5. Depress the blade lock (K) while turning the saw spindle with the
blade wrench until the blade lock engages and the blade stops
rotating (Fig. 5).

NOTE: Never engage the blade lock while saw is running, or engage
in an effort to stop the tool. Never turn the saw on while the blade lock
is engaged. Serious damage to your saw will result.
TO REPLACE THE BLADE
1. To loosen the blade clamping
screw (H), depress the blade
lock (K) and turn the saw spin-
dle with the blade wrench until
the blade lock engages and the
blade stops rotating. With the
blade lock engaged, turn the
blade clamping screw clock-
wise with the blade wrench
(screw has left-hand threads
and must be turned clockwise
to loosen).
2. Remove the blade clamping screw (H) and outer clamp washer
(O) only. Remove old blade.
3. Clean any sawdust that may have accumulated in the guard or
clamp washer area and check the condition and operation of the
lower blade guard as previously outlined. Do not lubricate this area.
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.

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. 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 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 clean,
sharp blade.
CAUTION: Do not cut ferrous metals (steel), masonry, 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.
