12-3-2 Rear steering
(611A-0070-0E)
(1) Releasing the rear steering lock
1) Stop the machine.
2) In order to release the rear steering lock, set the rear steering lock/release switch to the release side. While it is
releasing, a buzzer sounds and the rear steering lock release confirmation indicator lamp flashes rapidly. When
the buzzer stops and the rear steering lock release confirmation indicator lamp lights steadily, the release process
is complete and rear steering is possible, independent of the front wheel steering.
・
Lock the rear steering before you stop the engine.
・ Lock the rear steering for driving on roads.
・ Check that there is nobody near the rear wheels before you lock the rear steering.
・
As a rule the machine should be at rest for rear steering locking/releasing.
・ If you cannot lock the rear steering because the rear steering lock pin will not fit into place,
drive the machine at extremely low speed while locking the steering.
If the machine moves at more than 7km/h at this stage, the misoperation warning buzzer will
sound.
・
If you drive the machine at more than 7km/h by mistake to lock or release the rear steering,
the rear steering lock release confirmation indicator lamp will flash and the misoperation
warning buzzer will sound. Reduce the driving speed to 7km/h or less and return the rear
steering lock/release switch to the original position. Then try again to lock or release the rear
steering.
・
A pressure of at least 500kPa (5kgf/cm
2
) in the compressed air tank is required.
If you attempt this operation while the low air pressure warning lamp is lit, the rear steering
lock release confirmation indicator lamp will flash and the misoperation warning buzzer will
sound. Raise the pressure in the compressed air tank to more than 500kPa (5kgf/cm
2
) and
return the rear steering lock/release switch to the original position. Then try again to lock or
release the rear steering.
・ When there is a malfunction in any device related to rear steering or when the rear steering
emergency switch is "ON", the rear steering mode cannot be switched. The misoperation
warning buzzer will sound.
・ If it is impossible to release the rear steering lock, move the machine forward slightly. Then
move the rear steering lock/release switch again.
・ If the machine moves at a speed of more than 15km/h with the rear steering released, the
warning buzzer will sound and the speed will be reduced automatically.
・ Take particular care when moving down a slope.
