Adjustment Of The Speed Equalizer; Use Of The Compressor (Optional); Rapid Hose Retraction - IRTEC MUSTANG Manuel D'instructions Pour L'utilisation Et L'entretien

ATTENTION: when the machine is put in the idle position with the hose laid down,
the reel makes a violent half turn backwards. Before carrying out this operation
make sure that nobody is near the reel.
3) If the machine is fitted also with shut-off or discharge valve, check that both the auto-
matic disengaging system at the end of the stroke and the 3-way valve which controls the
opening and the shutting of the valves is activated. If necessary, adjust the stroke of the
valve drive rod (fig.26).
4) Adjust the chain tension by the chain tightener
(fig.27).
5) If the machine is equipped with computer check
that sensor is mounted as in picture 25c.
N.B. If the machine is equipped with computer,
Rain Control check that at the end of the operation the limit switch is activated.

2.5 ADJUSTMENT OF THE SPEED EQUALIZER

The regulation is automatic done by the computer
If the machine is equipped with a computer the by-pass adjusting is automatic. For
computer use see the use and maintenance manual.

2.7 USE OF THE COMPRESSOR (OPTIONAL)

Open the valve placed on the compressor-connecting pipe (fig.28); open the breather
placed on the end cap (fig.29) and close the second water inlet with the end cap. Take
off the end cap under the rain gun trolley (fig.30); operate the tractor P.T.O. setting
the speed rate immediately at 540 rpm; close the breather placed over the connecting
pipe to let the air flow completely into the machine (fig.29. When the machine is
empty (3-4 minutes) open the breather and stop the P.T.O. When the drainage is com-
pleted the ball valve at the delivery side of the compressor (fig.28) must be closed.
Damage to the compressor can be caused if the valve is not closed
As the water may flow in during operation.
CAUTION: when the machine has been drained through the compressor, a
residual pressure of 2-3 bar remains inside the hose so it is dangerous to take off
the end cap without having opened the breather fig.29.
Check the lubrification of the compressor during the draining, the oil must pour
through the valve placed over the compressor (visible through the transparent
glass bowl). If necessary, regulate the flow using the adjusting screw (fig.31).

2.8 RAPID HOSE RETRACTION

The function of the P.T.O. power takeoff on the gearbox is to rewind the hose
quickly by the tractor. In case of inconvenience such as rainfall etc., to rewind the
hose by the P.T.O. proceed as follows:
1) Make sure that the gearbox lever no.2 is in "hose-rewind" position to prevent the
P.T.O. from running loose.
2) Connect the P.T.O. shaft from the tractor to the gearbox power takeoff.
3) Activate the power takeoff and wind up the hose.
