Oil
Checking
1. Remove the oil fill plug
(A). The oil level should be
even with the top of the
fill hole and no lower than
6 threads from the top of
fill hole.
2. If needed, slowly add oil
until it reaches the top of
fill hole.
NOTE: Use a air compressor
oil such as Sears 9-16426 or SAE-20 (API CG/CD
heavy duty motor oil. Under extreme winter conditions
use SAE-10 weight oil.
Changing
1. Remove the oil fill plug (A).
2. Remove the oil drain plug (B) and drain oil into a
suitable container.
3. Replace the oil drain plug (B) and tighten securely
NOTE: Use a air compressor oil such as Sears 9-
16426 or SAE-20 (API CG/CD heavy duty motor oil.
Under extreme winter conditions use SAE-10 weight
oil.
4. Slowly fill crankcase to the top of the fill hole.
Crankcase capacity is 16 fluid ounces (473.2 ml).

5. Replace oil fill plug (A) and tighten securely.

Air Filter - Inspection and Replacement

are exposed when filter cover is removed.
Allow compressor to cool prior to servicing.
A dirty air filter will not allow the compressor to oper-
ate 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 location, 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, 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".
5. If the difference is greater or less than 1/16"
loosen the set screw holding the motor drive pul-
ley 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. Tighten the motor drive pulley set screw to 70-80
in.-lbs.
7. Visually inspect the motor drive pulley to verify
that it is perpendicular 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.
