7. Operation
7.1 Preparatory measures
7.1.1 Commissioning
Before commissioning and following repairs, the equipment must be deaerated.
- Connect the equipment to the hydraulic pump (see chapter “Connecting the
equipment”).
- Extend / retract the equipment without any load at least twice (see chapter “Operation
of the star grip”).
REMARK:
We recommend that during the deaeration, the attached aggregate for the
hydraulic supply should stand on a higher level than the body of the rescue
tool.
Recommended procedure for the deaeration of the rescue tool:
1.) open and close fully with the piston rod facing upwards.
2.) open and close fully with the piston rod facing downwards.
3.) open and close fully with the piston rod facing upwards.
4.) open and close fully with the piston rod facing downwards.
7.1.2 Inspection of the pump unit
See separate operating instructions for the relevant pump 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:
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!
