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.
Always leave the guard in its correct operating
position when using the saw.
Lower Blade Guard
retracts automatically
when cut is being
made
DANGER: When sawing through a work-
piece, the lower blade guard does not cover
the blade on the underside of the workpiece.
Keep hands and fingers away from the cutting
area. If any part of your body comes in con-
tact with the moving blade, serious injury will
result.
CAUTION: Never use the saw when the lower
blade guard is not operating properly. The low-
er 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 before 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
URREA Repair Center for service before using it.

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.
• Kickback can result from tool misuse and/or
incorrect operating procedures or conditions.
HOW TO PREVENT KICKBACK
DANGER: Always release the trigger switch
immediately if the blade binds or the saw stalls.
Kickback could cause you to lose control of the
saw. Loss of control can lead to serious injury.
1. Always maintain a
firm grip with both
hands on the saw and
position your body
and arms to allow
you to resist kickback
forces.
The operator can control kickback forces if the
proper precautions are taken.
2. If the blade is binding or when you are in-
terrupting a cut for any reason, always 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 workpiece or pull the saw backward while
the blade is in motion, or kickback may occur.
Check and take corrective action to eliminate
the cause of blade binding.
3. Inspect the workpiece for knots or nails be-
fore cutting. Never saw into a knot or nail.
4. Do not cut warped or wet lumber.
