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, sharp
blade.
WARNING: 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.
If you need assistance regarding blades, please call
contact your local service center listed on the back
of the manual.
