Further safety instructions for all saws

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.
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.
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.
g) Use extra caution when sawing into existing walls or other blind areas.
The protruding blade may cut objects that can cause kickback.

Lower guard function

a) Check lower guard for proper closing before each use. Do not operate the saw
if lower guard does not move freely and close instantly. Never clamp or tie
the lower guard into the open position. If saw is accidentally dropped, lower
guard may be bent. Raise the lower guard with the retracting handle and make sure
it moves freely and does not touch the blade or any other part, in all angles and
depths of cut.
b) Check the operation of the lower guard spring. If the guard and the spring are
not operating properly, they must be serviced before use. Lower guard may
operate sluggishly due to damaged parts, gummy deposits, or a build-up of debris.
