2. Remove the blade clamping screw
washer 16 only. Remove old blade.
3. Clean any sawdust that may have accumulated in the
guard or clamp washer area and check the condition and
operation of the lower blade guard as previously outlined.
Do not lubricate this area.
4. Select the proper blade for the application (see Blades).
Always use blades that are the correct size (diameter)
with the proper size and shape center hole for mounting
on the saw spindle. Always assure that the maximum
recommended speed (rpm) on the saw blade meets or
exceeds the speed (rpm) of the saw.
5. Follow steps 2 through 6 under To Install the
Blade, making sure that the blade will rotate in the
proper direction.

Lower Blade Guard


WARNING: The lower blade guard is a safety
feature which reduces the risk of serious
personal injury. Never use the saw if the lower
blade guard is missing, damaged, misassembled
or not working properly. Do not rely on the
lower blade guard to protect you under all
circumstances. Your safety depends on following
all warnings and precautions as well as proper
operation of the saw. Check lower blade guard
for proper closing before each use as outlined
in Further safety instructions for All saws.
If the lower blade guard is missing or not
working properly, have the saw serviced before
using. To assure product safety and reliability,
repair, maintenance and adjustment should
be performed by an authorized service center
or other qualified service organization, always
using identical replacement parts.
Blades

CAUTION: Burn hazard. Do not touch the the blade
immediately after use. Contact with the blade may
result in personal injury.

WARNING: To minimize the risk of eye injury, always
use eye protection. Carbide is a hard but brittle
material. Foreign objects in the workpiece such as wire
or nails can cause tips to crack or break. Only operate
saw when proper saw blade guard is in place. Mount
blade securely in proper rotation before using, and
always use a clean, sharp blade.

Do not use abrasive wheels or blades. A dull blade will
cause slow inefficient cutting, overload on the saw motor,
excessive splintering, and could increase the possibility of
kickback. Please refer to the table below to determine the
correct size replacement blade for your model saw.

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 more likely to occur when any of the following
conditions exists.
1. improper Workpiece support
2. improper Depth Of Cut setting On saw
WARNING: Do not cut ferrous and or non-ferrous
metals (steel), masonry, glass, masonry-type planking,
cement board or tile with this saw.

a. A. Sagging or improper lifting of the cut off piece
can cause pinching of the blade and lead to kickback
(Fig. N).
b. Cutting through material supported at the outer ends
only can cause kickback. As the material weakens it
sags, closing down the kerf and pinching the blade
(Fig. N).
c. Cutting off a cantilevered or overhanging piece of
material from the bottom up in a vertical direction
can cause kickback. The falling cut off piece can pinch
the blade.
d. Cutting off long narrow strips (as in ripping) can cause
kickback. The cut off strip can sag or twist closing the
kerf and pinching the blade.
e. Snagging the lower guard on a surface below the
material being cut momentarily reduces operator
control. The saw can lift partially out of the cut
increasing the chance of blade twist.
To make the most efficient cut, the blade should protrude
only far enough to expose one-half of a tooth as shown
in Figure P. This allows the shoe to support the blade and
minimizes twisting and pinching in the material. See the
section titled Cutting Depth Adjustment.
