ing 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.

protruding blade may cut objects that can cause
kickback.
5.2.3 Safety instructions for circular saws with
dual-actuation of lower blade guard or
with trailing guard
a) Checklowerguard for properclosing before each
use. Do not operate the saw if lower guard does
notm ove freelyand closeinstantly. Neverclamp
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
handleand makesure itmoves freely anddoes 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 prop-
erly, 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 should be retracted manually only
forspecial cutssuch as “plunge cuts”and “com-
pound cuts.” Raise lower guard by retracting
handle and as soon as blade enters the ma-
terial, the lower guard must be released. For
all other sawing, the lower guard should operate
automatically.
d) Always observe that the guard is covering the
bladebeforeplacingsawdownonbenchor
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.
5.2.4 Additional safety instructions for all saws
with riving knife
a) 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.
b) Adjust the riving knife as described in this in-
struction manual. Incorrect spacing, positioning
and alignment can make the riving knifeineffective
in preventing kickback.
c) Always use the riving knife except when plunge
cutting. Rivingknifemust bereplaced after plunge
cutting. Riving knife causes interference during
plunge cutting and can create kickback.
d) For the riving knife to work, it must be engaged
in the workpiece. The riving knife is ineffective in
preventing kickback during short cuts.
e) Do not operate the saw if riving knife is bent.
Even a light interference can slow the closing rate
of a guard.
5.2.5 Personal safety
a) Wear earprotectors. Exposureto noise can cause
hearing loss.
b) Always hold the power tool securely with both
hands onthe grips provided. Keep the grips dry,
clean and free from oil and grease.
c) Breathing protection must be worn if the power
tool is used without a dust extraction system for
work that creates dust.
d) Do not operate the power tool without the pro-
tective devices that belong to it.
e) Operate the power tool only as intended and
when it is in faultless condition.
f) Improve the blood circulation in your fingers by
relaxing your hands and exercising your fingers
during breaks between working.
g) Switch the power tool on only after bringing it
into position at the workpiece.
h) Removethebatterybeforestoringortransporting
the power tool.
i) Always guide the power tool away from your
body when working with it.
j) Do not work with the power tool overhead.
k) Do not attempt to brake the speed of the saw
bladebypressingittotheside.
l) Do not touch the clamping flange or the flange
screw while the power tool is running.
m)The kerf mustbe free of obstructions. Donot saw
into screws and nails etc.
n) Never press the drive spindle lockbutton while
the saw blade is rotating.
o) Never direct the power tool toward persons.
p) Adjust the pressureapplied to the saw blade and
the material being cut so that the blade doesn’t
