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.
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1. Work Area Safetya ) Keep work area clean and well lit. Cluttered or dark areas invite accidents.

   • 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.
   • Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2. Electrical Safety

   • 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.
   • 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.
   • Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
   • 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.
   • 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.
     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

   • 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.
   • 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.
   • 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.
   • 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.
   • Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
   • 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.
   • If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust‑related hazards.
   • Do not let familiarity gained from 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

   • 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.
   • 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.
   • 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.
   • 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.
   • 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.
   • Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.
   • 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.
   • 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

   • 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.
   • Use power tools only with specifically designated battery packs. Use of any other battery packs may create a risk of injury and fire.
   • When 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.
   • Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.
   • 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.
   • Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature above 130 °C may cause explosion.
   • 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

   • 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.
   • Never service damaged battery packs. Service of battery packs should only be performed by the manufacturer or authorized service providers.

Safety Instructions for All Saws Cutting Procedures

1. DANGER: Keep hands away from cutting area and the blade. Keep your second hand on auxiliary handle, or motor housing. If both hands are holding the saw, they cannot be cut by the blade.
2. Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.
3. Adjust the cutting depth to the thickness of the workpiece. Less than a full tooth of the blade teeth should be visible below the workpiece.
4. Never hold the workpiece in your hands or across your leg while cutting. Secure the workpiece to a stable platform. It is important to support the work properly to minimize body exposure, blade binding, or loss of control.
5. Hold the power tool by insulated gripping surfaces, when performing an operation where the cutting tool may contact hidden wiring. Contact with a “live” wire will also make exposed metal parts of the power tool “live” and could give the operator an electric shock.
6. When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding.
7. Always use blades with correct size and shape (diamond versus round) of arbor holes. Blades that do not match the mounting hardware of the saw will run off-center, causing loss of control.
8. Never use damaged or incorrect blade washers or bolt. The blade washers and bolt were specially designed for your saw, for optimum performance and safety
   of operation.

FURTHER SAFETY INSTRUCTIONS FOR ALL SAWS
Kickback Causes and Related Warnings

• Kickback is a sudden reaction to a pinched, jammed or misaligned saw blade, causing an uncontrolled saw to lift up and out of the workpiece toward the operator;
• When the blade is pinched or jammed tightly by the kerf closing down, the blade stalls and the motor reaction drives the unit rapidly back toward the operator;
• If the blade becomes twisted or misaligned in the cut, the teeth at the back edge of the blade can dig into the top surface of the wood causing the blade to climb out of the kerf and jump back toward the operator.

Kickback is the result of saw misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

1. Maintain a firm grip with both hands on the saw and position your arms to resist kickback forces. Position your body to either side of the blade, but not in line with the blade. Kickback could cause the saw to jump backwards, but kickback forces can be controlled by the operator, if proper precautions are taken.

2. When blade is binding, or when interrupting a cut for any reason, release the trigger and hold the saw motionless in the material until the blade comes to a complete stop. Never attempt to remove the saw from the work or pull the saw backward while the blade is in motion or kickback may occur. Investigate and take corrective actions to eliminate the cause of blade binding.

3. When restarting a saw in the workpiece, centre the saw blade in the kerf so that the saw teeth are not engaged into the material. If saw blade binds, it  may walk up or kickback from the workpiece as the saw is restarted.

4. Support large panels to minimise the risk of blade pinching and kickback. Large panels tend to sag under their own weight. Supports must be placed under the panel on both sides, near the line of cut and near the edge of the panel.

5. Do not use dull or damaged blades. Unsharpened
   or improperly set blades produce narrow kerf causing excessive friction, blade binding and kickback.

6.  Blade depth and bevel adjusting locking levers must be tight and secure before making cut. If blade adjustment shifts while cutting, it may cause binding and kickback.

7. Use extra caution when sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.

Lower Guard Function Safety Instructions

1. Check the lower guard for proper closing before each use. Do not operate the saw if lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position.
2. If saw is accidentally dropped, lower guard may be bent. Raise the lower guard with the retracting handle and make sure it moves freely and does not touch the blade or any other part, in all angles and depths of cut.
3. Check the operation of the lower guard spring. If the guard and the spring are not operating properly, they must be serviced before use. Lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
4. The low guard may be retracted manually only for special cuts such as “plunge cuts” and “compound cuts.” Raise the lower guard by retracting the handle and as soon as blade enters the material, the lower guard must be released. For all other sawing, the lower guard should operate automatically.
5. Always observe that the lower guard is covering the blade before placing saw down on bench or floor. An unprotected, coasting blade will cause the saw to walk backwards, cutting whatever is in its path. Be aware of the time it takes for the blade to stop after switch is released.

Additional Safety Instructions for Circular Saws

• Wear ear protectors. Exposure to noise can cause hearing loss.
• Wear a dust mask. Exposure to dust particles can cause breathing difficulty and possible injury.
• Do not use blades of larger or smaller diameter than recommended. For the proper blade rating refer to the Technical Data. Use only the blades specified in this manual, complying with EN847-1.
• Never use abrasive cut‑off wheels.
• Do not use water feed attachments.
• Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body leaves it unstable and may lead to loss of control.
• Use only saw blades that are marked with a speed equal or higher than the speed marked on the tool.
• Avoid overheating the blade tips.
• Install the dust extraction port onto the saw before use.

Residual Risks
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 personal injury due to flying particles.
• Risk of burns due to accessories becoming hot during operation.
• Risk of personal injury due to prolonged use.

Chargers

DEWALT chargers require no adjustment and are designed to be as easy as possible to operate.
Electrical Safety
The electric motor has been designed for one voltage only. Always check that the battery pack voltage corresponds to the voltage on the rating plate. Also make sure that the voltage of your charger corresponds to that of your mains. Your DEWALTcharger is double insulated in accordance with EN60335; therefore no earth wire is required. If the supply cord is damaged, it must be replaced only by DEWALT or an authorised service organisation.
Mains Plug Replacement (U.K. & Ireland Only)
If a new mains plug needs to be fitted:

• Safely dispose of the old plug.
• Connect the brown lead to the live terminal in the plug.
• Connect the blue lead to the neutral terminal.

WARNING: No connection is to be made to the earth terminal. Follow the fitting instructions supplied with good quality plugs. Recommended fuse: 3 A.

Using an Extension Cable
An extension cord should not be used unless absolutely necessary. Use an approved extension cable suitable for the power input of your charger (see Technical Data). The minimum conductor size is 1 mm2; the maximum length is 30 m. When using a cable reel, always unwind the cable completely.

Charging a Battery (Fig. B)

1. Plug the charger into an appropriate outlet before inserting battery pack.
2. Insert the battery pack  1  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 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  13  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. * 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 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 authorised service centre.

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 maximum charge rate even if the battery pack warms.

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 air flow. 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. Align the slots on the back of the charger with the exposed screws and fully engage them in the slots.

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. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

When the level of charge in the battery is below the usable limit, the fuel gauge will not illuminate and the battery will need to be recharged. NOTE: The fuel gauge is only an indication of the charge left on the battery pack. It does not indicate tool functionality and is subject to variation based on product components, temperature and end‑user application.

Changing Blades

To Install the Blade (Fig. A, C)

WARNING: Remove battery before service, adjustment, installing or removing accessories.

1. Place inner clamp washer  20  on saw spindle  17  properly.
2. Retract the lower blade guard  7  and place blade on saw spindle against the inner clamp washer, making sure that the blade will rotate in the proper direction (the direction of the rotation arrow on the saw blade and the teeth must point in the same direction as the direction of rotation arrow on the lower blade guard). Do not assume that the printing on the blade will always be facing you when properly installed. When retracting the lower blade guard to install the blade, check the condition and operation of the lower blade guard to assure that it is working properly. Make sure it moves freely and does not touch the blade or any other part, in all angles and  depths of  cut.
3. Place outer clamp washer  19  on saw spindle with the large flat surface against the blade with beveled side facing out.
4. Thread blade clamping screw  8  into saw spindle by hand (screw has left‑hand threads and must be turned counterclockwise to tighten).
5. Depress the blade lock button  21  while turning the saw spindle with the hex key   14  until the blade lock engages and the blade stops rotating.
6. Tighten the blade clamping screw firmly with the blade wrench.

NOTE: Never engage the blade lock while saw is running, or engage in an effort to stop the tool. Never turn the saw on while the blade lock is engaged. Serious damage to your saw will result.

To Replace the Blade (Fig.  A, C)
WARNING: Remove battery before service, adjustment, installing or removing accessories.

1. To loosen the blade clamping screw  8 , depress the blade lock button  21  and turn the saw spindle with the hex key   14  until the blade lock engages and the blade stops rotating. With the blade lock engaged, turn the blade clamping screw clockwise with the hex key (screw has left‑hand threads and must be turned clockwise to loosen).
2. Remove the blade clamping screw  8  and outer clamp washer  19  only. Remove old blade.
3. Clean any sawdust that may have accumulated in the guard or clamp washer area and check the condition and operation of the lower blade guard as previously outlined. Do not lubricate this area.
4. Select the proper blade for the application (see Blades). Always use blades that are the correct size (diameter) with the proper size and shape center hole for mounting on the saw spindle. Always assure that the maximum recommended speed (rpm) on the saw blade meets or exceeds the speed (rpm) of the saw.
5. Follow steps 2 through 6 under To Install the Blade, making sure that the blade will rotate in the proper direction.

Lower Blade Guard
WARNING: The lower blade guard is a safety feature which reduces the risk of serious personal injury. Never use the saw if the lower blade guard is missing, damaged, misassembled or not working properly. Do not rely on the lower blade guard to protect you under all circumstances. Your safety depends on following all warnings and precautions as well as proper operation of the saw. Check lower blade guard for proper closing before each use as outlined in Further Safety Instructions for All Saws. If the lower blade guard is missing or not working properly, have the saw serviced before using.
To assure product safety and reliability, repair, maintenance and adjustment should be performed by an authorized service center or other qualified service organization, always using identical replacement parts.

Checking the Lower Guard (Fig. A)

1. Turn tool off and disconnect from power supply.
2. Rotate the lower blade guard retracting lever  6  from the fully closed position to the fully open position.
3. Release the lever and observe the guard  7  return to the fully closed position.

The tool should be serviced by a qualified service center if it:

• fails to return to the fully closed position,
• moves intermittently or slowly, or
• contacts the blade or any part of the tool in all angles and depth of cut.

Blades

WARNING: To minimize the risk of eye injury, always use eye protection. Carbide is a hard but brittle material. Foreign objects in the workpiece such as wire or nails can cause tips to crack or break. Only operate saw when proper saw blade guard is in place. Mount blade securely in proper rotation before using, and always use a clean, sharp blade.
WARNING : Do not cut metal, plastic, concrete, masonry or fiber cement materials with this saw. Do not use abrasive wheels or blades. A dull blade will cause slow inefficient cutting, overload on the saw motor, excessive splintering, and could increase the possibility of kickback. Please refer to the table below to determine the correct size replacement blade for your model saw.

Cutting Depth Adjustment (Fig. A, H)

1. Hold the saw firmly and loosen (clockwise) the depth adjustment lever  4  and move shoe ( 5 , Fig. A) to obtain the desired depth of cut.
2. Make sure the depth adjustment lever has been retightened (counterclockwise) before operating saw. For the most efficient cutting action, set the depth adjustment so that one‑half tooth of the blade will project below the material to be cut. This distance is from the tip of the tooth to the bottom of the gullet in front of it. This keeps blade friction at a minimum, removes sawdust from the cut, results in cooler, faster sawing and reduces the chance of kickback. A method for checking for correct cutting depth is shown in Figure H. Lay a piece of the material you plan to cut along the side of the blade, as shown, and observe how much tooth projects beyond the material.

Bevel Angle Adjustment (Fig. A, I) The full range of the bevel adjustment is from 0 ° to 50 °. The quadrant is graduated in increments of 1 °. On the front of the saw is a bevel angle adjustment mechanism consisting of a calibrated quadrant and a bevel adjustment lever  10 .

To Set the Saw for a Bevel Cut

1. Loosen (counterclockwise) the bevel adjustment lever  10  and tilt shoe ( 5 , Fig. A) to the desired angle by aligning the pointer with the desired angle mark.
2. Retighten lever firmly (clockwise).

Kerf Indicator (Fig. A)
The front of the saw shoe has a kerf indicator  9  for vertical and bevel cutting. This indicator enables you to guide the saw along cutting lines penciled on the material being cut. The kerf indicator lines up with the left (inner) side of the saw blade, which makes the slot or “kerf” cut by the moving blade fall to the right of the indicator. Guide along the penciled cutting line so that the kerf falls into the waste or surplus material.
Mounting and Adjusting the Rip Fence (Fig. M) The rip fence  26  is used for cutting parallel to the edge of the workpiece.
Mounting

1. Slacken the rip fence adjustment knob  25  to allow the rip fence to pass.
2. Insert the rip fence  26  in the base plate as shown.
3. Tighten the rip fence adjustment knob  25 .

Adjusting

1. Slacken the rip fence adjustment knob  25  and set the rip fence  26  to the desired width. The adjustment can be read on the rip fence scale.
2. Tighten the rip adjustment knob  25

Mounting the Dust Extraction Port (Fig. A, E)
Your circular saw is supplied with a dust extraction port. To Install the Dust Extraction Port

1. Fully loosen depth adjustment lever  4 .
2. Place the shoe  5  in the lowest position.
3. Push the dust extraction port  22  onto the circular saw upper guard and align with the mounting holes. Secure dust extraction port to the upper guard using the two screws 24 provided.

Prior to Operation

• Make sure the guards have been mounted correctly. The saw blade guard must be in closed position.
• Make sure the saw blade rotates in the direction of the arrow on the blade.
• Do not use excessively worn saw blades.

OPERATION

Instructions for Use
WARNING: Always observe the safety instructions and applicable regulations.
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect battery pack before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury.

Proper Hand Position (Fig. D)

WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand position as shown.
WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation of a sudden reaction. Proper hand position requires one hand on the main handle   23  and one hand on the auxilliary handle  12 .
Switching On and Off (Fig. A)
For safety reasons the trigger switch  2  of your tool is equipped with a lock‑off button  1 . Press the lock‑off button to unlock the tool. To run the tool, press the trigger switch  2 . As soon as the trigger switch is released, the lock‑off switch is automatically activated to prevent unintended starting of the machine.
NOTICE: Do not switch the tool ON or OFF when the saw blade touches the workpiece or other materials.

Rafter Hook (Fig. G)
(Included with some models)

WARNING: To reduce the risk of serious personal injury, do not use the tool’s rafter hook to hang the tool from your body. DO NOT use the rafter hook for tethering or securing the tool to a person or object during use. DO NOT suspend tool overhead or suspend objects from the rafter hook.
WARNING: To reduce the risk of injury from the circular saw falling on operators or bystanders, make sure it is supported securely when using the rafter hook, or resting in a secure and stable location when not in use. Be sure to keep the area below clear to reduce the risk of the tool or off-cut material falling and striking someone or something below. The circular saw has a convenient rafter hook  18  that allows it to hang on a suitable, stable structure between uses. The rafter hook is not for tethering or securing the tool to a person or object during use when elevated.

Worklight (Fig. A)
injury could result. The worklight  11  is activated when the trigger switch lock‑off button  1  is depressed, and will automatically turn off 20 seconds after the trigger is released. If the trigger switch  2  remains depresed, the worklight will remain on.
NOTE: The worklight is for lighting the immediate work surface and is not intended to be used as a flashlight.

Workpiece Support (Fig. D, J–L)

WARNING: It is important to support the work properly and to hold the saw firmly to prevent loss of control which could cause personal injury. Figure D illustrates proper hand support of the saw. Maintain a firm grip with both hands on the saw and position your body and arm to allow you to resist kickback if it occurs. ALWAYS TURN OFF TOOL AND REMOVE BATTERY BEFORE MAKING ANY ADJUSTMENTS! Figure K shows proper sawing position. Note that hands are kept away from cutting area. To avoid kickback, DO support board or panel NEAR the cut (Fig. J). DON’T support board or panel away from the cut (Fig. J). Place the work with its “good” side – the one on which appearance is most important – down. The saw cuts upward, so any splintering will be on the work face that is up when you cut it.
Cutting (Fig. L–N) Place the wider portion of the saw shoe on that part of the workpiece which is solidly supported, not on the section that will fall off when the cut is made. As an example, Figure K illustrates the RIGHT way to cut off the end of a board. Always clamp work. Don’t try to hold short pieces by hand! (Figure L) Remember to support cantilevered and overhanging material. Use caution when sawing material from below. Be sure saw is up to full speed before blade contacts material to be cut. Starting saw with blade against material to be cut or pushed forward into kerf can result in kickback. Push the saw forward at a speed which allows the blade to cut without laboring. Hardness and toughness can vary even in the same piece of material, and knotty or damp sections can put a heavy load on the saw. When this happens, push the saw more slowly, but hard enough to keep working without much decrease in speed. Forcing the saw can cause rough cuts, inaccuracy, kickback, and over‑heating of the motor. Should your cut begin to go off the line, don’t try to force it back on. Release the trigger switch and allow blade to come to a complete stop. Then you can withdraw the saw, sight anew, and start a new cut slightly inside the wrong one. Withdraw the saw if you must shift the cut. Forcing a correction inside the cut can stall the saw and lead to kickback.
IF SAW STALLS, RELEASE THE TRIGGER SWITCH AND BACK THE SAW UNTIL IT IS LOOSE. BE SURE BLADE IS STRAIGHT IN THE CUT AND CLEAR OF THE CUTTING EDGE BEFORE RESTARTING.
As you finish a cut, release the trigger switch and allow the blade to stop before lifting the saw from the work. As you lift the saw, the spring‑tensioned lower blade guard will automatically close under the blade. Remember the blade is exposed until this occurs. Never reach under the work for any reason. When you have to retract the lower blade guard manually (as is necessary for starting pocket cuts), always use the retracting lever.

Ripping (Fig. M) Ripping is the process of cutting wider boards into narrower strips – cutting grain lengthwise. Hand guiding is more difficult for this type of sawing and the use of a DEWALT rip fence
is recommended.
Pocket Cutting (Fig. N)

WARNING: Never tie the lower blade guard in a raised position. Never move the saw backwards when pocket cutting. This may cause the saw to raise up off the work surface, which could cause injury.

1. Adjust the saw shoe so the blade cuts at desired depth.
2. Tilt the saw forward and rest front of the shoe on material to be cut.
3. Using the lower blade guard retracting lever, retract the lower blade guard to an upward position. Lower the rear of the shoe until the blade teeth almost touch the cutting line.
4. Release the lower blade guard (its contact with the work will keep it in position to open freely as you start the cut). Remove your hand from the lower blade guard retracting lever and firmly grip the auxiliary handle  12 , as shown in Figure N. Position your body and arm to allow you to resist kickback if it occurs.
5. Make sure blade is not in contact with cutting surface before starting saw.
6. Start the motor and gradually lower the saw until its shoe rests flat on the material to be cut. Advance saw along the cutting line until cut is completed.
7. Release the trigger switch and allow the blade to stop completely before withdrawing the blade from the material.
8. When starting each new cut, repeat the above steps.

Dust Extraction (Fig. E, F)

WARNING: Risk of dust inhalation. To reduce the risk of personal injury, ALWAYS wear an approved dust mask. A dust extraction port  22  is supplied with your tool. The dust extraction port allows you to connect the tool an external dust extractor, either using the AirLock™ system (DWV9000‑XJ), or a standard 32 mm dust extractor fitment.
WARNING: ALWAYS use a vacuum extractor designed in compliance with the applicable directives regarding dust emission when sawing wood. Vacuum hoses of most common vacuum cleaners will fit directly into the dust extraction outlet.

MAINTENANCE

Your power tool has been designed to operate over a long period of time with a minimum of maintenance. Continuous satisfactory operation depends upon proper tool care and regular cleaning.
WARNING: To reduce the risk of serious personal injury, turn tool off and disconnect battery pack before making any adjustments or removing/installing attachments or accessories. An accidental start-up can cause injury.

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 into a liquid.

Lower Guard
The lower guard should always rotate and close freely from a fully open to fully closed position. Always check for correct operation before cutting by fully opening the guard and letting it close. If the guard closes slowly or not completely, it will need cleaning or servicing. Do not use the saw until it functions correctly. To clean the guard, use dry air or a soft brush to remove all accumulated sawdust or debris from the path of the guard and from around the guard spring. Should this not correct the problem, it will need to be serviced by an authorised service centre.
DO NOT USE WATER FEED ATTACHMENTS WITH THIS SAW. VISUALLY EXAMINE CARBIDE BLADES BEFORE USE. REPLACE IF DAMAGED.
