TROUBLE SHOOTING CHART
- Poor Vacuum Level.
- Vacuum Pump did not start
or quit running.
- Leak in service hoses or connections.
- Running free air for long period of time will
cause oil mist.
- Motor is jammed or locked.
- Low Temperatures.
- Low Temperatures.
- Excessive vacuum pump oil sucked into the
vacuum pump chamber.
- Check and tighten all connections.
- If running free air for long period of time, it may be necessary to
place the vacuum pump where the oil mist can dissipate. Check oil
levels periodically under this condition.
- With the power disconnected, remove fan gauge. See if the fan
will turn. If not, the pump mechanism may be jammed. This can
happen if the pump is dropped.
- It may be necessary to warm up the vacuum pump (oil) to free up
the vacuum pump mechanism.

-
Try restarting several times to clear out the excessive oil. This
condition can occur if the vacuum pump is shut down and left in
the vacuum. The vacuum in the chamber will cause the oil will
migrate and fill the chamber.
- Excessive Oil Mist.
- Vacuum pump tries to start.
Motor hum is heard, but then
stops.
- Vacuum pump “chugs as it
tries to start. The pump then
stops.
- Leak in service hoses or connections.
- Inlet Cap is loose or missing seal.
- Low Vacuum Pump Oil.
- Contaminated Vacuum Pump Oil.
- No power at power source.
- Power cord is not plugged in.
- Overload has tripped.
- Check and tighten all connections.
- Inspect inlet port caps.
- Check vacuum pump oil level, Add in needed.
- Check oil color, change if necessary.
- Check power source, breaker may have tripped.
- Ensure power cord is secure on both ends.
- If motor is hot, wait 10 minutes and restart. Check to see if the oil
level or oil contamination exists.
