OPERATING MANUAL
Seat switch
The seat switch is located in the seat cushion.
If the driver is not sitting on the seat, the seat switch is deactivat-
ed and the operation of the machine is restricted in one of the
following ways – blocking of engine start, blocking of moving
o, stopping of the machine or switching o the engine.
These restrictions vary depending on:
• the time period for which the seat switch is deactivated,
• the position of the travel control (if it is in the parking brake
“P” position or outside this position)
Engine start blocking
If the driver is not sitting on the seat, engine start is blocked un-
less the travel control is in the parking brake position (P).
To enable engine start, set the travel control to the parking
brake position (P).
Movement blocking
If the driver is not sitting on the seat, moving o is blocked. In
this case, moving the travel control out of the parking brake (P)
position immediately switches o the engine with a 5 second
delay.
To enable engine start, sit on the seat and set the travel control
to the parking brake position (P).
Machine stop
If the driver leaves the seat for more than 5 seconds and less
than 10 seconds when the travel control is not in the parking
brake position (P), the machine stops. The traction force of the
machine is o, vibration is o and, after a delay, the parking
brake engages (P).
To be able to move o again, sit on the seat and set the travel
control to the parking brake position (P).
Engine shutdown
If the driver leaves the seat for more than 10 seconds when the
travel control is not in the parking brake position (P), the engine

trol to the parking brake position (P).
