Inside controls
The setting controls for the electronically controlled hy-
draulic lift are located to the right of the driving seat (see
page 33) and consist of four knobs:
Lift controls
1 Height limit adjustment control.
• Turn the knob completely clockwise to set the maximum
arm lift limit.
• Turn the knob completely anticlockwise to set the mini-
mum arm lift limit.
2 Lift arm drop rate adjustment control.
• Turn the knob fully clockwise to set the maximum arm
drop rate.
• Turn the knob fully anticlockwise to set the minimum
arm drop rate.
3 Lowering limit adjustment control.
• Turn the knob completely clockwise to set the maximum
arm lowering limit.
• Turn the knob completely anticlockwise to set the mini-
mum arm lowering limit.
4 Position/draft sensitivity control:
• This knob enables adjusting the mixed position/draft
sensitivity control mode.
• Turning the knob anticlockwise gradually reduces the
extent and frequency of the corrections made by the lift
in response to the changes in resistance provided by
the ground as the implement moves forwards.
• When this knob is turned completely anticlockwise, the
lift works only in position control mode.

NOTE: With the drop rate control knob (2) turned com-
pletely anticlockwise, onto the padlock symbol, the lift will
remain locked in the position it had at that moment, irre-
spective of whether it was moving or not. In this condi-
tion it is possible to lift the implement, but not to lower
it. Turning the knob clockwise, towards the hare symbol,
progressively increases the drop rate.
When the lift is at work, the drop rate is regulated by the
knob
(2) .
NOTICE: When travelling on roads, turn the arm drop rate
control knob (2) completely anticlockwise, onto the tor-
toise symbol and press the up/down switch onto the UP
position
(A) fig. 3 . The indicator (2) fig. 2 will begin to
flash to signal that transport mode is activated. By oper-
ating controls
(2) fig. 1 and (2) fig. 3 the lift will be dis-
abled and will need to be reset, following the procedure
described on the next page.
