Secondary Steering (Option)

If the oil pressure in the steering system lowers, the
secondary steering system is activated so that steering
operation can be achieved. If the secondary steering
system is activated, the secondary steering indicator lights
and the buzzer sounds. Immediately park the machine in a
safe location. Then, contact your nearest authorized dealer.
The secondary steering can be used for 60 seconds.

steering system, if the steering function becomes

steering check switch (1) on the right console to activate
the secondary steering system. Then, immediately park and
stop the machine in a safe location.
