Exhaust filter
Procedure
1. Apply a light coat of oil to the new o-rings.
2. Place the new o-rings on the front side of the exhaust filter.
3. Insert the exhaust filter into the operating fluid separator.
– The opening in the discharge area is facing upwards.
4. Assemble the exhaust connection with the 4 screws.
– Tightening torque:
6 Nm
During operation, the new exhaust filter becomes saturated with operating fluid. It is therefore normal for
the operating fluid fill level to drop slightly after the filters were changed.

● when the throughput decreases
● if there is visible contamination
Prerequisites
● Vacuum pump switched off
