RULES FOR SAFE OPERATION
KNOW YOUR TOOL
Before operating this tool, carefully read this operating manual and all of the labels affixed to
the circular saw. Keep this manual available for future reference.
IMPORTANT
This tool should only be serviced by a qualified service technician.
READ ALL INSTRUCTIONS THOROUGHLY
GENERAL SAFETY PRECAUTIONS
Keep your work area clean and well-lit. Cluttered benches and dark areas invite
accidents.
Do not operate power tools in an explosive atmosphere, such as in the presence of
flammable liquids, gases, or dust. Power tools create sparks, which may ignite the dust or
fumes.
Keep bystanders, children, and visitors away while operating a power tool. Distractions
can cause you to lose control.
Use clamps or other practical means to secure and support the workpiece to a stable
platform. Holding the work in your hand or against your body is not stable, and may lead to
loss of control.
Do not force the tool. Use the correct tool for your application. The correct tool will do
the job better and safer, at the speed that it is designed to work at.
Do not use tool if it cannot be turned on or off using the switch. Any tool that cannot be
controlled using the switch is dangerous, and must be repaired.
Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing the tool. Such preventive safety measures reduce the risk of
starting the tool accidentally.
When not in use, store tools out of the reach of children and other untrained persons.
Tools are dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools,
with sharp cutting edges are less likely to bind, and are easier to control.
Check for misalignment or binding of moving parts, broken parts, and any other
condition that may affect the operation of the tool. If it is damaged, have the tool
serviced before using. Many accidents are caused by poorly maintained tools.
Use only accessories that are recommended for your model by the manufacturer.
Accessories that may be suitable for one tool may become hazardous when used on another
tool.
Do not alter or misuse the tool. These tools are precision-built. Any non-specified
alteration or modification is considered to be misuse, and may result in a dangerous
condition.
CAUTION: Do not attempt to operate this tool until you have thoroughly read all
instructions, safety rules, and warnings. Failure to comply may result in fire, electric shock,
or serious personal injury. Save the Operating Manual, and review it frequently for reference.

WARNING: When using power tools, basic safety precautions should always be
followed in order to reduce the risk of fire, electric shock, and personal injury.
Stay alert, watch what you are doing, and use common sense when operating a power
tool. Do not use the tool when you are tired or under the influence of drugs, alcohol,
or medication. A moment of inattention while operating a power tool could result in serious
personal injury.
Dress properly. Do not wear loose clothing or jewellery. Contain long hair. Keep your
hair, clothing, and gloves away from moving parts. Loose clothes, jewellery, or long hair
can be caught in moving parts.
Avoid accidental starting. Be sure switch is in the off position before plugging the tool
in. Carrying tools with your finger on the switch, or plugging in tools when the switch is in the
on position invites accidents.
Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance allows for better control of the tool in unexpected situations.
Use safety equipment. Always wear eye protection. A dust mask, non-skid safety shoes,
a hardhat, or hearing protection must be used for appropriate conditions.
Before connecting the tool to a power source (receptacle, outlet, etc.), verify that the
voltage supplied is the same as that specified on the tool’s nameplate. A power source with
voltage that is greater than that specified for the tool can result in serious injury to the user
and damage to the tool.
WARNING: The operation of any tool can result in foreign objects being
propelled into your eyes, which could result in severe eye damage. When operating power
tool, always wear safety goggles or safety glasses with side shields, or a full face shield if
necessary.
WARNING: Remove adjusting keys or switches before turning the tool on. A wrench
or a key that is left attached to a rotating part of the tool could result in personal injury.
WARNING: If any parts are missing, do not operate the tool until the missing parts have
been replaced. Doing so could result in serious personal injury.
ELECTRICAL SAFETY
•Double insulated tools are equipped with a polarized
plug (one blade is wider than the other). This plug will fit
into a polarized outlet only one way. If the plug does not
fit into the outlet, reverse the plug. If it still does not fit,
contact a qualified electrician to install a proper outlet.
•Avoid contact with grounded surfaces such as pipes,
radiators, ranges, and refrigerators. There is an increased
risk of electric shock if your body is grounded.
•Don’t expose power tools to rain or wet conditions. A wet power tool will increase the
risk of electric shock.
•Do not abuse the cord. Never use the cord to carry the tool or to pull the plug out
of an outlet. Keep the cord away from heat, oil, sharp edges, and moving parts.
Replace damaged cords immediately. Damaged cords increase the risk of electric
shock.
•When operating a power tool outdoors, use an outdoor extension cord marked
Fig.1

4
“W-A” or “W”. These cords are rated for outdoor use, and reduce the risk of electric
shock.
•Replace damaged cords immediately. Use of damaged cords can lead to shocks, burns,
or electrocution.
•If an extension cord is required, use a cord with the proper size of conductors in order to
prevent excessive voltage drop, loss of power, or overheating. The following table shows
the correct size to use, depending on cord length and nameplate amperage rating of the
tool. When in doubt, use the next heavier gauge. Always use UL and CSA listed
extension cords.

ADDITIONAL SAFETY RULES FOR LASER LIGHTS
The laser light/laser radiation used in this system is Class III, with maximum 5 mW
and wavelengths of 400 nm-700 nm. Under normal circumstances, these lasers do not
present an optical hazard, but staring at the beam may cause flash blindness.
WARNING: Do not stare directly at the laser beam.
A hazard may exist if you deliberately stare into the beam. Please observe all of the
following safety rules:
•The laser must be used and maintained in accordance with the manufacturer’s
instructions.
•Never aim the beam at any person or any object other than the workpiece.
•The laser beam must not be deliberately aimed at any person, and must be prevented
from being directed toward the eye of any person for longer than 0.25 s.
•Always ensure that the laser beam is aimed at a sturdy workpiece that does not have
reflective surfaces. Wood and rough coated surfaces are acceptable. Bright, shiny
reflective sheet steel or similar materials are not suitable for laser use, because the
reflective surface could direct the beam back at the operator.
•Do not replace the laser light assembly with a different type. Repairs must be carried out
by the laser manufacturer, or by an authorized agent.

CAUTION: Using controls or adjustments or performing procedures other than those
specified herein may result in hazardous radiation exposure.
SPECIFIC SAFETY RULES FOR CIRCULAR SAW
WARNING: Keep your hands away from the cutting area and the blade. Keep your
second hand on the auxiliary handle or the 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 saw blade, but not in line with the
saw blade. KICKBACK could cause the saw to jump backwards.
•Do not reach underneath the work. The guard cannot protect you from the blade
below the work.
•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 in 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 it moves
freely and does not touch the blade or any other part in all angles and cutting depths.
•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. The lower
guard may operate sluggishly due to damaged parts, gummy deposits, or a buildup of
debris.
•The lower guard should only be retracted manually for special cuts, such as
“pocket cuts” and “compound cuts”. Raise the lower guard by retracting the
handle. As soon as the blade enters the material, the lower guard must be released.
The lower guard should operate automatically for all other sawing operations.
•Always verify that the lower guard is covering the blade before placing the saw
down on a bench or the floor. An unprotected coasting blade will cause the saw to
walk backward, cutting whatever is in its path. Be aware of the time it takes for the blade
to stop after the trigger is released.
•NEVER hold the piece that is being cut in your hands or across your leg. It is
important to support the work properly in order to minimize body exposure, blade binding,
or loss of control.
•Hold the tool by the insulated gripping surfaces 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 tool “live”, and shock the operator.
•When ripping, always use a rip fence or a straight edge guide. This improves the
accuracy of the cut, and reduces the chance of blade binding.
•Always use blades that have the correct size and shape arbor holes (diamond vs.
round). Blades that do not match the mounting hardware of the saw will run eccentrically,
which may cause loss of control.
•Never use damaged or incorrect blade washers or bolts. The blade washers and
bolts were designed specifically for your saw for optimum performance and safety of
operation.
•Maintain a firm grip on the saw with both hands, 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.
•If the blade is binding, or if you must interrupt a cut for any reason, release the
trigger and hold the saw motionless, with the blade in the material, until the blade

6
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, centre the saw blade in the kerf, and
verify that the saw teeth are not in contact with the material. If the saw blade is
binding, it may walk up or KICKBACK from the workpiece when the saw is restarted.
•Support large panels in such a way as 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 cutting line, and near the edge of the panel.
•Do not use a dull or damaged blade. Unsharpened or improperly set blades produce
narrow kerfs, which cause excessive friction, blade binding, and KICKBACK.
•Blade depth and bevel adjusting locking levers must be tight and secure before
making a cut. If the 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.
•Do not use blades made of high-alloy, high-speed steel (HSS).
•Do not use the circular saw near fumes or combustible liquids.
•Secure small pieces of wood firmly before working. Never hold them in your hand.
•Never slow the blade down with your hands, or by applying pressure to the side of
the blade.
•Never apply force! Move the circular saw forward gently and steadily.
