3. Do not discard the packing material until
you have carefully inspected and satisfactorily
operated the tool.
4. If any parts are damaged or missing, return
the product for replacement.
WARNING: If any parts are broken or miss-
ing, DO NOT attempt to plug in the power cord
or operate the saw until the broken or missing
parts are replaced. Failure to do so could result
in possibly serious injury.
WARNING: Do not attempt to modify this
saw or create accessories not recommended for
use with this saw. Any such alteration or modi-
fication is misuse and could result in a hazard-
ous condition leading to possibly serious injury.
WARNING: To prevent accidental starting
that could cause serious personal injury, always
disconnect the tool from the power source
when assembling parts.

OPERATION INSTRUCTIONS

WARNING: The maximum blade capacity of
your saw is 7-1/4 inches. Any blade larger than
7-1/4 inch will come in contact with the blade
guards. Never use a blade that is so thick that it
prevents the outer blade washer from engag-
ing with the flat side of the spindle. Blades that
are too large or too thick can result in an ac-
cident causing serious injury.
SAW BLADES
All saw blades need to be kept clean, sharp,
and properly set in order to cut efficiently. Us-
ing a dull blade places a heavy load on the saw
and increases the danger of kickback. Keep ex-
tra blades on hand, so sharp blades are always
available.
Gum and wood pitch that have hardened on
the blade will slow the saw. Use gum and pitch
remover, hot water, or kerosene to remove
these substances. Do not use gasoline.
BLADE GUARD SYSTEM
The lower blade guard is there for your pro-
tection and safety. It should never be altered
for any reason. If the lower blade guard be-
comes damaged or begins to return slowly or
sluggishly, do not operate your saw until the
damaged part has been repaired or replaced.
16
Always leave the guard in its correct operating
position when using the saw.
CAUTION: Never use the saw when the
lower blade guard is not operating properly.
The lower blade guard should be checked for
correct operation before each use. If you drop
your saw, check the lower blade guard and
bumper for damage at all depth settings be-
fore using.
NOTE: The lower blade guard is operating
properly when it moves freely and then readily
returns to the closed position. If, for any rea-
son, your lower blade guard and bumper do
not close freely, take the saw to your nearest
Service Center for service before using it.
Lower Blade Guard
retracts automatically
when cut is being
made.
KICKBACK
KICKBACK CAUSES
• Kickback is a sudden reaction to a pinched,
bound, or misaligned saw blade, which can
cause the saw to lift up and out of the work-
piece and 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
towards the operator.
• If the blade becomes twisted or misaligned in
the cut, the teeth at the rear edge of the blade
can dig into the top surface of the wood.
This causes the blade to climb out of the kerf
and jump back towards the operator.
• Sawing into knots or nails in the workpiece
can cause kickback.
• Sawing into wet or warped lumber can cause
kickback.
• Forcing a cut, or not supporting the work-
piece correctly can cause kickback.
Lower Blade Guard
level is in UP position
when making a cut.
1/4" or less of the Blade is
exposed on the underside
of the workpiece.
