6.1 Preparatory actions
Operation 6.
6.1.1 Initial 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 blade arms of 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.) Fully open and close the tool once with the blade arms pointing upwards.
2.) Fully open and close the tool once with the blade arms facing downwards.
3.) Fully open and close the tool once with the blade arms pointing upwards.
4.) Fully open and close the tool once with the blade arms facing downwards.
6.1.2 Checking the pump unit
See separate operating instructions for the relevant unit
(or 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!
