PROBLEM POSSIBLE CAUSE
Low discharge 1. Air demand exceeds pump
pressure.
2. Restricted air intake.
3. Air leaks (fittings, tubing on
4. Blown gaskets.
5. Leaking or damaged valves.
Excessive noise 1. Loose motor pulley or
(knocking).
2. Loose fasteners on pump or
3. Lack of oil in crankcase.
4. Worn connecting rod.
5. Worn piston pin bores.
6. Piston hitting the valve plate.

CORRECTIVE ACTION

1. Reduce air demand or use a compressor with more capacity.
2. Clean or replace the air filter element.
3. 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. Use pipe
thread sealant.
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.
CAUTION
Unit Care and Maintenance. Install a new head
gasket each time the head is removed.
1. Tighten pulley / flywheel clamp bolts and set-screws.
2. Tighten fasteners.
3. Check for proper oil level; if low, check for possible damage
to bearings. Dirty oil can cause excessive wear.
4. Replace connecting rod. Maintain oil level and change oil
more frequently.
5. 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.
6. 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.
7. Replace check valve.
DANGER
Risk of Explosion. Do not
disassemble check valve with air
pressure in tank.
Replace the unloader valve if it does not release the pressure
for a short period of time when the unit shuts off.
