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 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 Always use the riving knife except when plunge
cutting. Riving knife must be replaced 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.
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.
