NOTE: Use 30W compressor oil or a
heavy duty SAE 30W, non-detergent,
SF grade or better oil DO NOT use
multi-weight automotive engine oils,
they will reduce compressor life. Under
extreme winter condition use SAE-10
weight oil.
5. Slowly fill crankcase to the top of
the fill hole. NOTE: Crankcase oil
capacity is approximately 16 fluid
ounces (0.5 L).
6. Replace oil fill plug (A) and tighten
securely.
AIR FILTER INSPECTION AND
REPLACEMENT
Risk of Burns.
Compressor head
and cylinder sleeve are very hot. Do
not touch. 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"
(1.6 mm) to prevent excessive belt
wear.
The air compressor flywheel and motor
pulley must be in-line (in the same
plane) within 1/16" (1.6 mm) to assure
belt retention within flywheel belt
grooves. To check alignment, perform
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.
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" (1.6 mm).
5. If the difference is greater or less
than 1/16" (1.6 mm) 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" (1.6 mm) 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.
