e) Do not use dull or damaged blades. Unsharpened or
improperly set blades produce narrow kerf causing
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.
g) Use extra caution when making aplunge cutinto
existing walls or other blind areas. The protruding
blade may cut objects that can cause kickback.
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 asplunge cuts” andcompound

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
