SAFETY INSTRUCTIONS
GENERAL POWER TOOL SAFETY WARNINGS
ѥWARNING: Read all safety warnings and instructions. Failure to follow the
warnings and instructions 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.
WORK AREA SAFETY
Keep the 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.
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 ground-fault circuit interrupter (GFCI) protected power supply. Use of a
GFCI reduces the risk of electric shock.
7
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 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, clothing and gloves 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 that these are connected and properly used.
Use of these devices can reduce dust-related hazards.
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 more safely
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 the battery pack 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. 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.
8
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, 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.
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.
Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance instructions may create a risk of shock or injury.
SPECIFIC SAFETY RULES FOR CIRCULAR SAW
Safety instructions for all saws
ѥDANGER: 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.
Do not reach underneath the workpiece. The guard cannot protect you from the blade below the workpiece.
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 workpiece to a stable platform. It is important to support the work properly to minimize body exposure, blade binding, or loss of control.
Hold the power tool by the insulated gripping surfaces only when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will also make exposed
metal parts of the power tool “live”.
When ripping, always use a rip fence or straight edge guide. This improves the accuracy of cut and reduces the chance of blade binding.
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 eccentrically, causing loss of control.
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.

Kickback causes and related warnings
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 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.
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.
When the 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 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. Supports 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 blades. Unsharpened or improperly set blades produce 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 sawing into existing walls or other blind areas. The protruding blade may cut objects that can cause kickback.

Safety instructions for lower guard of saws
Check the lower guard for proper closing before each use. Do not operate the saw if the lower guard does not move freely and close instantly. Never clamp or tie the lower guard into the open position.
If the saw is accidentally dropped, the lower guard may be bent. Raise the lower guard with the retracting handle and make sure that it moves freely and does not touch the blade or any other part, in all angles and all depths of cut.
Check the operation of the lower guard spring. If the guard and the spring are not operating properly, they must be serviced before use.
The lower guard may operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
The lower 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.
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.
To avoid personal injury, do not use the circular saw to make pocket cuts.

OPERATION
SAW BLADES
The best of saw blades will not cut efciently if they are not kept clean, sharp
and properly set. Using a dull blade will place a heavy load on the saw and increase the danger of
kickback. Keep extra blades on hand, so that sharp blades are always available. Gum and wood pitch hardened on the blades will slow the saw down. Use gum
and pitch remover, hot water or kerosene to remove these accumulations. DO NOT USE GASOLINE.
ѥWARNING: A blade diameter of 7 1/4 in. is the maximum blade capacity of
your saw. A blade diameter greater than 7 1/4 in. will come in contact with the blade guards. Never use a blade that is so thick that it prevents the outer blade washer from engaging with the flat side of the spindle. Blades that are too large or too thick can result in an accident causing serious injury.
BLADE GUARD SYSTEM
The lower blade guard attached to your circular saw is there for your protection and safety. It should never be altered for any reason. If it becomes damaged or begins to return slowly or sluggishly, do not operate your saw until the blade guard has been repaired or replaced. Always leave the guard in its correct operating position when using the saw.
ѥDANGER: When sawing through a workpiece, the lower blade guard does
not cover the blade on the underside of the workpiece. Since the blade is exposed on the underside of the workpiece, keep hands and fingers away from the cutting area. Any part of your body coming in contact with a moving blade will result in serious injury.
ѥWARNING: Never use the saw when the guard is not operating properly.
The guard should be checked for correct operation before each use. If you drop your saw, check that the lower blade guard and bumper for damage at all depth settings before using.
ѥWARNING: When using the saw, always stay alert and exercise control. Do
not remove the saw from the workpiece while the blade is moving.
16
KICKBACK (Fig. 3, 4)
Kickback occurs when the blade stalls rapidly and the saw is driven back towards you. Blade stalling is caused by any action that pinches the blade in the wood. To avoid kickback, release the trigger switch immediately if the blade binds or saw stalls. Kickback could cause you to lose control of the saw.
Loss of control can lead to serious injury.
Fig. 3
KICKBACK
DIRECTION OF CUT
Correct Blade Depth
Blade is Set Too Deep
To guard against kickback, avoid dangerous practices, such as the following:
1. Setting the blade depth incorrectly.
2. Sawing into knots or nails in the workpiece.
3. Twisting the blade while making a cut.
4. Making a cut with a dull, gummed up or improperly set blade.
5. Supporting the workpiece incorrectly (Fig. 4).
6. Forcing a cut.
7. Cutting warped or wet lumber.
8. Operating the tool incorrectly or misusing the tool.
9. Attempting to cut with blade at less than full speed.
ѥWARNING: If the blade comes in contact with the workpiece before it
reaches full speed, it could cause the saw to “kickback” towards you, which could result in serious injury.
Wrong
Fig. 4
17
To lessen the chance of kickback:
1. Keep the blade at the correct depth setting. The depth setting should not exceed 1/4 in. below the material being cut (Fig. 5).
2. Inspect the workpiece for knots or nails before cutting. Never saw into a knot or nail.
3. Make straight cuts. Always use a straight edge guide (available separately) when rip cutting. This helps prevent twisting of the blade.
4. Use clean, sharp and properly set blades. Never make cuts with dull blades.
5. Support the workpiece properly before beginning a cut (Fig. 6).
6. Use steady, even pressure when making a cut. Never force a cut.
7. Do not cut warped or wet lumber.
8. Hold the saw rmly with both hands and keep your body in a balanced
position so as to resist the kickback forces if kickback should occur.
ѥWARNING: To avoid kickback, release the trigger switch immediately if the
blade binds or the saw stalls. Kickback could cause you to lose control of the saw. Loss of control can lead to serious injury.

LOCK-OFF BUTTON (Fig. 7)
The lock-off button reduces the possibility of accidental starting. The lock-off button is located on the handle above the trigger switch. The lock-off button must be depressed before you pull the trigger switch.
TRIGGER SWITCH (Fig. 7)
To turn the circular saw ON, depress the lock-off button, and then squeeze the trigger switch. Do not touch the blade to the workpiece until the saw has
reached full speed.
To turn the circular saw OFF, release the trigger switch and allow it to return to the “OFF” position.
After you release the trigger switch, allow the blade to come to a complete stop.
Do not remove the saw from the workpiece while the blade is moving.
DEPTH-OF-CUT ADJUSTMENT
Always use the correct blade-depth setting. The correct blade-depth setting for all cuts should not be more than 1/4 in. below the material being cut. Allowing more depth will increase the chance of kickback and cause the cut to be rough. Your saw is equipped with a depth-of-cut scale that provides enhanced depth­of-cut accuracy. The depth-of-cut scale is located on the inside back of the upper blade guard.
TO ADJUST BLADE DEPTH (Fig. 8)
1. Disconnect the circular saw from the power source when adjusting the depth of cut.
2. Raise the depth-of-cut adjustment lever to loosen the base.
3. Determine the desired depth of cut.
4. Locate the depth scale on the back of the upper blade guard.
5. Hold the base at against the workpiece and raise or lower the saw until the
indicator aligns with the desired depth on the depth scale.
6. Tighten the depth-of-cut adjustment lever securely by lower it down.
