If using flat-faced quick couplings,
proceed as follows (ref. in fig. 6):
A-
Fit the male section (ref. “7”) into the female section (ref. “8”) until you hear it click into place in the ring nut
(ref. “9”);
B-
Turn the ring nut (ref “9”) so that the notch (ref “10”) is not aligned with the spherule (ref. “11”), thereby
preventing accidental disconnection.
Fig. 6
The figure shows flat-faced quick couplings with a snap-
fastening safety ring nut.
Before connecting up, carefully clean all the quick
couplings on the machine and the prime mover.
If, for some reason, there is residual pressure in the
prime mover’s hydraulic system, you will not be able
to fit the male section of the coupling into the female
section. Follow the instructions given by the prime
mover’s manufacturer to relieve the pressure.
9.6
Hydraulic disconnection of the standard machine with 3- or 5-line hydraulic system from the
prime mover
Before leaving the operator’s seat on the prime mover, make sure the machine is resting on
flat ground, the prime mover is stabilised and the key has been removed from the ignition.
Residual risk of burns: the hydraulic oil and hoses can reach extremely high temperatures
whether the machine is fitted or not. Use appropriate personal protection equipment.
IMPORTANT:
Always disconnect the drain line last of all.
To disconnect the hosing, proceed as follows:
1- stop the motor;
2- release the pressure in the system;
3- get off the machine and disconnect the quick coupling fittings (see specific section below);
4-
FOR THE 3-FITTING VERSION ONLY:
disconnect the power cable (ref. “2” para. 9.4).
If using flat-faced quick couplings,
proceed as follows (for the references used, see fig. 6, para. 9.5):
- Turn the ring nut (ref “9”) so that the notch (ref “10”) is aligned with the spherule (ref. “11”), and then push it
towards the ball to disengage the joint.
