Maintenance and Servicing
Under normal operating conditions the maintenance of the rotary vane pump is limited to:

external cleaning

checking running noises

checking the level and quality of the oil

regular oil changes
These maintenance intervals must be specified according to the prevailing operating conditions and
adhered to. The bearings of the drive motors are life-long lubricated and so maintenance-free.
CAUTION!
Only perform the work that is described here, and that which is permitted to be done
by the user. All other maintenance and service work may only be performed by the
manufacturer or a dealer authorized by him.
Beware of the pump parts being possibly contaminated by hazardous substances.
Wear protective clothing if there is contamination.
WARNING!
During repair or maintenance work which could endanger people because of moving or
electrically live components, the vacuum pump must be made safe by removing the
mains supply plug from the socket or by switching off the main contractor and
preventing it from being switched on again!
6.1 Oil Level Control
CAUTION!
Check the oil level regularly!
The oil consumption varies according to the vacuum pump
’s operating conditions. In order to keep the
vacuum pump at all times in an optimum operating condition, the oil level must be inspected at the oil
sight glass. The oil level must at all times be showing between the upper and lower markings on the oil
sight glass. The oil must be topped up if the oil level falls to the lower mark. We recommend to operate
pump with oil filling at upper marking FULL. This minimize the service needs and allows better dilution
of contaminants.
When additional oil is required, use only Directorr
™ Premium vacuum oil, pump performance is not
guaranteed with other brands of oil.
