hidden wiring. 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.

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) Maintain a firm grip 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
20V Cordless Brushless Circular saw
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
CIRCULAR SAW WITH INNER
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 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.
