4 - COMMANDS AND INSTRUMENTS

FRONT ANTI-TIP-OVER CONTROL
(only for models P38.12 – P38.13 – P38.14 – P40.17 – P38.13EE – P40.17EE – P60.10EE – P72.10EE)
The front anti-tip-over control device steps in when the machine is close to its
longitudinal stability limit, and locks all aggravating movements.
To restore the safe operating condition of the machine, the retraction manoeuvre
of the boom must be performed until the safety conditions are restored (indicator
light 54 on the instrument panel off and buzzer off)
If either it's not possible to retract the telescopic boom or this manoeuvre is not
sufficient to restore safe operating conditions for your machine, turn operating
mode selector (6) to the "C" position and hold it in that position. Then proceed
slowly and very cautiously with non-aggravating manoeuvres until safe operating
conditions are restored (both warning light 54 and audible alarm in the cab are
off)
WARNING! Before working with the machine, test the warning and
overload systems. With the boom just above the ground, pick up a load
and extend the boom to the point of overbalance. In the event of
malfunction do not use the machine until the fault has been repaired.
JOYSTICK (1)
(only for models P37.12PLUS – P38.12PLUS – P38.13PLUS – P38.14PLUS – P40.9PLUS – P40.17PLUS – P60.10 – P72.10
– P60.10EE – P72.10EE)
These machines are fitted with an electro-mechanical single-lever joystick for performing 5 hydraulic functions:
• Position A: lift telescopic boom
• Position B: lower telescopic boom
• Position C: rotate carriage downwards
• Position D: rotate carriage upwards
• Position E: extend telescopic boom
• Position F: retract telescopic boom
• Position G: release attachments installed on carriage
• Position H: • command for attachments installed on carriage
• Button L: shift machine to right
• Button M: shift machine to left
The movement speed required is proportional to the angle given to the joystick (the
larger the angle of the joystick the higher the movement speed), the rotation of the
control thumb-wheels (the larger the rotation of the thumb-wheels the higher the
movement speed) and diesel engine rpm (the higher the diesel engine rpm the higher the movement speed).
Depending on load conditions, it is possible to combine machine movements.
Movements stop automatically when the joystick, control thumb-wheel or button are released.
To enable the operation of the joystick it is necessary to press and keep pressed the red button (U) located on the rear.
To move the machine, press and hold down the dedicated button. The movement execution speed is set with a proportional
ramp and reaches maximum speed within about 4 seconds of pressing the control. To make small movements, press the
control switches briefly.
WARNING! Before operating the machine, please mark off the area where the machine needs to be operated, in
order to keep both people and vehicles away from it.
Should you need to operate the machine near overhead lines, the person in charge of safety shall require the
minimum safety distance from such lines to the manager of said lines, as well as from the authorities in charge of
safety and health in the workplace; in this way all necessary precautions shall be taken and potential accidents shall
be prevented.
For further information please refer to paragraph "INSTRUCTIONS FOR A CORRECT USE OF THE MACHINE NEAR
OVERHEAD LINES" in chapter "OPERATING INSTRUCTIONS".
