GENERAL POWER TOOL 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.
CIRCULAR SAW SAFETY WARNINGS
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 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.
 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.
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.
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
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 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.
 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.
