To ensure efficient operation and longer life of
the air compressor unit, a routine maintenance
schedule should be prepared and followed.
The following routine maintenance schedule is
geared to a unit in a normal working environ-
ment operating on a daily basis. If necessary, the
schedule should be modified to suit the condi-
tions under which your compressor is used. The
modifications will depend upon the hours of op-
eration and the working environment.
Compressor units in an extremely dirty and/or
hostile environment will require a greater fre-
quency of all maintenance checks.
ROUTINE MAINTENANCE SCHEDULE
1. Drain water from the air tank, any moisture
separators or transformers.
2. Check for any unusual noise and/or vibration.
3. Manually check all safety valves to make sure
they are operating properly.
4. Inspect air filter, replace if necessary.
5. Inspect air lines and fittings for leaks; correct
as necessary .
• Check condition of air compressor pump in-
take and exhaust valves.
• Check condition of check valve. Replace if
damaged or worn out.
FILLING WITH OIL
1. Remove the oil filler plug.
2. Slowly pour the proper oil into the pump
crankcase.
3.Always keep oil level in the middle of the sight
glass.
CHANGING THE OIL
NOTE: Every 300 hours or 3 months, whichever
comes first.
1. Remove the oil drain plug. Allow oil to drain
completely.
2. Replace the oil drain plug (The use of a sea-
ling compound or Teflon tape to avoid leakage
is recommended.)
3. Refill with the recommended oil to the proper
level. (AII wenling cyclone dealer available).

SERVICE INSTRUCTIONS
Air Filter - Inspection and Replacement:
• Keep the air filter clean at all times. Do not ope-
rate the compressor with the air filter removed.
• A dirty air filter will not allow the compressor
to operate at full capacity. Before you use the
compressor , check the air filter to be sure it is
clean.
• If it is dirty, check and replace the filter element.
WARNING: SAFETY VALVE - INSPECTION IF
THE SAFETY VALVE DOES NOT WORK PROPERLY,
OVERPRESSURIZATION MAY OCCUR, CAUSING
AIR TANK RUPTURE OR AN EXPLOSION. OC-
CASIONALLY PULL THE RING ON THE SAFETY
VALVE TO MAKE SURE THAT THE SAFETY VALVE
OPERATES FREELY. IF THE VALVE IS STUCK OR
DOES NOT OPERATE SMOOTHLY, IT MUST BE R
PLACED WITH THE SAME TYPE OF VALVE.
1. Release all air pressure from air tank and un-
plug outfit.
2. Remove shroud.
3. Loosen the top and bottom nut of the outlet
tube and remove.
4. Remove the pressure release tube and fitting .
5. Unscrew the check valve (turn countercloc-
kwise ) using a socket wrench.
6. Check that the valve disc moves freely inside
the check valve and that the spring holds
the disc in the upper , closed position. The check
valve may be cleaned with a suitable solvent.
7. Apply sealant to the check valve threads . Re-
install the check valve (turn clockwise).
8. Replace the pressure release tube and fitting.
9. Replace the outlet tube and tighten top and
bottom nuts.
10. Replace the shroud.
MOTOR
The motor has a manual reset thermal overload
protector switch. If the motor overheats for
any reason, the overload protector will shut off
the motor. The motor must be allowed to cool
down before resetting the overload switch and
restarting.
If the overload protector shuts the motor off
frequently, check for a possible voltage pro-
blem. Low voltage can also be suspected when:
1. The motor does not get up to full power or
speed.
2. Fuses blow out when starting the motor;
lights dim and remain dim when motor is star-
ted and is running.
