4. Measure the distance
between the edge of the
belt and the straight-
edge at points A1 and
A2. The difference
between measurements
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 measure-
ments are within 1/16" (1.6 mm) of each other.
6. Tighten the motor drive pulley set screw. Torque to
145-160 in-lbs. (16.4-18.1 Nm).
7. Visually inspect the motor drive pulley to verify that it is per-
pendicular to the drive motor shaft. Points B1 and B2 should
appear to be equal. If they are not, loosen the set screw of the
motor drive pulley and equalize B1 and B2, using care not to
disturb the belt alignment.
8. Retighten the motor drive pulley set screw.
Torque to 145-160 in.-lbs. (16.4- 18.1 Nm).
9. Reinstall outer 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
1. Turn the Auto/Off switch to “Auto (1)” and allow tank pressure
to build. Motor will stop when tank pressure reaches “cut-out”
pressure.
2. Set the Auto/Off switch to “Off (O)” and unplug unit.
3. Apply a soap solution to all air-line fittings and connections/
piping to look for any leaks.
4. Pull ring on safety valve allowing air to bleed from the tank
until tank pressure is approximately 20 PSI. Release safety
valve ring.
5. Drain water from air tank by opening drain valve on bottom
of tank.
6. 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 20-24ft.-lbs. (28-32 Nm).
Service and Adjustments
ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED
MUST BE PERFORMED BY TRAINED SERVICE TECHNICIAN.
Risk of unsafe operation. Unit cycles automati-
cally when power is on. When servicing, you may be exposed
to voltage sources, compressed air, or moving parts. Before
servicing unit unplug or disconnect electrical supply to the air
compressor, bleed tank of pressure, and allow the air compres-
sor to cool.
