CIRCULAR SAW SAFETY
Check the lower guard for proper closing before
■
each use. Do not operate sawif lower guard does
notmove 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.
Check the operation and condition 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 buildup of debris.
Lower guard should be retracted manually only
■
for special cuts such as "Pocket Cuts" and
"Compound Cuts". Raise lower guard by Retracting
Handle. As soon as blade enters the material, lower
guard must be released. For all other sawing, the
lower guard should operate automatically.
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.
Do not use blades which are deforemed or cracked;
■
Do not use saw blades made of high speed steel;
■
Do not use blades which do not comply with
■
characteristics specified in these instructions;
Do not stop the blade by lateral pressure on the disc;
■
Ensure that movable guards, operate freely without
■
jamming;
Do not lock the movable guard in the open position;
■
Ensure that any retraction mechanism of the guard
■
system operates correctly;
Do not use saw blades the body of which is thicker or
■
set of which is smaller than the thickness of the
riving knife.
SAFETY INTRUCTIONS FOR CIRCULAR SAW
WITH RIVING KNIFE
Use the appropriate riving knife for the blade
■
being used. For the riving knife to work, it must be
thicker than the body of the blade but thinner than the
tooth set of the blade.

English
Adjust the riving knife as described in this
■
instruction manual. Incorrect spacing, positioning
and alignment can make the riving knife ineffective
in preventing kickback.
Riving knife causes interference during plunge cutting
■
and can create kickback.
For the riving knife to work, it must be engaged in
■
the workpiece. The riving knife is ineffective in
preventing kickback during short cuts.
Do not operate the saw if riving knife is bent. Event a
■
light interference can slow the closing rate of a guard
CAUSE OF KICKBACK
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 a result of tool misuse and/or
■
incorrect operating procedures or conditions and
can be avoided by taking proper precaution as
given below.
PREVENTION OF KICKBACK
Maintain a firm grip with both hands on the saw
■
and position you arms to resist kickback forces.
Position your body to either side of the blade,
but not in lime 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.
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.
When restarting a saw in the workpiece, center
■
the saw blade in the kerf and check that 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.
