q
Track gauge adjustment control
WARNING
q
Select the narrow track gauge only when the machine must travel in small spaces. For normal applica-
tions and digging operations, always select the wide track gauge.
q
Adjusting the track gauge on slopes is dangerous, since this may affect the lateral stability of the ma-
chine. Therefore, it is advisable to adjust the track gauge on level surfaces.
q
When the track gauge is narrowed completely, also the lateral stability of the machine is reduced. In
work sites where the machine runs the risk of overturning, widen the track gauge and pay the utmost at-
tention during travel.
q
The adjustable track control is not locked, even if the safe-
ty device lever is in locking position. Therefore, do not
touch the control lever if no operations are being carried
out with the adjustable track.
q
Before using the blade/adjustable track gauge lever, check
the position of the switch.
q
Set the blade/adjustable track gauge switch to the track gauge
adjustment position.
To adjust the track gauge, shift the lever positioned to the right
of the operator seat forward or backward.
IMPORTANT
q
If there are obstacles that prevent the adjustment of the
track gauge, remove them or place the machine on a level
surface, in order to be able to find the correct position for
the adjustment.
q
If the tracks are dirty with mud, clean them thoroughly be-
fore adjusting the track gauge.
q
It is possible to vary the width of the blade to adapt it to the
track gauge. To adjust the blade width from wide to narrow,
remove the pin and rotate the extended portion of the blade
in the direction indicated by the arrow, then align the two
holes and insert the pin.
q
To adjust the blade width from narrow to wide, carry out the
same operations in the reverse order.
