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 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.
