Lower Guard Safety Instructions
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 should 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 fl oor.
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.
Additional safety instructions for circular saws
• Wear ear protectors. Exposure to noise can
cause hearing loss.
• Preferably wear a dust mask.
• Do not use blades of larger or smaller diameter
than recommended. For the proper blade
rating refer to the technical data. Use only the
blades specifi ed in this manual, complying with
EN 847-1.
• Never use abrasive cut-off wheels.

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 instruction manual. Incorrect spacing,
positioning and alignment can make the riving
knife ineffective in preventing kickback.
c) For the riving knife to work, it must be
engaged in the work piece. The riving knife is
ineffective in preventing kickback during short
cuts.
d) Do not operate the saw if riving knife is bent.
Even a light interference can slow the closing rate
of a guard.
