6.2 Operating the star grip
Opening the device ( ):
Turn the star grip in the direction of the relevant symbol and keep
in this position.
Closing the device ( ):
Turn the star grip in the direction of the relevant symbol and keep
in this position.
“Dead-man’s” function:
Following release, the star grip automatically returns to the
central position, guaranteeing full load-holding.
REMARK:
We recommend that during deaeration, the attached aggregate for the hydraulic
supply should stand on a higher level than the body of the rescue tool.
Recommended procedure for deaeration of the rescue tool:
1.)
open and close fully with the spreader arms facing
upwards
.
2.)
open and close fully with the spreader arms facing
downwards
.
3.)
open and close fully with the spreader arms facing

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.
Before coupling the quick-disconnect couplings, the actuating valves of the
hydraulic unit are set to depressurized circulation.
If you use mono-couplings, you can also couple when the hoses are pressurized!
