switch OFF before starting the inspection and maintenance operation. z When carrying out leveling work, turn the E.C.S.S. switch OFF. The E.C.S.S. is a device that uses the hydraulic spring effect of an accumulator to absorb the vibration of the chassis during travel and allows the machine to travel smoothly and at high speed. This switch (7) is used to turn the E.C.S.S. ON and OFF. a A Position (a): ON The pilot lamp (A) lights up and the E.C.S.S. is actuated. Position (b): OFF The E.C.S.S. is not actuated.
b REMARK The travel damper is automatically actuated when the travel speed becomes more than 5 km/h (3.1 MPH); when the travel speed goes below 4 km/h (2.5 MPH) it is automatically disengaged. GK032123 WA150-5H – VEAM934100 3-33 WARNING WARNING
