SPECIFIC SAFETY RULES

DO NOT let comfort or familiarity with
product (gained from repeated use)
replace strict adherence to circular saw
safety rules. If you use this tool unsafely
or incorrectly, you can suffer serious per-
sonal injury.
1. DANGER! Keep hands away from cutting area
and blade. Keep your second hand on auxiliary
handle, or motor housing. If both hands are hold-
ing the saw, they cannot be cut by the blade.
Keep your body positioned to 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 Kick-
back")
Do not reach underneath the work. The guard can
not protect you from the blade below the work. Do
not attempt to remove cut material when blade is
moving.
CAUTION: Blades coast after turn off. Wait until
blade stops before grasping cut material.
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 posi-
tion. If saw 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.
To check lower guard, open lower guard by hand,
then release and watch guard closure. Also check to
see that Retracting Lever does not touch tool hous-
ing. Leaving blade exposed is VERY DANGEROUS
and can lead to serious personal injury.

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 Retract-
ing Lever. As soon as blade enters the material,
lower guard must be released. For all other saw-
ing, 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 own cord. Con-
tact 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.
10. 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 of operation.
