Lower guard function
16. Check lower guard for proper closing before
each use. Do not operate the tool if lower
guard does not move freely and close
instantly. Never clamp or tie the lower guard
into the open position. If tool is accidentally
dropped, lower guard may be bent. Raise the
lower guard with the retracting lever and make
sure it moves freely and does not touch the blade
or any other part, in all angles and depths of cut.
17. 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.
18. Lower guard may 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.
19. Always observe that the lower guard is
covering the blade before placing tool down on
bench or floor. An unprotected, coasting blade will
cause the tool 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.
20. To check lower guard, open lower guard by hand,
then release and watch guard closure. Also check
to see that retracting handle does not touch tool
housing. Leaving
DANGEROUS and can lead to serious personal injury.
Additional safety warnings
21. Do not stop the blades by lateral pressure on
the blade.
22. DANGER:
Do not attempt to remove cut material when
blade is moving.
CAUTION: Blades coast after turn off.
23. Place the wider portion of the tool base on that part
of the workpiece which is solidly supported, not on
the section that will fall off when the cut is made.
24. Never attempt to make a cut with the tool held
upside down in a vise. This is extremely
dangerous and can lead to serious accidents.
25. Wear safety goggles and hearing protection
during operation.
26. Always use blades recommended in this
manual. Do not use any abrasive wheels.
