FOUR-WHEEL CRAB STEERING “4WS CRAB”
(to be used in building sites to position the machine for
different applications)
The four-wheel crab steering mode allows the steering wheel to
control the front and rear wheels at the same time and in the
same direction to perform cross movements to the right or to the
left.
The four-wheel crab steering can be selected only with the
machine at rest and gear selector in 1st or 2nd manual or
automatic gear. Changing over from two-wheel or four-wheel
round steering to four-wheel crab steering is possible only with
the machine at rest and after the front wheels have been aligned
(LED 5 on).
NOTE
q
With the gear selector in automatic mode it is not possible to
shift up (max. 2nd gear). 2ª).
If the selector is in manual mode and the operator tries to
engage the 3rd gear, the 2nd gear will remain engaged and the
warning light (A) on the front panel will flash to signal that the
manoeuvre is not correct.
q
Changing over from the four-wheel steering modes to two-
wheel steering is possible even while the machine is moving
and only after the rear wheels have been realigned (LED 6 on).
