3.11. SPECIAL FUNCTION BUTTON FN
On the main desk there is a button with name FN (Part 9 Fig. 3.1), with this switch
you can:
1) lifting and lowering the boom when the machine is on the tracks
2) move the stabilizers without pins
Function 1
In case of a particularly important slope or truck loading ramps, the boom can be lifted
of the needed angle to avoid the cage touching the ground, even without give pressure
to the stabilizers, with the extensions boom totally retracted.
Follow these instructions:
• turn on the diesel motor
• check the key selector (parte 2 Fig. 3.1) it’s to be in the center position
• press FN button on the main desk (Parte 9 di fi g. 3.1) and make the maneuver to
move the main boom from the control panel (part.6 Fig. 3.4).
• when the operation is ended, repeat the opposite manoeuvre to get the boom
back to horizontal position.
Information
The system stops the boom lifting automatically if the safety limit is exceeded.
To proceed with the boom lifting manoeuvre, push the self-center button on the
radioncontrol too at the same time (Fig. 3.4 part 12).
DANGER
Transfer with the lifted boom only on fl at fl oor and with slow speed. Do not
transfer on slopes even if light.
Function 2
There are particular situation during travelling, where it may be necessary to move
down the stabilizers without inserting the pins on some models, also to reduce the max
height, or in case of steep grounds.
In this case, it can be useful to lower the stabilizers to few cm from the ground, since if
the machine loose stability because of the inertia forces, the stabilizers can lay on the
ground and avoid the machine overturning.
Normally the stabilizers movement is allowed only when the articulations pins are in-
serted, or when this selector is activated.
