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 nay 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.
f ) when ripping, always use a rip fence or straight edge guide. This
improves the accuracy 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, causing 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.

FURTHER SAFETY INSTRUCTION FOR SAW
Kickback cause 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 dowm,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 opeator.
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 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.
b ) 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.
