Getting to Know Your Air Compressor
Belt Guard
Pilot/Unloader Vave
Air Filter
Safety Valve
Air Storage Tank
Tank Drain
Ball Valve
Oil Sight Glass
1. Belt Guard. The belt guard encloses the
pulleys and drive belt. It protects the
user from moving parts and directs
cooling air to the compressor pump.
2. Air Filter. The air filter keeps dirt and
debris from entering the compressor
pump and reduces compressor noise.
3. Oil Sight Glass. The oil sight glass
shows proper level and cleanliness of
the oil. Oil level should show ½ full
4. Tank Drain Valve. The tank drain valve
allows moisture to be removed from the
tank.
5. Pilot/Unloader Valve. The pilot/unloader
valve controls the engine rpm. When
loaded, the engine will run at maximum
operating speed and air will enter the
tank. When compressor reaches maximum
pressure, the engine will slow to an idle
and air will vent to atmosphere.
6. ASME Safety Valve. This valve auto-
matically releases air if the tank pressure
exceeds the preset maximum.
7. Ball Valve. The ball valve allows unregulated
outlet air with pressure up to 175 psi.
8. Air Storage Tank. The tank stores air for
later use.
9. Regulator and Gauge (Not Included).
Outlet air can be regulated by adjusting
the regulator knob. Clockwise will raise
outlet pressure and counterclockwise will
lower outlet pressure. Outlet pressure will
be displayed on gauge.
10. Tank Pressure Gauge. The tank pressure
gauge will display air pressure in tank.

Troubleshooting
!
WARNING
For your own safety do not try and
run the air compressor while troubleshooting.
TROUBLE REMEDYPROBABLE CAUSE
Low discharge pres-
sure
1. Listen for escaping air.
Ally soap solution to all
fittings and connections.
Bubbles will appear at
points of leakage. Tighten
or replace leaking fittings
or connections
2. Remove head and inspect
for valve breakage, weak
valves, scored valve plate,
etc. Replace defective
parts and reassemble
1. Air leaks
2. Leaking valves
!
CAUTION
Be sure that the old head
gasket is replaced with a
new one each time the
head is removed
3. Clean or replace air filter
element.
4. Replace and gaskets
proven faulty on inspection
5. Loosen engine mounting
bolts and move engine in
a direction away from the
compressor, being sure
that the engine pulley is
perfectly aligned with the
flywheel. Tighten engine
mounting bolts. Proper
belt tension should not
allow more than about ½
travel with less that 5
pounds of force
3. Restricted air intake
4. Blown gaskets
5. Slipping belts
