertently come in contact with conductive materials. When transporting batteries, make sure that the battery terminals are protected and well insulated from materials that could contact them and cause a short circuit. NOTE: Lithium‑ion batteries should not be put in checked baggage.
DEWALT batteries comply with all applicable shipping regulations as prescribed by industry and legal standards which include UN Recommendations on the Transport of Dangerous Goods; International Air Transport Association (IATA) Dangerous Goods Regulations, International Maritime Dangerous Goods (IMDG) Regulations, and the European Agreement Concerning The International Carriage of Dangerous Goods by Road (ADR). Lithium‑ion cells and batteries have been tested to section 38.3 of the UN Recommendations on the Transport of Dangerous Goods Manual of Tests and Criteria.
In most instances, shipping a DEWALT battery pack will be excepted from being classified as a fully regulated Class 9 Hazardous Material. In general, only shipments ontaining a lithium‑ion battery with an energy rating greater than 100 Watt Hours (Wh) will require being shipped as fully regulated Class 9. All lithium‑ion batteries have the Watt Hour rating marked on the pack. Furthermore, due to regulation complexities, DEWALT does not recommend air shipping lithium‑ion battery packs alone regardless of Watt Hour rating. Shipments of tools with batteries (combo kits) can be air shipped as excepted if the Watt Hour rating of the battery pack is no greater than 100 Wh.
Regardless of whether a shipment is considered excepted or fully regulated, it is the shipper’s responsibility to consult the latest regulations for packaging, labeling/marking, and documentation requirements.
The information provided in this section of the manual is provided in good faith and believed to be accurate at the time the document was created. However, no warranty, expressed or implied, is given. It is the buyer’s responsibility to ensure that its activities comply with the applicable regulations.
Transporting the FlEXVOlT TM Battery
The DEWALT FLEXVOLT TM battery has two modes: Use and Transport.
Use Mode: When the FLEXVOLT TM battery stands alone or is in a DEWALT 18V product, it will operate as an 18V battery. When the FLEXVOLT TM battery is in a 54V or a 108V (two 54V batteries) product, it will operate as a 54V battery.
Transport Mode: When the cap is attached to the FLEXVOLT TM battery, the battery is in Transport mode. Keep the cap for shipping. When in Transport mode, strings of cells are electrically disconnected within the pack resulting in 3 batteries with a lower Watt hour (Wh) rating as compared to 1 battery with a
higher Watt hour rating. This increased quantity of 3 batteries with the lower Watt hour rating can exempt the pack from certain shipping regulations that are imposed upon the higher Watt hour batteries.
For example, the Transport Wh rating might indicate 3 x 36 Wh, meaning 3 batteries of 36 Wh each. The Use Wh rating might indicate 108 Wh (1 battery implied).
Storage Recommendations**

1. The best storage place is one that is cool and dries away from direct sunlight and excess heat or cold. For optimum battery performance and life, store battery packs at room temperature when not in use.
2. For long storage, it is recommended to store a fully charged battery pack in a cool, dry place out of the charger for optimal results.
   Note: Battery packs should not be stored completely depleted of charge. The battery pack will need to be recharged before use.

To turn the saw on, push the lock‑off lever  18  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  36  is provided in the trigger for the insertion of a padlock to lock the switch off.
Your saw is not equipped with an automatic electric blade brake, but the saw blade should stop within 5 seconds of trigger release. This is not adjustable. If the stop time repeatedly exceeds 5 seconds, have the tool serviced by an authorized DEWALT service center.
Always be sure the blade has stopped before removing it from the kerf.
Dust Extraction (Fig. A, I)
WARNING: To reduce the risk of serious personal injury, turn the tool off and disconnect the battery pack before making any adjustments, performing any cleaning or maintenance, or removing/installing attachments or accessories. An accidental start‑up can cause injury.
WARNING: Certain dust, such as oak or beech dust, is considered carcinogenic, especially in connection with wood‑treatment additives.

• Always use dust extraction.
• Provide good ventilation of the workspace.
• It is recommended to wear an appropriate respirator.

Your saw has a built‑in dust port  14  that allows either the supplied dust bag  37   or a shop vacuum system to be connected.
To Attach the Dust Bag

1. Fit the dust bag  37  to the dust port  14  as shown in Figure I.

To Empty the Dust Bag

1. Remove dust bag  37  from the saw and gently shake or tap the dust bag to empty.
2. Reattach the dust bag back onto the dust port  14.

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.
CAUTION: Never operate this saw unless the dust bag or DEWALT dust extractor is in place. Wood dust may create a breathing hazard.
Cutting with your Saw (Fig. A)
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 100 mm from the blade, a clamp or other fixture must be used. Refer to Clamping the Workpiece for more information.
If the slide feature is not used, ensure the saw head is pushed back as far as possible and the rail lock knob  20  is tightened. This will prevent the saw from sliding along its rails as the workpiece is engaged.
NOTE: DO NOT CUT METAls 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
straight Cut (Fig. A, g1, g2)
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, 20  tightened, turn on the saw by squeezing the trigger switch  1.
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 51 mm x 102 mm, use an out‑down‑back motion with the rail lock knob  20  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 blade 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.
WARNING: 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 100 mm of the blade during the cut.
NOTE: The rail lock knob  20  shown in Figure A must be loose to allow the saw to slide along its rails.
Mitre Cuts (Fig. J, K)
Mitre 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 48º left or 48 ° right. To miter the saw, loosen the miter lock knob  5  by turning it anticlockwise. Pull up on the miter lock knob to move the miter arm 7 to the miter angle desired on the miter scale  8. Turn the miter lock knob clockwise to tighten. Make the cut as described above.
When performing a miter cut on workpieces wider than 51 mm x 102 mm that are shorter in length, always place the longer side against the fence (Fig. K).
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. l1, l2)
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 knob  12, and move the saw to the left as desired. Once the desired bevel angle has been set, tighten the bevel lock firmly. Bevel angles can be set from 0º right to 48º left.
To set the bevel angle past 45º to 48º,

1. Loosen the bevel lock knob  12.
2. Tilt the saw head slightly to slide the bevel override  25  to one side.
3. Move the saw head to 48º.
4. Tighten the bevel lock knob.

Quality of Cut
The smoothness of any cut depends on a number of variables. Things like material being cut, blade type, blade sharpness, and rate of cut all contribute to the quality of the cut.
When the smoothest cuts are desired for molding and other precision work, a sharp (60 tooth carbide tip) 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 the 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 Optional Accessories.
Clamping the Workpiece
WARNING: To reduce the risk of serious personal injury, turn the tool off and disconnect the battery pack before making any adjustments, performing any cleaning or maintenance, 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.
WARNING: 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 100 mm of
the blade during the cut.
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 100 mm from the blade, a clamp or other fixture must be used.
Use the material clamp provided with your saw. To purchase a material clamp, contact 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.
To Install Clamp (Fig. M)

1. With clamp  38  facing the back of the miter saw, insert the clamp rod into hole  21 behind the fence. Ensure the groove at the bottom of the clamp rod is fully inserted into hole  21.
2. Rotate the clamp 180º toward the front of the miter saw.
3. Loosen the knob to adjust the clamp arm up or down, then use the fine adjust knob 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.

ADJUSTMENTS

WARNING: To reduce the risk of serious personal injury, turn the tool off and disconnect the battery pack before making any adjustments, performing any cleaning or maintenance, or removing/installing attachments or accessories. An accidental start‑up can cause injury.
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
instructions below to adjust your saw.
Once made, these adjustments should remain accurate. Take a little time now to follow these directions carefully to maintain the accuracy of which your saw is capable.
Mitre Scale Adjustment (Fig. J, N)
Lock the saw head in the down position. Unlock the miter lock knob  5  and swing the miter arm  7  until it locks at the 0 ° miter position. Do not lock the miter lock knob. Place a square against the saw’s fence and blade, as shown in Figure N. (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, loosen the three screws ( 9, Fig. J) that hold the miter scale  8  and move the miter arm and the scale left or right until the blade is perpendicular to the fence, as measured with the square. Retighten the three screws.
Bevel Square to Table Adjustment (Fig. A, L1, O)
To align the blade square to the table, lock the operating handle in the down position with the lockdown pin  23. Place a square against the blade, ensuring the square is not on top of a tooth. Loosen the bevel lock knob  12  and ensure the bevel arm is firmly against the 0 ° bevel stop. Rotate the 0 ° bevel adjustment screw  41  with a 4 mm hex key (not provided) as necessary so that the blade is at 0 ° bevel to the table, as measured with the square.
Bevel Stop 45º Left Adjustment (Fig. A, L1, L2)
To adjust the left 45 ° bevel stop, first, loosen the bevel lock knob and tilt the head until it stops. Verify that the bevel override  25  is in the 45 ° position; and if the bevel pointer  40  does not indicate exactly 45 °, turn the 45 ° bevel adjustment screw  42  until the bevel pointer 40 reads 45 °.
Guard Actuation and Visibility (Fig. A, X)
CAUTION: Pinch hazard. To reduce the risk of injury, keep your thumb underneath the operating handle when pulling the handle down. The lower guard will move up as the operating handle is pulled down, which could cause pinching.
The lower guard  4  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.
Before each use or after making adjustments, cycle the arm (unpowered) and make sure the guard opens smoothly and closes fully. It should not contact the blade. With the arm up, raise the guard (unpowered) as shown in Figure X and release. The guard should fully close rapidly.
Do not operate the saw if the guard does not move freely and fully close rapidly. Never clamp or tie the guard in an open position when operating the saw.
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, there are openings in the guard, and safety glasses should be worn at all times.
Rail Guide Adjustment (Fig. A)
Periodically check the rails  13  for any play or clearance. The rails can be cleaned with a dry clean cloth. The right rail can be adjusted with the rail adjustment screw  19  shown in Figure A. To reduce clearance, use a 4 mm hex wrench and rotate the set screw clockwise gradually while sliding the saw head back and forth. Reduce play while maintaining minimum slide force.
Support for Long Pieces
WARNING: To reduce the risk of serious personal injury, turn the tool off and disconnect the battery pack before making any adjustments, performing any cleaning or maintenance, 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. P, Q)
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 P. Sketch A in Figure Q 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. Q)
Sketch B in Figure Q 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.
Figures P and Q 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 –

NUMBER OF SIDES| MITRE OR BEVEL ANGLE
4| 45°
5| 36°
6| 30°
7| 25.7°
8| 22.5°
9| 20°
10| 18°

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 Mitres (Fig. R)
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 table below 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. R) 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. R), 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. S)
Straight 90º cuts:
Position the wood against the fence and hold it in place as shown in Figure S. Turn on the saw, allow the blade to reach full speed, and lower the arm smoothly through the cut.
Cutting Base Molding Up to 89 mm High Vertically Against the Fence
Position material as shown in Figure S.
All cuts should be made with the back of the molding against the fence and with the bottom of the molding against the table.

| INSIDE CORNER| OUTSIDE CORNER
---|---|---
Left side| Mitre left 45°| Mitre right 45°
Save the left side of the cut| Save the left side of the cut
Right side| Mitre right 45°| Mitre left 45°
Save the right side of the cut| Save the right side of the cut

Material up to 89 mm can be cut as described above. The width of the material cannot exceed 19 mm.

Cutting Crown Molding (Fig. T, U)
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 detent points at 31.6 ° left and right for cutting crown molding at the proper angle. There is also a mark on the bevel scale at 33.8 °.
The Bevel Setting/Type of Cut chart 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 90 °, 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

1. Lay the molding with a broad back surface down flat on the saw table (Fig. T).
2. The settings below are for all Standard (U.S.) crown molding with 52 ° and 38 ° angles.
   BEVEL SETTING| TYPE OF CUT
   ---|---
   33.8°| LEFT SIDE, INSIDE CORNER:
   Top of molding against fence
   Mitre table set right 31.62°
   Save the left end of the cut
   33.8°| RIGHT SIDE, INSIDE CORNER:
   Bottom of molding against fence
   Mitre table set left 31.62°
   Save the left end of the cut
   33.8°| LEFT SIDE, OUTSIDE CORNER:
   Bottom of molding against fence
   Mitre table set left 31.62°
   Save the right end of the cut
   33.8°| RIGHT SIDE, OUTSIDE CORNER:
   Top of molding against fence
   Mitre table set right 31.62°
   Save the right end of the cut

NOTE: 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!
An alternative method for Cutting Crown Molding
Place the molding at an angle between fence  11  and saw table  43, as shown in Figure U.
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 90º are encountered, the saw can be quickly and easily adjusted for them.
Instructions for Cutting Crown Molding Angled Between the Fence and Base of the Saw for All Cuts
This saw can cut up to 14 mm x 92 mm crown molding nested.

1. Place the molding at an angle between fence  11  and saw table  43, as shown in Figure U.
2. The angled “flats” on the back of the molding must rest squarely on the fence and saw table.
   | INSIDE CORNER| OUTSIDE CORNER
   ---|---|---
   Left side| Mitre left 45°| Mitre right 45°
   Save the right side of the cut| Save the right side of the cut
   Right side| Mitre right 45°| Mitre left 45°
   Save the left side of the cut| Save the left side of the cut

Special Cuts
NEVER MAKE ANY CUT UNLESS THE MATERIAL IS SECURED ON THE TABLE AND AGAINST THE FENCE.
Bowed Material (Fig. V, W)
When cutting bowed material always position it as shown in Figure V and never like that shown in Figure W. Positioning the material incorrectly will cause it to pinch the blade near the completion of the cut.
Cutting Round Material
ROUNDED MATERIAL SHOULD BE CLAMPED OR HELD FIRMLY TO THE FENCE TO KEEP IT FROM ROLLING. This is extremely important when making angle cuts.
Cutting Large Material (Fig. X)
Occasionally you will encounter a piece of wood a little too large to fit beneath the lower guard. To clear the guard over the wood, with the saw off and your right hand on the
operating handle, place your right thumb outside of the upper portion of the guard and roll the guard up just enough to clear the wood, as shown in Figure X. Release the guard prior to starting the motor. The guard mechanism will function properly during the cut. Only do this when necessary. NEVER TIE, TAPE, OR OTHERWISE HOLD THE GUARD OPEN WHEN OPERATING THIS SAW.
