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 hub must be in-line
(in the same plane) within 1/16" (1.6 mm) to assure belt retention
within flywheel belt grooves. To correct misalignment, perform the
following steps:
1.
Set the Auto/Off lever to "OFF (O)", unplug the unit, and
relieve all air pressure from the air tank.
2.
Remove the outer belt guard.
3.
Loosen the motor mounting bolts.
4.
Loosen the set screws on the motor pulley.
5.
Align the motor pulley with the pump flywheel.
6.
Retighten the motor pulley set screws. Torque 145-180 in.-lbs
(16.4-20.3 Nm.).
7.
Adjust the proper belt tension.
8.
Retighten the motor mounting bolts. Torque to 20-25 ft.-lbs
(27.1–33.9 Nm)
9.
Reinstall the outer belt guard.
All moving parts must be guarded.
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.
Set the Auto/Off lever to "OFF (O)", 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 15-20 ft.-lbs (20.3-27.1 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.
