CIRCULAR SAW SAFETY
WARNINGS
Cutting procedures
1.
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.
2.
Do not reach underneath the workpiece. The
guard cannot protect you from the blade below the
workpiece.
3.
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.
4.
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.
A typical illustration of proper hand support, workpiece
support, and supply cord routing (if applicable).

5.
Hold the power tool by 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"
and could give the operator an electric shock.
6.
When ripping, always use a rip fence or
straight edge guide. This improves the accuracy
of cut and reduces the chance of blade binding.
7.
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.
8.
Never
use
damaged
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;
−
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.
9.
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.
10. 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.
11.
When restarting a saw in the workpiece, centre
the saw blade in the kerf and check that saw
teeth are not engaged into the material. If saw
blade is binding, it may walk up or kickback from
the workpiece as the saw is restarted.
12. Support large panels to minimise the risk of
blade pinching and kickback. Large panels tend
to sag under their own weight. Supports must be
placed under the panel on both sides, near the line
of cut and near the edge of the panel.
To avoid kickback, do support
board or panel near the cut.
