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 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 replacementparts.
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, sharpblade.
 
WARNING: Do not cut metal, masonry, glass, 
masonry-type planking, cement board, tile or plastic 
with thissaw.
Do not use abrasive wheels or blades. A dull blade will 
cause slow, inefficient cutting resulting in overload to the 
saw motor, excessive splintering and could increase the 
possibility of kickback. Please refer to the following table 
to determine the correct size replacement blade for your 
modelsaw.
