11.0 Repair and maintenance
11.10 Maintenance Performed by the User
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. We recommend performing maintenance after every 1.000 hours. 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.
