3 Maintenance (see chapter 1.1)
The vacuum pump must be switched off and secured against accidental
switch-on for all maintenance jobs. All work must be done by suitably trained
personnel.
The following maintenance-schedule shows the regular maintenance periods
for an average use of the pump.
Unfavourable ambient conditions and/or aggressive media may
significantly reduce the maintenance intervals.
On the other hand, favorable conditions may allow longer operating
periods or to skip the first oil change.
Maintenance job Frequency Section

To simplify the maintenance work we recommend combining several jobs.
3.1 Oil level
The oil level shall be checked at least once a day and must be, while the pump is
in operation, close to the MAX mark. Should the oil level be below the MIN mark
switch off the pump, check it (see chapter 4) and add the required amount of
oil.
3.2 Oil change
Oil changes, depending on operating conditions (products, vapours, ambient
temperature…) must be done every 500 to 2000 operating hours or at least
every 6 months.
If there is considerable pollution, it could be necessary to change the oil more
frequently. Special oils allow to extend the oil changing period.
Oil changing must be done with a switched off
and still warm pump. Open the oil drain plug and let run out the used oil into an
appropriate container. Refasten the oil drain plug when oil runs slower, start up
the pump briefly (5 sec. max) and switch off immediately. Re-open the oil drain
plug and drain the rest of the oil.
