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 inter-
rupting 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. Investi-
gate and take corrective actions to elimi-
nate the cause of blade binding.
c. When restarting a saw in the work-
piece, 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
6
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 lock-
ing 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.
c. Lower guard may be retracted manu-
ally only for special cuts such as
"plunge cuts" and "compound cuts".
Raise lower guard by retracting handle
and as soon as 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 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.
