Note regarding the modified release mechanism as of June 2004
When connecting the hoses, be aware of the following basic functions of the quick couplers:
Before coupling unlock the connect socket by turning the sleeve into position X. Retract sleeve
and connect plug and socket. Release sleeve and turn it into position Y.
Now the connection has been made and locked. Uncoupling is done in the reverse order.
Connection of the hoses is possible only, when they are depressurized.
In order to prevent contamination of the tool lines protect the couplings with delivered
dust caps.
Attention!
Quick couplers partly have special functions. Therefore it is not allowed screwing them
off from the hoses or to exchange them.
9 Operation
9.1 Preparatory measures
9.1.1 Initial start-up
Before initial start-up and after repairs, the device must be vented:
- Connect the device to the hydraulic pump (see item 8).
- Fully open and close the device at least twice without load (see item 9.2).
9.1.2 Inspection of operating state of the pump power pack
——> See separate Operating Instructions of the power pack (or manual pump) in question.
Note:
Before working on the motor pump or for coupling/decoupling the hoses, make sure
that the motor pump is switched off (electric connection) or disconnected from the
mains and that the lines are unpressurized.
9.2 Operating of the star grip 1
Opening of the blades:
Rotate star shape ring 1 to the right hand side and hold it in this position.
Closing of the blades:
Rotate star shape ring 1 to the left hand side and hold it in this position.
Load sustain function:
If released, the star shape ring 1 returns automatically to center position, maintaining
fully the load sustain function.
10 Cutting
10.1 Safety advise
Before the rescue operation begins, the object to be worked upon must be stabilized.
In each country, the country-specific safety regulations must be regarded.
When working in an environment which involves a risk of explosions, do not use motor/
engine powered pumps. Instead, use hand pumps.
