AUTOMATIC HOSE REWIND

1) Put the gearbox lever in the working posi-
tion ( fig.21 pos. 1).
2) Increase the machine pressure slowly until
it reaches the operating pressure.
3) Select the gear with the lever of the gear-
box (fig.21 pos. 2)
Final speed is set by the computer ( fid. 22)
MOD. G4
from 32.8 – 49.2 ft/hr
from 49.2 – 98.4 ft/hr
from 98.4 – 196.8 ft/hr
196.8 ft/hr
CAUTION: whenever the pumping system stops supplying water, the machine will stop and automatically starts working
again when the pressure is restored.

2.3 AUTOMATIC MACHINE STOP

When the hose is completely wound, the hose stopping hook pushes against the
lever (fig.23), and puts the gearbox automatically in the idle position 0, thus
stopping the hose winding. At the same time the water discharge valve and the
shut-off valve are operated for the automatic stopping in the pumping stations (if
the machine is equipped with one of these valves).
2.4 INSPECTIONS TO BE CARRIED OUT DURING START UP OPERATION
1) Check that the hose-guide fork is in the correct
position (lined up with the hose or slightly press-
ing it towards the already wound up loop). This
inspection must be carried out with the hose
completely laid out. To adjust the position of the
hose-guide fork:
- take the protection guard of the reel side chain
off (fig.24 a)
- open the connecting link of the chain,
- then rotate the hose-guide scroll bar to the right
or to the left until the hose-guide fork is in the
correct position (fig.24 b).
For safety reasons this operation must
carried out when the machine is not operative.
2) Check that the automatic disengaging sys-
tem at the end of the stroke is adjusted. Push-
ing manually on the automatic disengaging
(fig.25a) bar and check that the gearbox is
neutral. If the gearbox stopping lever is not
properly adjusted, adjust it through the screw
(fig.25 b).

CAUTION: when changing gear make sure to decrease
the speed of the turbine using the appropriate lever or by
the computer, if any.
WARNING:. These instructions must be strictly respected
particularly when shifting from the third to the fourth
speed (gear).
