FURTHER SAFETY INSTRUCTIONS FOR ALL SAWS

DANGER!
a) Keep hands away from cutting area and do not reach underneath the
workpiece. Contact with the wheel will result in injury.
b) Adjust the cutting depth to the thickness of the workpiece.
c) 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, wheel binding,
or loss of control.
d) Never use damaged or incorrect wheel washers or bolt.
The wheel washers and bolt were specially designed for your saw, for optimum
performance and safety of operation.
Causes and operator prevention of kickback:
– kickback is a sudden reaction to a pinched, bound or misaligned wheel, causing an
uncontrolled saw to lift up and out of the workpiece toward the operator.
– when the wheel is pinched or bound tightly by the kerf closing down, the wheel
stalls and the motor reaction drives the unit rapidly 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 either side of the wheel, but not in line with the wheel.
Kickback could cause the saw to jump backwards, but kickback forces can be controlled
by the operator, if proper precautions are taken.
