5. Blade/adjustable track gauge selection switch
WARNING
q
Use the narrow track gauge only when it is necessary to go
through narrow passages or when there is no other choice.
For normal applications and digging operations, always se-
lect the wide track gauge.
q
Avoid adjusting the track gauge when the machine is work-
ing on a slope: the machine may lose stability and over-
turn. Always adjust the track gauge on level surfaces.
q
When the track gauge is narrowed completely, also the lat-
eral stability of the machine is reduced. In work sites where
the machine runs the risk of overturning, always widen the
track gauge and pay the utmost attention during travel.
q
The control of the scraper and the adjustable track is not
locked, even if the safety device lever is in locking position.
Therefore, do not touch the control lever if no operations
with the scraper or the adjustable track are being carried
out.
q
Before using the blade/adjustable track gauge lever, check
the position of the switch.
This is a two-position switch and allows the operator to choose
between using the blade and adjusting the track gauge.
Adjustable track gauge (A): when the switch is in this position, it
is possible to adjust the track gauge.
Blade (B): When the switch is in this position, it is possible to use
the blade.
For further details on how to use the blade and adjust the track
gauge, (see "3.2.3 pos: 5. Blade/adjustable track gauge lever").
