3.1.4 Connecting and disconnecting the cut-
ter
Connecting and disconnecting the
cutter in pressure-free state!
Completely switch off the power pack at the
master switch and press switches T1 and T2
(23) simultaneously approx. 3 - 4 times. This
actuates the directional control valves and
depressurises the pressurised hydraulic return
hose (72) (see hydraulic and pneumatic circuit
diagram).
Then switch off the compressed air supply.
The two hydraulic hoses (70 + 72) and the con-
trol hose unit (76-83) can now be unscrewed.
The hydraulic couplers are self-locking so that no oil
escapes when they are disconnected.
Protect the coupling and plug parts
against soiling!
