▶ 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.
▶ 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.
▶ 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 arbour holes. Blades that do not match the mounting hardware
of the saw will run off-centre, 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, 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.
▶ 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 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.
▶ 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 kickback from the workpiece as the saw is
restarted.
