Pump oil ages. Carry out an oil change, if one of the following
points applies:
the pump oil is of darker color compared to new oil,
the pump oil is considerably discolored compared to new oil,

there are particles in the oil.
The oil change interval depends on of the individual application:
Check oil level every time before starting the pump.
Under normal operating conditions we recommend a yearly oil
change.
Especially if corrosive gases or vapors have been pumped, it may
be appropriate to check the oil frequently and according to the
users' experience and to carry out an oil change, if necessary.
Oil change procedure
>
We recommend a temperature of the vacuum pump in the
range from 12 to 40 °C (54 to 104 °F) for the oil change pro
‑
cedure. The viscosity of a cold pump's oil is increased making
the oil change more difficult.

1. Switch off the pump and unplug
the power plug from the

ly if parts of the pump are disassembled.
2.
2.
Disconnect the vacuum pump from the apparatus.
