SAFETY INSTRUCTIONS FOR ALL SAWS-CUTTING PROCEDURES
DANGER! Keep hands away from cutting area and the blade. If both hands are hold-
a)
ing the saw, they cannot be cut by the blade.
b) Do not reach underneath the workpiece. The guard cannot protect you from the blade
below the workpiece.
c) 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.
d) 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 minimise
body exposure, blade binding, or loss of control.
e) 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 .
f)
When ripping, always use a rip fence or straight edge guide. This improves the accu-
racy of cut and reduces the chance of blade binding.
g) 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 off-centre, caus-
ing loss of control.
h) 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, jammed 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 jammed 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.
a) Maintain a firm grip 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 opera-
tor, if proper precautions are taken.
b) When blade is binding, or when interrupting a cut for any reason, release the trig-
ger 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.
c) When restarting a saw in the workpiece, centre 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 kick-
back
from the workpiece as the saw is restarted.
d) Support large panels to minimise the risk of blade pinching and kickback. Large
