Performing maintenance
To install the hose coupling, proceed as follows:
1. Push the hose coupling (27.2) onto its matching part on the unit (27.1)
and turn the coupling (27.2) by ≈ 90 ° clockwise.
2. Manually tighten the collet (27.3) on the hose coupling (27.2) clockwise.
If the collet is not tightened or not sufficiently, the pump will
take in air via the hose coupling.
3. Start up the unit.
4. Check the unit for leaks while it is operating.
