transmission, press switch (25) on the side of the lift arm con-
trol lever knob. The speed range displayed on the transmission
indicator on the main monitor is then fixed and the HOLD dis-

later.

There is a step lamp switch on the battery box and the left con-
sole next to the operator's seat. It is possible to turn the lamp
