Portable Air Compressors
Maintenance
(Continued)
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.
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.

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.
