Further safety instructions for all saws

Kickback causes and related warnings
kickback is a sudden reaction to a pinched,
u
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
u
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
u
the cut, the teeth at the back edge of the blade
can dig into the top surface of the wood caus-
ing the blade to climb out of the kerf and jump
back toward the operator.
Kickback is the result of saw misuse and/or incor-
rect operating procedures or conditions and can
be avoided by taking proper precautions as given
below.
a. 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.

(Original instructions)
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.
c. 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.
d. 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.
e. Do not use dull or damaged blades.
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and kickback.
f. Blade depth and bevel adjusting locking
levers must be tight and secure before
making cut. If blade adjustment shifts while
cutting, it may cause binding and kickback.
