Fig. 10: Filling with lubricant
1 Filler screws 3 Fill level limiter
2 Drain screw
For safe filling of the lubricant, the pump has one fill level limiter in each of the two oil
chambers that determines the max. fill level via a riser tube. Both sight glasses serve only
for loss checks.
● Filling quantity, motor side: approx. 1.7 l
● Filling quantity, opposite side: approx. 1.5 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.
