General Power Tool Safety
Warnings

WARNING Read all safety warnings and all

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

1. Keep work area clean and well lit. Cluttered or
dark areas invite accidents.

2. 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.

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

Electrical Safety

4. 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.

5. 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.

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

7. 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.

8. 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.

9. If operating a power tool in a damp location is

unavoidable, use a ground fault circuit
interrupter (GFCI) protected supply. Use of an

GFCI reduces the risk of electric shock.

Personal Safety

10. 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.

11. 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.

12. 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.

13. 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.

14. Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.

15. 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.

16. 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.

Power tool use and care

17. 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.

18. 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.

19. 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.

20. 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.

21. Maintain power tools. Check for misalignment

or binding of moving parts, breakage of parts

3

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.

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

23. 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.

SERVICE

24. 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.

25. Follow instruction for lubricating and

changing accessories.

26. Keep handles dry, clean and free from oil and
grease.

SPECIFIC SAFETY RULES

DO NOT let comfort or familiarity with product
(gained from repeated use) replace strict adherence
to circular saw safety rules. If you use this tool
unsafely or incorrectly, you can suffer serious
personal injury.
Danger:

1. 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. Do not attempt to remove cut material
when blade is moving.
CAUTION: Blades coast after turn off. Wait until
blade stops before grasping cut material.

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 piece being cut in your hands or

across your leg. Secure the workpiece to
stable platform. It is important to support the

work properly to minimize body exposure, blade
binding, or loss of control.

A typical illustration of proper hand support, workpiece
support, and supply cord routing (if applicable).

5. Hold power tool by 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 power tool "live"
and shock the operator.

6. When ripping always use a rip fence or
straight edge guide. This improves the accuracy
cut and reduces the chance of blade binding.

7. Always use blades with correct size and shape
(diamond versus round) of arbour holes.
Blades that do not match the mounting hardware
of the saw will run eccentrically, 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.

9. 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 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
