Track gauge width:
Max. 1320 mm
Min. 1000 mm
3.14.1 HOW TO USE THE VARIABLE
TRACK GAUGE
DANGER
• If the track gauge width is modified on slopes, the lateral
stability of the machine may change. For this reason it is
advisable to carry out this operation on level surfaces.
• When the track gauge is reduced as much as possible, the
lateral stability of the machine is reduced as well.
In working sites where the machine may overturn, widen
the track gauge and be careful during travel.
CAUTION
• Always raise the machine before modifying the track
gauge. If the machine is not raised, the shoes and the hy-
draulic motors may get damaged.
1 - Stop the machine on a level surface.
2 - Raise the machine by means of the work equipment and the
blade, so that the lower shoes are at a distance of approxi-
mately 5-10 cm from the ground.
3 - Press the button (1) positioned on the left joystick lever (see
"3.3.3 pos. 7 VARIABLE TRACK GAUGE CONTROL PUSH
BUTTON").
4 - Shift the blade control lever (2) forward to widen the track
gauge or backward to narrow it (see "3.3.5 pos. 6 BLADE
CONTROL LEVER").
