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, sharpblade.
 
WARNING: Do not cut ferrous metals(steel), masonry, 
glass, masonry-type planking, cement board or tile with 
thissaw.
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 ofkickback.
If you need assistance regarding blades, please contact your 
local service center listed on the back of themanual.
