WARNING
The vacuum pump is underfilled with oil.
Risk of fire!
• Insufficient oil quantity in the vacuum pump has the potential, under certain condi-
tions, to lead to self-ignition of the remaining oil in the vacuum pump.
WARNING
Degraded oil build up in oil lines.
Risk of fire!
• When changing the oil, it may be necessary to flush the vacuum pump to remove any
build-up of degraded oil from the sumps, oil lines, radiators, etc., to ensure proper oil
flow through the pump. Reduced oil flow, especially through radiators and cooling
coils, can cause mechanical damage or extreme overheating, which could cause the oil
vapors to ignite.
