4. Measure the distance between
the edge of the belt and the
straightedge at points A1 and A2
in figure. The difference between
measurements should be no
more than 1/16".
5. If the difference is greater or less
than 1/16" loosen the set screw
holding the motor drive pulley to
the shaft and adjust the pulley’s
position on the shaft until the A1
and A2 measurements are within
1/16" of each other.
6. Torque the motor drive pulley set
screw to 70-80 in.-lbs.
7. Visually inspect the motor drive
pulley to verify that it is perpen-
dicular to the drive motor shaft.
Points B1 and B2 of Figure
should appear to be equal. If
they are not, loosen the setscrew
of the motor drive pulley and
equalize B1 and B2, using care
not to disturb the belt alignment
performed in step 2.
8. Retighten the motor drive pulley
setscrew to 70-80 in.-lbs.
9. Reinstall belt guard.

Air Filter Inspection and
Replacement
Hot surfaces. Risk
of burn.
Compressor heads are exposed
when filter cover is removed.
Allow compressor to cool prior to
servicing.
A dirty air filter will not allow the com-
pressor to operate at full capacity.
Keep the air filter clean at all times.
1. Remove the air filter cover.
2. Remove the air filter from filter
cover.
IMPORTANT: Do not operate the
compressor with the air filter
removed.
3. Place new air filter into filter
cover. Refer to the “Repair Parts”
for the correct part number.
4. Replace air filter cover and lock
into place.
Motor Pulley/Flywheel
Alignment
NOTE: Once the motor pulley has
been moved from its factory set loca-
tion, the grooves of the flywheel and
pulley must be aligned to within 1/16"
to prevent excessive belt wear.
The air compressor flywheel and
motor pulley must be in-line (in the
same plane) within 1/16" to assure
belt retention within flywheel belt
grooves. To check alignment, per-
form the following steps:
1. Unplug air compressor from
power source.
2. Remove belt guard.
3. Place a straightedge against the
outside of the flywheel and the
motor drive pulley.
