4 - FRONT LOADER CONTROL LEVER
WARNING
q
Before carrying out any manoeuvre with this lever, the
operator must be seated in the driving position, with
fastened safety belt.
q
If the loader control lever has to be used during travel,
avoid any abrupt and quick movement that may affect
the balance of the machine and make it difficult to drive.
q
If it is necessary to leave the machine on a slope, take
all the precautions aimed at preventing any uncon-
trolled movement of the machine itself.
(See "3.7 PARKING THE MACHINE").
q
Before leaving the operator’s seat, lower the bucket to
the ground and engage the safety lock before stopping
the engine.
The front loader control lever (4) is positioned on the opera-
tor’s right and controls the lifting and lowering of the arm and
the folding and dumping of the bucket according to the orthog-
onal movements listed below.
If the machine is properly equipped, the shifting of the lever to
position
E (one click) sets the loader to a free, or floating posi-
tion, that is, to a position in which it can automatically follow
the undulation of the ground.
Shifting the lever (4) 45° towards the axis of the machine (
F )
activates the “Return-to-dig” device, which controls the lower-
ing of the loader arm and at the same time folds the bucket in
loading position.
As soon as the bucket touches the ground, the “Return-to-dig”
device is disconnected and the machine returns to normal op-
erating conditions.
