Following release, the star grip automatically returns to the
central position, guaranteeing the full load-holding.

6.1.1 Commissioning
Before commissioning and following repairs, the equipment must be deaerated.
- Connect the equipment to the hydraulic pump (see chapter “Connecting the
equipment”).
- Open / close the spreader arms of the equipment without any load at least twice (see
chapter “Operation of the star grip”).
6.1.2 Inspection of the pump unit
See separate operating instructions for the relevant unit (or for the hand pump).
REMARK:
Before each start-up of the hydraulic unit you have to make sure that the actuating
valves are set to depressurized circulation.
REMARK:
If you use mono-couplings, you can also couple when the hoses are pressurized!
