REMARK
When the engine is started, the selected speed remains the
same as the one set before the machine stopped.
During loading and unloading operations from a trailer, never
use the speed increase switch and always use the speed "CR".
Before switching the speed from "LO" to "HI" and vice-versa,
the machine must be at a standstill with the service brake
pressed.
The passage from "CR" to "LO" can be carried out at any time.

tor shown in the figure is displayed on the monitor.
