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 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 
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. 

  

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.
