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.

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 work-
ing 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 out-
lined in Additional Safety Rules for Circular Saws. ff 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 inju_ always use eye pro-
tection. 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 dean,
sharp blade.
i_ CAUTION: Do not cut ferrous metals (steel), mason_ glass or tile
with this saw.
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.
