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 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 guard for proper closing before each use as
outlined in Additional Safety Rules for Circular 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
WARNING: To minimize the risk of eye injury, always use eye
protection. Carbide is a hard but brittle material. Foreign objects
in the work piece 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.
CAUTION: Do not cut ferrous metals (steel), masonry, glass,
masonry-type planking, cement board or tile with this saw.
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 on next page 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 reac-
tion 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
exist.
1. IMPROPER WORKPIECE SUPPORT
A. Sagging or improper lifting of the cut off piece can cause
pinching of the blade and lead to kickback (Fig. 10).
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.
