with the blade wrench (screw has right-hand threads and
must be turned counterclockwise to loosen).
2. Remove the blade clamping screw
washer 15 . 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 (refer to 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 1 through 5 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 that
reduces the risk of serious personal injury. Never use the
saw if the lower 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 the lower blade
guard for proper closing before each use. 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.
Checking the Lower Guard (Fig. A)
1. Turn tool off and disconnect from power supply.
2. Rotate the lower guard lever (Fig. A,
closed position to the fully open position.
3. Release the lever and observe the guard
fully closed position.
The tool should be serviced by a qualified service center if it:
• fails to return to the fully closed position,
• moves intermittently or slowly, or
• contacts the blade or any part of the tool in all angles and
depth of cut.
Blades

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.

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
material 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.

a. Sagging or improper lifting of the cut off piece can cause
pinching of the blade and lead to kickback (Fig. X).
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. X).
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 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 a tooth as shown in figure H. This
allows the shoe to support the blade and minimizes twisting
and pinching in the material. See the section titled Depth of
Cut Adjustment.
a. Pushing harder to cut can cause the blade to twist.
b. Trying to turn the saw in the cut (trying to get back on
the marked line) can cause blade twist.
c. Overreaching or operating the saw with poor body
control (out of balance), can result in twisting the blade.
d. Changing hand grip or body position while cutting can
result in blade twist.
e. Backing up the saw to clear blade can lead to twist.
Dull blades cause increased loading of the saw. To
compensate, an operator will usually push harder which
