• Check every month the state and correct functioning of all the parts subject to wear: pins, valves, hoses,
sliding pads and bushings, etc. If necessary replace with genuine spare parts.
• It is absolutely forbidden to alterate the hydraulic circuit and open the safety seals. Failure to comply will
cause automatically the voiding of any warranty on the product. Valves adjustments or setting must be
done only by authorized installer workshops.
• Overheating of hydraulic oil may burn the sealing parts and alterate the oil itself. This can be caused by
an excessive oil flow of the pump or by repeated stroke ends of the cylinders.
• Check that the pump supplies the control valve with the oil flow suggested in our technical specifica
tions.
7.2 STABILIZING THE TRUCK
• Bearing in mind the job to be done, the vehicle has to be positioned in the most convenient position,
stopped with the parking brake and the tires blocked.
• The hydraulic circuit of the crane shall be activated as follows:
Cranes driven by DC power pack
The DC power pack is connected with the truck battery. The electric pump will start every time a switch of
the remote control is moved. The crane can work even when the engine of the truck is off, but it is strongly
recommended of keeping the engine idling, so the alternator can continuously charge the battery of the
vehicle.
A battery switch (as shown in pict. 21), fully dedicated to the crane electrical system, must be present.
This battery switch must be turned on (or off) every time the crane starts (or terminates) the working
session.
DANGER
DC electric motor overheating. Keep the electric pump running for short periods to avoid its
over heating. The maximum working period of the pump depends on the pressure requested
by the maneuvers, but should never exceed 5÷6 minutes in any case, with intervals of 20 min.
to enable a sufficient cooling.
• Extend the outriggers beam. Its release is made turning 180° upwards the locking handle (2) on picture 11.
Pull the beam (1) on picture 11 out for a length of approx. 20 cm (8 in.), then turn again the locking handle
180° downwards in its previous position. Pull again out the outrigger beam, and the locking pin of the handle
will automatically engage and lock the beam when its working position is reached. Always extend fully the
outrigger beam to its working position (i.e.: maximum opening position) to grant the maximum stability of the
vehicle and safety. Always pull and push the outrigger beam acting on the handle (3) on picture 11 foreseen
for this purpose.
ATTENTION
The outrigger beam is in its working position when the yellow band existing on the beam can be
entirely seen.
