• Never
h old 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 the 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".
= 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 arbor 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.
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. The kerf is the notch in the workpiece made by the blade as it
cuts through.
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 the 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.
