SERVICE
•
Tool service must be performed only by quali-
fied repair personnel. Service or maintenance
performed by unqualified personnel may result in a
risk of injury.
•
When servicing a tool, use only identical re-
placement parts. Follow instructions in the
Maintenance section of this manual. Use of
unauthorized parts or failure to follow Maintenance
Instructions may create a risk of shock or injury.
•
DANGER! Keep hands away from cutting area
and blade. Keep your second hand on the
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 "Causes and Operator Prevention
of Kickback.")
•
Do not reach underneath the work. The guard
can not protect you from the blade below the work.
•
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.
•
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.
•
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.
•
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.
•
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.
•
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 also make exposed
metal parts of the tool "live" and shock the operator.
•
When ripping always use a rip fence or straight
edge guide. This improves the accuracy of the cut
and reduces the chance for blade binding.
•
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.
•
Never use damaged or incorrect blade washers
or bolts. The blade washers and bolts were
specially designed for the saw for optimum
performance
and safety of operation.
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 the 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
KICKBACK may occur. Investigate and take
corrective actions to eliminate the cause of blade
binding.
