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 (0)", unplug the unit, and
relieve all air pressure from the 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).
7.
Adjust the proper belt tension.
8.
Retighten the motor mounting bolts.
Torque to 15-20 ft.-lbs (20.3-27.1 Nm).
9.
Reinstall the outer belt guard. All moving parts must be
guarded.
PUMP INTAKE AND EXHAUST VALVES
Once a year have a Trained Service Technician check the pump
intake and exhaust valves.
INSPECT AIR LINES AND FITTINGS FOR LEAKS
1.
Turn the Auto/Off switch to "Auto (1)" and allow tank pres-
sure to build. Motor will stop when tank pressure reaches
"cut-out" pressure.
2.
Set the Auto/Off switch to "Off (0)" and unplug unit.
3.
Apply a soap solution to all air-line fittings and connections/
piping to find leaks.
4.
Pull ring on safety valve allowing air to bleed from the tank
until tank pressure is approximately 20 PSI. Re-
lease safety valve ring.
5.
Drain water from tank by opening drain
valve (I).
6.
Correct any leaks found.
NOTICE: Even minor leaks can cause the air compressor to
overwork, resulting in premature breakdown or inadequate
performance.
PUMP HEAD BOLTS - TORQUE
The pump head bolts should be kept properly torqued. Check
torque of the head bolts after the first five hours of operation.
Torque to 15-20 ft.-lbs. (20.3-27.1 Nm).
