Emergency steering
CAUTION
!
Never actuate the emergency steering except during emer-
gencies or when checking the function.
!
The emergency steering can be used continuously for a
maximum of 60 seconds. Operating it continuously for more
than 60 seconds may damage the system.
!
When using the emergency steering, travel at a speed of
less than 5 km/h.
!
If the steering becomes heavy, keep the emergency steering
switch pressed, move the machine immediately to a safe
place, then stop the machine.
During emergencies or when stopping the engine to check the
function, press emergency steering switch (1).
Emergency steering pilot lamp (green) (2) will light up and the
steering can be operated.
The emergency steering system is provided to enable the
machine to be steered under the following conditions.
!
The starting switch is at the ON position.
!
The steering oil pressure is low or there is no pressure.
(When the engine has stopped or there is a failure in the
steering oil pressure pump, etc.)
When the starting switch is turned to the ON position, the emer-
gency steering automatically carries out a self check for 3 sec-
onds.
For details, see "Emergency steering self-check function
(3-127)".
When the emergency steering system detects lack of oil pres-
sure in the steering system, steering oil pressure caution lamp
(red) (3) and central warning lamp (4) light up, and the alarm
buzzer sounds intermittently.
When this happens, if the machine is traveling at a speed of
more than 2 km/h, the electric pump motor is automatically actu-
ated and emergency steering pilot lamp (green) (2) lights up.
Steering oil pressure caution lamp (red) (3) lights up to inform
the operator that there is a failure in the steering system.
If steering oil pressure caution lamp (red) (3) lights up, move the
machine immediately to a safe place and stop it.
