Problem
The index on vacuum gauge
can’t reach the green area.
The vacuum gauge index reaches
the green area, but oil isn't
evacuated.
The vacuum gauge shows
leakage and can’t suction
the oil.
Cause
1. Air supply pressure is too low.
2. Air flow is not enough.
1. Oil temperature is too low.
2. The suction hose, valve or
fitting is jammed.
1.O-ring of the suction fitting is
broken.
2. The bottom of the suction hose
is higher than the oil level.
Solution
1. Increase the air supply pressure.
2. Enlarge the air inlet diameter,
shorten the hose length.
1. Increase the oil temperature
2. Clean or replace suction hose, valve
or fitting.
1. Change the O-ring.
2. Keep the suction hose straight
and ensure the hose is immersed in
the oil.
TROUBLE SHOOTING GUIDE
CAUTION
• Never fill the reservoir over the maximum level indicated by the gauge that is located on the side
of the reservoir.
• Don’t exceed maximum pressure 0.5bar/7.5psi for draining.
• Air pressure for vacuum is maximum 8bar/115psi.
• Open the bottom nut of the reservoir periodically and clean out any dirt.
