4 Putting into operation
NOTICE
Risk of technical damage!
Due to the higher viscosity in the hydraulic system and the
engine oil circuit at temperatures below 0 °C, major
technical damage can be caused if the engine speed is
increased suddenly.
Do not start the engine under any circumstances by
towing the machine. This can cause serious damage to
the hydraulic system.
Stop the engine immediately if the warning lights do not
go out or if they illuminate with the engine running. Ensure
that the malfunction is rectified immediately. Do not put
the machine into operation before rectifying the
malfunction.
Do not suddenly stop the engine after running it under full
load. Let the engine run at idling speed for about 3
minutes so that the temperature can stabilize, and then
stop it.

Information
The operator seat is equipped with an operator presence
switch that prevents activating the drive if the operator is
not seated on the operator seat!
If the load on the operator seat is removed with the starter
switched on or the engine running, a warning signal
sounds after 3 seconds, and the drive is switched to
neutral after another 2 seconds.
This also applies to machine travel!
