9.6 Emergency manual operation of electro-hydraulic forced steering axle
system SES
In case of a malfunction, the forced steering axle
system automatically switches over to passive
steering, thus making focused reversing
impossible.
Lock the steering axle(s) by means of the
emergency manual operation function, in order to
be nevertheless able to move the vehicle
backwards (over short distances!). The wheels
should be in a straight line then.
Emergency manual operation is actuated at the
electro-hydraulic control block (1).

Lock steering axle(s)
1.

Secure tractor and machine against accidental starting and rolling.
2.

Use a hexagon key SW 3 to screw in the grub screws(1) Fig. 172 / Fig. 173.
Screw in the grub screws only finger-tight (max. 2 Nm)! Otherwise, the valves may interlock and
the emergency manual operation function can no longer be released.
Steering axle/s locked.
Only lock steering axles via the emergency manual operation
function in case of a malfunction, e.g. for short
reverse travel!
Unlock the steering axle(s) again as soon as the malfunction has
been remedied!
Long drives with 2 locked steering axles cause increased wear on
tyres and chassis, in particular on the tridem chassis.
