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 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.
Additional Safety Instructions for
Circular Saws
• Wear ear protectors. Exposure to noise can
cause hearing loss.
• Wear a dust mask. Exposure to dust particles
can cause breathing difficulty and possible
injury.
• 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 specified in this manual, complying
with EN 847-1.
• Never use abrasive cut-off wheels .
• Ensure that the riving knife is adjusted so that
the distance between the riving knive and the
rim of the blade is not more than 5 mm, and
the rim of the blade does not extend more than
5 mm beyond the lowest edge of the riving
knife.
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.
