WARNING

The hydrostatic transmission calls for high engine speed, giving the main hydraulic pump its

maximum drive and braking performance. For this purpose :

adjust the accelerator lever progressively to an engine speed of a minimum of 1800 to 2000

2-8 WHEEL STEERING

TWO WHEEL STEERING

The steering is of the hydrostatic type. If the pump fails to work, the steering can be operated in a

closed circuit by means of the ‘’ORBITROL’’ distributor.The pump also operates the hydraulic cir-

cuit by means a priority valve.

With a distributor, 2 position pick-ups, a switch and a pedal, the 2-wheel steering functions can be

used.

- Set the switch to ‘AUTO’.

- Turn the steering control so as to place the rear wheels in

straight position; the‘REAR’ warning lamp goes on.

In this operating mode, only the front wheels can steer and

the rear wheels remain straight

2- wheel steering is operating
