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 tools.
Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords
increases the risk of electric shock.
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 the
risk of personal injuries.
c) 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 energizing 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 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) 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.
h)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.
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.
f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of electric shock.

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

b) Ear damage if working without ear protection.
c) Damage to your health caused by swinging your hands and arms when operating the appliance
for longer periods of time or if the unit is not held or maintained properly.
1. Do not reach underneath the workpiece. The guard cannot protect you from the blade below
the workpiece.
2. 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.
CORDLESS CIRCULAR SAW SAFETY WARNINGS
78
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.
WARNING

910
3. Never hold the workpiece in your hands or across your
leg while cutting. 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.
4. Hold the power tool by insulated gripping surfaces, when performing an operation where
the cutting tool may contact hidden wiring.Contact with a“live" wire will also make exposed
metal parts of the power tool“live" and could givethe operator an electric shock.
5. When ripping, always use a rip fence or straight edge guide. This improves the accuracy of
cut and reduces the chance of blade binding.
6. 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 off-centre. causing loss of control.
7. 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
1. Kickback is a sudden reaction to a pinched, jammed or misaligned saw blade, causing an
uncontrolled saw to lift up and out of the workpiece toward the operator.
2. When the blade is pinched or Jammed tightly by the kerf closing down, the blade stalls and the
motor reaction drives the unit rapidly back toward the operator.
3. 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.
1. 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.
2. 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.
3. When restarting a saw in the workpiece, center the saw blade in the kerf so that the saw
teeth are not engaged into the material. If a saw blade binds, it may walk up or kickbackfrom
the workpiece as the saw is restarted.
4. 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.
5.Do not use dull or damaged blades. Unsharpenedor improperly set blades produce narrow
kerf caus-ingexcessive friction, blade binding and kickback.

11 12
6. Blade depth and bevel adjusting locking levers must be
tight and secure before making the cut. If blade adjustment
shifts while cutting, it may cause binding and kickback.
7. Use extra caution when sawing into existing walls or
other blind areas. The protruding blade may cut objects that
can cause kickback.
8. ALWAYS hold the tool firmly with both hands. NEVER
place your hand, leg or any part of your body under the
tool base or behind the saw, especially when making
cross-cuts. If kickback occurs, the saw could easily jump
backwards over your hand, leading to serious personal injury.
9. 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
5. 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.
1. 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 it moves freely and does not touch the
blade or any other part, in all angles and depths of cut.
2. 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.
3. The lower guard may be retracted manually only for special cuts such as“plunge cuts”
and“compound cuts". Raise the lower guard by the retracting handle and as soon as the
blade enters the material, the lower guard must be released. For all other sawing, the lower
guard should operate automatically.
4. Always observe that the lower guard is covering the blade before placing the 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.
ADDITIONAL SAFETY WARNINGS
1. 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.
2. Do not attempt to remove cut material when blade is
moving. Wait until blade stops before grasping cut
material. Blades coast after turn off.
3. Avoid cutting nails. Inspect for and remove all nails
from lumber before cutting.
4. 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. If the
workpiece is short or small, clamp it down. Do not try
to hold short pieces by hand!
5. Before setting the tool down after completing a cut,
be sure that the guard has closed and the blade has
come to a complete stop.
6. Never attempt to saw with the circular saw held
upside down in a vise. This is extremely dangerous and
can lead to serious accidents.

7. Some material contains chemicals which may be toxic. Take caution to prevent dust
inhalation and skin contact. Follow material supplier safety data.
8. Do not stop the blades by lateral pressure on the saw blade.
9. Do not use any abrasive wheels.
10. Only use the saw blade with the diameter that is marked on the tool or specified in the
manual. Use of an incorrectly sized blade may affect the proper guarding of the blade or guard
operation which could result in serious personal injury.
11. Keep blade sharp and clean. Gum and wood pitch hardened on blades slows saw and
increases potential for kickback. Keep blade clean by first removing it from tool, then cleaning it
with gum and pitch remover, hot water or kerosene. Never use gasoline.
12. Wear a dust mask and hearing protection when use the tool.
13. Always use the saw blade intended for cutting the material that you are going to cut.
14. Only use the saw blades that are marked with a speed equal or higher than the speed
marked
on the tool.
15. (For European countries only)
Always use the blade which conforms to EN847-1.
DO NOT let comfort or familiarity with product (gained from repeated use) replace
strict adherence to safety rules for the subject product. MISUSE or failure to follow
the safety rules stated in this instruction manual may cause serious personal injury.
