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 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.
e) Hold power tool by insulated gripping surfaces 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
shock the operator.
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 eccentrically, 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 INSTRUCTIONS FOR ALL SAWS
Causes and operator prevention of kickback:
— 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.
a) Maintain
a
fi
rm grip with both hands on the saw and position your arms to resist
kickback forces.
Position your body 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.
