saw teeth are not engaged into the material.
If saw blade binds, 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.
Safety Instructions for Saws with a
Pendulum Blade Guard
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 should be retracted
manually only for special cuts such as
“plunge cuts” and “compound cuts”. Raise
the 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 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.
exposed metal parts of the power tool “live” and
could give the operator an electric shock.
f) When ripping always use a rip fence or
straight edge guide. This improves the
accuracy of cut and reduces the chance of
blade binding.
g) 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 off-centre, causing
loss of control.
h) Never use damaged or incorrect blade
washers or bolt. The blade washers and
bolt were specially designed for your saw, for
optimum performance and safety of operation.
Causes and Operator Prevention
of Kickback
– 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) 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 so that the
