TO ADJUST DRIVE BELT:
1. Remove belt guard.
2. Loosen the four fasteners holding
the motor to the baseplate.
3. Shift the motor in the proper
direction. The belt must be properly
aligned when adjustment is made.
4. Adjust flywheel or motor pulley so
that the belt runs straight.
5. If necessary, use a gear puller to
move the pulley on the motor shaft.
Tighten setscrew after pulley is
positioned.
6. Attach belt guard.

Troubleshooting Chart

Symptom
Low discharge pressure
Pump overheating causes
air filter to melt
Excessive noise
(knocking)
Operation
Check Oil Level
Drain Tank
Check Air Filter
Check Safety Valve
Clean Unit
Check Belt Tightness
Change Oil
STORAGE
1. When not in use, hose and
compressor should be stored in a
cool dry place.
2. Tanks should be drained of moisture.
and hose should be disconnected and
hung with open ends down to allow
any moisture to drain.
3. Protect the electrical cord from
possible damage by winding the
cord loosely around the handle of
the unit or coiling the cord up.
Possible Cause(s)
1. Air demand exceeds
pump capacity
2. Air leaks
3. Restricted air intake
4. Blown gaskets
5. Leaking or damaged
valves
1. Insulating gasket
between
filter and head is missing
2. Broken valves/blown
gasket
1. Loose motor or
compressor pulley
2. Lack of oil in crankcase
3. Worn connecting rod
4. Worn piston pin bores
5. Piston hitting the valve
plate

TECHNICAL INFORMATION

For information on the operation or
repair, please call 1-800-543-6400. In
Ohio or outside the continental U.S.,
call 513-367-4811.
Corrective Action
1. Reduce air demand or use a compressor with more
capacity.
2. Listen for escaping air. Apply soap solution to all fittings
and connections. Bubbles will appear at points of leakage.
Tighten or replace leaking fittings or connections.
3. Clean the air filter element.
4. Replace any gaskets proven faulty on inspection.
5. Remove head and inspect for valve breakage, misaligned
valves, damaged valve seats, etc. Replace defective parts
and reassemble.
Install a new head gasket each time the
CAUTION
!
head is removed
1. Install gasket.
2. Replace valves or install new gasket.
1. Loose motor or compressor pulleys are a very common
cause of compressors knocking. Tighten pulley clamp bolts
and set-screws.
2. Check for proper oil level; if low, check for possible
damage to bearings. Dirty oil can cause excessive wear.
3. Replace connecting rod. Maintain oil level and change oil
more frequently.
4. Remove piston assemblies from the compressor and inspect
for excess wear. Replace excessively worn piston pin or
pistons, as required. Maintain oil level and change oil more
frequently.
5. Remove the compressor head and valve plate and inspect
for carbon deposits or other foreign matter on top of
piston. Replace head and valve plate using new gasket. See
Lubrication section for recommended oil.
