Lower guard function
▶ Check the lower guard for proper closing before each use. Do not
operate the saw if the lower guard does not move freely and close
instantly. Never clamp or tie the lower guard into the open position.
If the saw is accidentally dropped, the 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 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.
▶ The lower guard may be retracted manually only for special cuts
such as "plunge cuts" and "compound cuts". Raise the lower guard
by the retracting handle and as soon as the blade enters the material,
the 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 the 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.
Guard function

If the saw is accidentally dropped, the guard may be bent. Check to
make sure that the guard 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 guard return spring. If
the guard and the spring are not operating properly, they must be
serviced before use. The guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
▶ Assure that the base plate of the saw will not shift while performing
a "plunge cut". Blade shifting sideways will cause binding and likely
kick back.
▶ Always observe that the guard is covering the blade before placing
the 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 the switch is released.
Riving knife function
▶ Use the appropriate saw blade for the riving knife. For the riving knife
to function, the body of the blade must be thinner than the riving knife
