GENERAL POWER TOOL SAFETY WARNINGS
CIRCULAR SAW SAFETY WARNINGS

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 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.
BATTERY TOOL USE AND CARE

Recharge only with the charger specified by the
manufacturer.
A charger that is suitable for one type
of battery pack may create a risk of fire when used with
another battery pack.

Use power tools only with specifically designated
battery packs. Use of any other battery packs may create
a risk of injury and fire.

When battery pack is not in use, keep it away from
other metal objects, like paper clips, coins, keys, nails,
screws or other small metal objects, that can make a
connection from one terminal to another. Shorting the
battery terminals together may cause burns or a fire.

Under abusive conditions, liquid may be ejected from
the battery; avoid contact. If contact accidentally
occurs, flush with water. If liquid contacts eyes,
additionally seek medical help. Liquid ejected from the
battery may cause irritation or burns.
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.

When servicing a power tool, use only identical
replacement parts. 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.
CUTTING PROCEDURES
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.

Do not reach underneath the workpiece.
The guard
can not 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 insulated gripping surfaces only,
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.

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 arbour 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 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
