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
personal 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 holding 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
Prevention of Kickback")
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 position. 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
housing. 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
Retracting Lever. 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

"Causes and Operator
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.
Contact with a "live" wire will 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 versus round) of arbour holes.
Blades that do not match the mounting hardware
of the saw will run eccentrically, causing loss of
control.
10. Never use
washers or bolts. The blade washers and bolt
were specially designed for your saw, for optimum
performance and safety of operation.
11. Causes and Operator Prevention of Kickback:
Kickback is a sudden reaction to a pinched, bound
or misaligned saw blade, causing an uncontrolled
saw to lift up and out of the workpiece toward the
operator.
When the blade is pinched or bound tightly by the
kerf closing down, the blade stalls and the motor
reaction drives the unit rapidly back toward the
operator.
If the blade becomes twisted or misaligned in the
cut, the teeth at the back edge of the blade can
dig into the top surface of the wood causing the
blade to climb out of the kerf and jump back
toward operator.
Kickback is the result of tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below:
Maintain a firm grip with both hands on the saw
and position your body and arm to allow you to
resist KICKBACK forces. KICKBACK forces can
be controlled by the operator, if proper precautions
are taken.
When blade is binding, or when interrupting a
cut for any reason, release the trigger and hold
the saw motionless in the material until the
blade comes to a complete stop. Never attempt
to remove the saw from the work or pull the
saw backward while the blade is in motion or
