Further safety instructions for all saws

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.
a) 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.
b) 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.
c) 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.
d) Do not use dull or damaged blades.
Unsharpened or improperly set blades
produce narrow kerf causing excessive
friction, blade binding and kickback.
e) Blade depth and bevel adjusting locking
levers must be tight and secure before
making the cut. If blade adjustment shifts
while cutting, it may cause binding and
kickback.
f) Use extra caution when sawing into
existing walls or other blind areas. The
protruding blade may cut objects that can
cause kickback.
Safety instructions for saws with
pendulum guard
Lower guard function
a) Check the lower guard for proper
closing before each use. Do not operate
the saw if the lower guard does not
move freely and close instantly. Never
clamp or tie the lower guard into the
open position. If the saw is accidentally
dropped, the 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.
c) The lower guard may be retracted
manually only for special cuts such as
"plunge cuts" and "compound cuts".
Raise the lower guard by the retracting
handle and as soon as the blade enters
the material, the lower guard must be
released. For all other sawing, the lower guard
should operate automatically.
d) Always observe that the lower guard
is covering the blade before placing
the saw down on bench or floor. An
unprotected, coasting blade will cause the saw
to walk backwards, cutting whatever is in its
path. Be aware of the time it takes for the blade
to stop after switch is released.
Safety instructions for plunge
type saws
Guard function
a) Check the guard for proper closing
before each use. Do not operate the
saw if the guard does not move freely
and enclose the blade instantly. Never
clamp or tie the guard so that the blade
is exposed. If the saw is accidentally dropped,
the guard may be bent. Check to make sure
that the guard moves freely and does not touch
