e) Hold the power tool by insulated
gripping surfaces, when performing
an operation where the cutting tool
may contact hidden wiring or its own
cord. Contact with a “live” wire will also
make 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.

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) 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 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.
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 the 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
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
