Filling the lubricant
The oil chambers of the roots pump are each equipped with a fill level limiter. A riser tube
limits the max. fill level.
● Filling quantity, motor side: approx. 1.60 l
● Filling quantity, opposite side: approx. 1.40 l
Filling with lubricant
1. Make sure that there is sufficient space underneath the pump to be able to place a collection re-
ceptacle for the lubricant.
2. Unscrew the filler screws.
3. Hold the fill level limiter with the ring spanner and unscrew the drain screw at the same time.
4. Place a collection receptacle under each drain.
5. Fill the lubricant on both sides up to the maximum fill level.
– Once full, lubricant overfills the fill level limiter, and drips out of the drain hole.
6. Screw the filler and drain screws back in.

WARNING
Risk of crushing from rotating parts
Fingers and hands may be caught by rotating pistons within the connection flange. This results in se-
vere injuries.
