e) Hold the power tool by insulated gripping
surfaces only, when performing an
operation where the cutting tool may
contact 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 arbor
holes.
Blades that do not match the mounting
hardware of the saw will run eccentrically,
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,
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
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,
center 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 minimize 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 CIRCULAR SAW WITH
INNER PENDULUM GUARD
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 manually
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.
