English within 1/16" (1.6 mm) to prevent excessive belt wear. Verify the alignment by performing the following Motor Pulley/Flywheel Alignment. 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" (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. Set the Auto/Off lever to "Off", unplug the unit, and relieve all air pressure from the air tank. 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 measure- ments should be no more than 1/16" (1.6 mm). 5. If the difference is greater 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. Tighten the motor drive pulley set screw. 7. Visually inspect the motor drive pulley to verify that it is per- pendicular 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. Torque to 145-165 in lbs (16.4-20.3 Nm). 9. Reinstall belt guard. Air Compressor Pump Intake and Exhaust Valves Once a year have a Trained Service Technician check the air compressor pump intake and exhaust valves. Inspect Air Lines and Fittings for Leaks 1. Set the Auto/Off lever to "Off", unplug the unit, and relieve all air pressure from the air tank. 2. Apply a soap solution to all air line fittings and connections/ piping. 3. Correct any leaks found. IMPORTANT: Even minor leaks can cause the air compressor to overwork, resulting in premature breakdown or inadequate performance. Air compressor Head Bolts - Torquing The air compressor pump head bolts should be kept properly torqued. Check the torques of the head bolts after the first five hours of operation. Torque to 8-11 ft.‑lbs. (11-15 Nm). Service and Adjustments ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED MUST BE PERFORMED BY TRAINED SERVICE TECHNICIAN. Risk of unsafe operation.

Motor Pulley/Flywheel -
Alignment.
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” (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.
Set the Auto/Off lever to “Off”, unplug the unit, and relieve all
air pressure from the air tank.
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
measure-
ments should be no more than 1/16” (1.6 mm).
5.
If the difference is greater 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.
Tighten the motor drive pulley set screw.
7.
Visually inspect the motor drive pulley to verify that it is per-
pendicular 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. Torque to 145–165 in lbs
(16.4–20.3 Nm).
9.
Reinstall belt guard.
Air Compressor Pump Intake and
Exhaust Valves
Once a year have a Trained Service Technician check the air com-
pressor pump intake and exhaust valves.
Inspect Air Lines and Fittings for Leaks
