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 115-125 in.-lbs
(13.0 - 14.1 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. 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 15-20 ft.-lbs. (20.3-27.1 Nm).
