GENERAL SAFETY INSTRUCTIONS
WARNING! Read all instructions. Failure to follow all
instructions listed below may result in electric shock, fire and/or serious injury. The term “power tool” in all of the warnings listed below refers to your mains operated (corded) power tool or battery operated (cordless) power tool.
SAVE THESE INSTRUCTIONS
1. WORK AREA
a. Keep work area clean and well lit. Cluttered and 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.
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 safety equipment. Always wear eye protection. Safety equipment such
as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c. Avoid accidental starting. Ensure the switch is in the off-position before
plugging in. Carrying power tools with your finger on the switch or plugging
in 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,
clothing and gloves away from moving parts. Loose clothes, jewellery 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.
Use of these devices can reduce dustrelated hazards.
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 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. Check for misalignment or binding of moving parts,
breakage of parts and any other condition that may affect the power tools 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 and in the manner intended for the particular type of power tool, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from intended could
result in a hazardous situation.
5) BATTERY TOOL USE AND CARE a. Ensure the switch is in the off position before inserting battery pack.
Inserting the battery pack into power tools that have the switch on invites accidents.
b. 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.
c. Use power tools only with specifically designated battery packs. Use of any
other battery packs may create a risk of injury and fire.
d. 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.
e. 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.
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.
Additional Safety Instructions For Australia And New Zealand
a. Young children and the infirm. This appliance is not intended for use by young
children or infirm persons without supervision. Young children should be super­vised to ensure that they do not play with this appliance.
b. Replacement of the supply cord. If the supply cord is damaged, it must be
replaced by the manufacturer or an authorised DEWALT Service Centre in order to avoid a hazard.
Additional Safety Rules for Circular Saws
DANGER: Keep hands away from cutting area and 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.
Keep your body positioned to either side of the blade, but not in line with the saw blade. KICKBACK could cause the saw to jump backwards (see KICKBACK).
Do not reach underneath the work. The guard can not protect you from the blade below the work.
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.
Never hold piece being cut in your hands or across your leg. Secure the work piece to a stable platform. It is important to suppor t the work properly to minimize body exposure, blade binding, or loss of control.
Check lower guard for proper closing before use. Do not operate saw if lower
guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position. 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.
Check the operation and condition 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 buildup of debris.
Lower guard should be retracted manually only for special cuts such as
“Pocket Cuts” and “Compound Cuts.” Raise lower guard by Retracting Handle. As soon as blade enters the material, lower guard must be released.
For all other sawing, the lower guard should operate automatically.
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.
• Hold tool by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring. Contact with a “live” wire will make
exposed metal parts of the tool “live” and shock the operator.
When ripping always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance for blade binding.
Always use blades with correct size and shape (diamond vs. round) arbor holes. Blades that do not match the mounting hardware of the saw will run eccentrically, causing loss of control.
Never use damaged or incorrect blade washers or bolts. The blade washers and bolt were specially designed for your saw, for optimum performance and safety of operation.
Avoid cutting nails. Inspect for and remove all nails from lumber before cutting.
CAUSES AND OPERATOR PREVENTION OF KICKBACK
• Kickback is a sudden reaction to a pinched, bound 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 bound 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 operator.
• Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:
Maintain a firm grip with both hands on the saw and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken.
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.
When restarting a saw in the workpiece, center the saw blade in the kerf and check that the saw teeth are not engaged into the material. If saw blade is binding, it may walk up or kickback from the workpiece as the saw is restarted.
Support large panels to minimize the risk of blade pinching and kickback. Large panels tend to sag under their own weight. Support must be placed under the panel on both sides, near the line of cut and near the edge of the panel.
Do not use dull or damaged blade. Unsharpened or improperly set blades pro- duce narrow kerf causing excessive friction, blade binding, and kickback.
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.
Use extra caution when making a “Pocket Cut” into existing walls or other
blind areas. The protruding blade may cut objects that can cause kickback.
WARNING: ALWAYS USE SAFETY GLASSES. Everyday eyeglasses are NOT safety
glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
