OPERATION
This pump is self-priming. To prime it the first time, you must connect the air supply to the pump and slowly increase the air pressure from 0 to
the desired pressure using a pressure regulator. The pump starts to pump when an outlet valve is opened, for example an oil control gun.

TYPICAL INSTALLATION

Please see figure 4, a typical installation shown with all the recommended accesories for the pump to operate correctly.
NOTE: The compressed air supply must be between 30 and 170 psi (2 - 12 bar), and 80 to 100 psi is ideal.

TROUBLESHOOTING

SYMPTOMS
The pump is not working or there is
no oil delivery.
The pump begins to operate very
fast.
The pump keeps on operating
although the oil outlet is closed.
Oil leakage through the air outlet
muffler (35) or the leakage warning
hole on the pump body (52).
Air leakage through the air outlet
muffler (35).
Oil output too low or diminishes
over time.
REPAIR AND CLEANING PROCEDURE
WARNING: Before starting any kind of maintenance or repair,
!
disconnect the compressed air supply and open a downstream
valve to relieve the oil pressure.
During the assembly, ensure to apply grease to all the seals.
CLEAN THE MUFFLER
1. Unscrew and remove the plug (32).
2. Remove the muffler diffuser (33).
3. Replace the felt (34) with a new one.
4. Replace the diffuser (33) together with the new felt (34).
5. Replace the plug (32).

POSSIBLE REASONS
Not enough air supply pressure.
Some outlet line component is clogged or closed.
The tank is empty or the oil level is beneath the
suction tube inlet.
There is an oil leakage in some point of the outlet
circuit.
Oil has by-passed to the air motor caused by worn or
damaged seal (48).
Damaged or worn piston O ring (27).
The air seal (8) of the inverter assembly is damaged
or worn.
Damaged or worn spool seals.
Contamination in the foot valve.
Contamination in the upper valve.
The exhaust felt (34) is clogged by compressed air
dirt or lubricant.
