blade wrench (screw has right-hand threads and must be
turned counterclockwise to loosen).
2. Remove the blade clamping screw
washer 23 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 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 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.
Checking the Lower Guard (Fig. A)
1. Turn tool off and disconnect from power supply.
2. Rotate the lower blade guard retracting lever
fully 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 direction before using,
and always use a clean, sharp blade.

8 and outer clamp 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

dealer or authorized service center.
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.

a. Sagging or improper lifting of the cut off piece can
cause pinching of the blade and lead to kickback.
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.
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.
