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 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.
USE PROPER EXTENSION CORD. Make sure your
extension cord is in good condition. When using an
extension cord, be sure to use one heavy enough to
carry the current your product will draw. An undersized
cord will cause a drop in line voltage resulting in loss of
power and overheating. Table 1 shows the correct size
to use depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gage. The
smaller the gage number, the heavier the cord.

CIRCULAR SAW SAFETY
WARNINGS
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 piece being cut in your hands or
across your leg. Secure the workpiece to a
stable platform. It is important to support the

4
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).
000157
5. Hold the power tool by 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"
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 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.
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.
9. 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.
10.
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.
11.
When restarting a saw in the workpiece, centre
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.
12. 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.
To avoid kickback, do support
board or panel near the cut.
000154
Do not support board or
panel away from the cut.
000156
13. Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and kickback.
14. 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.

5
15. Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
16. ALWAYS hold the tool firmly with both hands.
NEVER place your hand or fingers behind the
saw. If kickback occurs, the saw could easily
jump backwards over your hand, leading to
serious personal injury.
000194
17. Never force the saw. Push the saw forward at
a speed so that the blade cuts without
slowing. Forcing the saw can cause uneven cuts,
loss of accuracy, and possible kickback.
Lower guard function
18. Check 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. 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.
19.
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.
20. Lower guard should be retracted manually
only for special cuts such as "plunge cuts"
and "compound cuts". Raise lower guard by
retracting 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.
21. 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.
22. To check lower guard, open lower guard by
hand, then release and watch guard closure.
Also check to see that retracting handle does
not touch tool housing. Leaving blade exposed
is VERY DANGEROUS and can lead to serious
personal injury.
Additional safety warnings
23. Intended use
This tool is intended to cut wood products
only. Accumulated sawdust on the lower guard
and hub from other materials may effect the
proper closure of the lower guard which could
lead to serious personal injury.
24. Use extra caution when cutting damp wood,
pressure treated lumber, or wood containing
knots. Maintain smooth advancement of tool
without decrease in blade speed to avoid
overheating the blade tips.
25. Do not attempt to remove cut material when
blade is moving. Wait until blade stops before
grasping cut material.Blades coast after turn off.
26. Avoid Cutting Nails. Inspect for and remove
all nails from lumber before cutting.
27. Place the wider portion of the saw base on
that part of the workpiece which is solidly
supported, not on the section that will fall off
when the cut is made. As examples, Fig. 1
illustrates the RIGHT way to cut off the end of
a board, and Fig. 2 the WRONG way. If the
workpiece is short or small, clamp it down.
DO NOT TRY TO HOLD SHORT PIECES BY
HAND!
