Specific Safety Rules
1.
DANGER! Keep hands away from cutting area and blade. Keep your second
hand on auxiliary handle, or motor housing. If both hands are holding the
saw, they cannot be cut by the blade.
Keep your body positioned t o either side of the saw blade, but not in line
with the saw blade. KICKBACK could cause the saw to jump backwards. (See
"Causes and Operator Prevention of Kickback")
Do not reach underneath the work while blade is rotating. The guard can
not protect you from the blade below the work. Don't attempt to remove cut
material when blade is moving.
CAUTION: Blades coast after turn off.
2. Check lower guard for proper closing before each use. Do not operate 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.
3.
Check the operation and condition 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 buildup of debris.
4. Lower guard should be retracted manually only for special cuts such as
"Pocket Cuts" and "Compound Cuts." Raise lower guard by Retracting
Handle. As soon as blade enters the material, lower guard must be released.
For all other sawing, the lower guard should operate automatically.
5.
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.
6.
NEVER hold piece being cut in your hands or across your leg. It is important
to support the work properly to minimize body exposure, blade binding, or
loss of control.
7.
Hold tool by insulated gripping surfaces when performing an operation where
the cutting tool may contact hidden wiring or its o w n cord. Contact with
a "live" wire will also make exposed metal parts of the tool "live" and shock
the operator.
8. When
ripping always use a rip fence or straight edge guide. This improves
the accuracy of cut and reduces the chance for blade binding.
9.
Always use blades with correct size and shape (diamond vs. round) arbor
holes. Blades that do not match the mounting hardware of the saw
will
run
eccentrically, causing loss of control.
IO.
Never use damaged or incorrect blade washers or bolts. The blade washers
and bolt were specially designed for your saw, for optimum performance and
safety or operation.
