8 Connection of the tool
8.1 Hydraulic
Two short hoses (each 0.5 m long) are fitted to the tool; they are connected with the motor pump
via a hose pair (5 m / 10 m / 20 m, as is necessary). All hoses are colour marked and have quick-
connect couplings so that they can be connected without the risk of mix-up:
HP = High pressure ——> red R = reflux ——> blue
8.2 Connection of the plug-in coupling counterparts for HP and R hoses
The device is connected to the hydraulic pump with the plug-in coupling counterparts (plug and
socket), there being no risk of mix-up.
Before coupling, remove the dust protection covers and unlock the connect socket with adjusting
ring by turning it. Withdraw the sleeve and connect plug and socket while holding the sleeve in this
position. Release the sleeve and set the showglass to „red“ with the adjusting ring. Now the parts
are connected and locked. Decoupling is done in the reverse order.
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.
