. OPERATION OPERATION 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.) for 3 seconds. For details, see "EMERGENCY STEERING SELF-CHECK FUNCTION (PAGE 3-124)". When the emergency steering controller detects lack of oil pressure 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 (1.2 MPH), the electric pump motor is automatically actuated 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. 3 - 124 When the starting switch is turned to the ON position, the emergen cy steering automatically carries out a self check If steering oil pressure caution lamp (red) (3) lights up, move the m achine immediately to a safe place and sto p it. Locate the cause and do not operate the machine until it has been REMARK If any function of the oil pressure system is used when the engin e is running at low speed, steering oil pressure caution lamp (red) (3) may light up for a moment, but if the lamp g oes out again soon, there is no problem.
