2.2 Safety instructions for all saws

Cutting procedures
DANGER: Keep hands away from cutting area and the blade. Keep
▶
your second hand on auxiliary handle or motor housing. If both hands
are holding the saw, they cannot be cut by the blade.
▶ Do not reach underneath the workpiece. The guard cannot protect you
from the blade below the workpiece.
▶ 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.
▶ 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.
