2. Retract the lower blade guard (G) and place blade on saw spindle
against the inner clamp washer, making sure that the blade will
rotate in the proper direction (the direction of the rotation arrow on
the saw blade and the teeth must point in the same direction as
the direction of rotation arrow on the lower guard). Do not assume
that the printing on the blade will always be facing you when
properly installed. When retracting the lower blade guard to install
the blade, check the condition and operation of the lower blade
guard to assure that it is working properly. Make sure it moves
freely and does not touch the blade or any other part, in all angles
and depths of cut.
3. Place outer clamp washer (P) on saw spindle with the large fl at
surface against the blade and the side with ratchet teeth facing
out.
4. Thread the keyless blade clamp (H) into saw spindle by hand (clamp
has left-hand threads and must be turned counterclockwise to
tighten, as shown in Figure 4).
5. Depress the blade lock button (L) while turning the saw spindle by
hand until the blade lock engages and the blade stops rotating.
6. Extend the lever on the keyless blade clamp (H) and hand tighten
fi rmly (Fig. 4).
NOTICE: 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 (Fig. 3, 4):
1. Depress the blade lock button (L) and turn the saw spindle until
the blade lock engages and the blade stops rotating. With the
blade lock engaged, extend the lever on the keyless blade clamp
and turn clockwise (clamp has left-hand threads and must be
turned clockwise to loosen, as shown in Figure 4).
2. Remove the keyless blade clamp (H) and outer clamp washer (P)
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 (7-1/4" 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 Safety Instructions for All 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 qualifi ed
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.
