9.5 Hydraulic connection of the standard machine with 5-line hydraulic system to the prime mover
To connect the hoses, proceed as follows:
1- release the pressure inside the system (see p.m. manual);
2- connect the three motor hoses (ref. “1” fig. 5) using the quick coupling fittings (see below); it is essential to
insert the drain line first.
3- connect the two side shift hoses (ref. “2” fig. 5) connect the hoses using the quick coupling fittings (see
following section);
4 - check for any oil leaks:
a) get on the prime mover and start the engine;
b) activate the high flow auxiliary equipment control to power up the hydraulic motor;
b) on the prime mover, activate the standard auxiliary equipment control to operate the side shift jack;
d) switch off the engine, remove the ignition keys, and get off the prime mover; now check for signs of
leaks near the hose fittings.
Fig. 5
The figure shows an example of how to connect the hoses to the prime mover.
The machine is connected to the prime mover via hydraulic hoses; make sure the hoses are
not tangled together, as this could prove hazardous, and are not likely to be crushed or
exposed to tension during work manoeuvres.
Residual risk of burns: the hydraulic oil, hoses and fittings can all reach extremely high
temperatures whether the machine is fitted or not. Use appropriate personal protection
equipment.
The operation must be carried out by one person (operator) only.

N.B. When connecting the hoses to the prime mover, the drain line must be connected first.

If you use threaded quick couplings, make sure they are tightened fully and correctly. Where
possible, we recommend you use flat-faced quick couplings with a safety ring nut.
