WARNING: This unit starts automatically.
ALWAYS shut off and unplug the compressor, and
bleed all pressure from the system before
servicing the compressor, and when the
compressor is not in use. Do not use the unit with
the shrouds or belt guard removed. Serious injury
could occur from contact with moving parts. Hot
surfaces. Risk of burn. Pump head, and
surrounding parts are very hot, do not touch (see
the Hot Surfaces identified in Fig. A). Allow
compressor to cool prior to servicing.
1. Move the Auto/Off switch to "OFF (O)", unplug the
unit, and relieve all air pressure from the air tank.
2. Remove the outer belt guard.
3. Mark motor position on saddle.
4. Loosen the motor mounting screws and slide the
motor toward the air compressor pump.
5. Remove the belt and replace
with a new one.
6. See the Adjusting Belt Tension before tightening
motor mounting screws.
To Adjust Belt Tension
1. Slide motor into original position, line the motor
up with the mark made earlier on saddle.
2. Tighten two outside motor mounting screws
enough to hold the motor in place for checking
pulley and flywheel alignment.
3. The belt should deflect 1/4" (6.5mm) at
midway between the pulley and the flywheel
when a 10 pound (4.5kg.) weight is applied at the
midway point.
4. When proper belt tension is achieved, tighten
motor mounting screws. Torque to 20-25 ft-lbs
(27.1-33.9 Nm)
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" (1.6mm) to prevent
excessive belt wear. Verify the alignment by performing the
following Motor Pulley/Flywheel - Alignment.
To Align Motor Pulley/Flywheel
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. Move the Auto/Off switch 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.
To Check Air Compressor Pump Intake
and Exhaust Valves
Once a year have a Trained Service Technician check the air
compressor pump intake and exhaust valves.
To Inspect Air Lines and Fittings for Leaks
1. Move the Auto/Off switch to "AUTO (-)" and allow
tank pressure to build. Motor will stop when tank
pressure reaches “cut-out” pressure.
2. Move 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.
