7.3 OPENING THE CRANE
• Starting from the crane in rest position, operate the switch of „boom hoist up“ on remote control. When
the boom is roughly horizontal or in any case, higher than vehicle sides or other existing obstacles.
• Then operate the switch “crane swing”, to direct the boom in the desired direction.
• Then operate the switch “boom section extend” until the hook has reached the required position.
7.4 CLOSING THE CRANE
Closing the crane into rest position is performed by carrying out the opposite movements to those made to
open it, taking special care , at the end of the operation there are no parts protruding from the truck size.
Push the emergency button on the control board, disconnect the control board connection and save it in the
driver’s cab.
7.5 WINCH SYSTEM OPERATION
The Winch is mounted at the rear of the first section boom. It has capacities totally independent of the rest
of the crane and can normally pull more than the crane itself can withstand. Therefore, care must be taken
to insure that the load being lifted is within boom rating. To lift some of the heavier loads on the capacity
chart, it will be necessary to multiple-part reeve the winch block to increase the lifting capacity of the winch
(the speed is proportionately slower) and remain in the strength limitations of the winch and wire rope.
The winch load rating chart on each machine provides the information for pull limitations on the winch with
various applicable part reevings. These ratings are based on providing the proper operating safety factor on
the wire rope supplied with the machine. Therefore, any replacement rope must meet the rope specifica-
tions for size, construction and strength as outlined in specification sections of this manual.
7.6 BEFORE STARTING TRAVELING ON ROAD
Make sure that:
• The crane is in rest position as specified on chapter 7.4.
• The emergency button is turned off.
• The control board connection has been taken off the remote control and put in its box in the driver’s cab.
• The outriggers jacks are fully retracted, their stop pins are in their housing and secured with relevant
retainers.
• The manual boom sections, if installed, are secured with stop pins and safety retainers.
• The locking handle of the outrigger beams,
(2)
on pict. 15, is safely locked in place. Unexpected
sliding out of the outriggers beams when the truck is traveling could result in serious accidents.
• The lever of the shut-off valve on hydraulic jacks, see
(1)
in pict. 16, is in the CLOSED position.
• The PTO is disconnected.
• The overall dimensions of the crane in rest position are complying to regulations standard.
NOTE
Always remember that if the crane is left open on the body and it overcomes the
maximum height allowed by the law, it could hit bridges and other obstructions

MAIN ERRORS OCCURRING WHEN OPERATING THE CRANE
Because of lacking of care or of adequate instructions, some dangers may occur during crane operation.
Most common errors are:
• Slinging of loads exceeding the crane capacity: always check their actual weight not to overload the
crane or the winch. Special care has to be taken when handling big loads, when free they can remain
hanging on the crane and result in damages and accidents.
