Functional Tests
34

Press the movement enable pedal and act
on the joysticks: the functions must be
operative.
Auxiliary pump test

Press the red emergency stop button:
reset it to stop the system.
 Activate the emergency pump and test the
movements of the booms and platform.
NOTE: to avoid consuming the batteries,
limit the test duration time.
 After confirming the correct working,
deactivate the auxiliary pump and restart
the system.
Testing the steering methods
 Operate on the selector concerned and
check the working of the three types of
steering of the wheels.
Testing the warning sound
 Push up the switch of the warning sound
and check its working.
Testing the selection of the
movement speed
It is possible to select mainly 2 speeds from
the control panel on the platform:

high movement speed (represented by
the hare) of 5 km/h that can only be
activated with the primary telescopic
boom completely lowered and retracted;
 low movement speed (represented by the
tortoise) of 1 km/h, that can be activated
with the boom in the operating position.
 The third option makes it possible to
overcome small obstacles keeping the
transfer speed minimum but with the
motor rpm maximum to impress all the
power on the drive wheels
The high/low movement speed can be
selected not only by the selector mentioned
but also electronically by means of software
installed on the truck: as soon as the primary
telescopic boom moves from the completely
lowered, retracted position, the electronic
control automatically activates low speed to
protect the operators on board.
At the end of the electronic control tests,
proceed as described below.
Select the maximum movement speed; with
the primary telescopic boom lowered and
retracted slowly activate the movement: the
truck moves at a speed of 1.4 m/s (5 km/h).

With the primary telescopic boom in the
completely lowered and retracted position,
lift it by 10° and slowly activate the
movement: the truck must not exceed a
speed of 30 cm/s (1 km/h).

Restore the boom to the completely
lowered hold position.
 With the primary telescopic boom in the
completely lowered and retracted position,
extend it by 1.00 m and slowly activate the
movement: the truck must not exceed a
speed of 30 cm/s (1 km/h).
 Restore the boom to the completely
lowered hold position.

If the movement speed with the primary
telescopic boom raised and extended
exceeds 30 cm/sec (1 km/h), stop the
truck immediately and call an authorised
service centre.
Testing the movement and braking
 Press the pedal switch down.
 Slowly move the movement control knob
in the direction indicated by the black
arrow on the control panel until the
machine starts moving, then restore the
knob to the central position.

Result: the machine must move in the
direction shown by the black arrow on the
