Steering
■
To change the direction of travel, select the appropriate position of the steering levers.

Brakes
The hydrostatic drive system acts as a brake, and slowly decelerates the snow groomer to a stop:
■
To brake the vehicle, slowly push both steering levers to neutral position or gradually release
the foot from the accelerator pedal.
Driving forwards / backwards
Operating the accelerator pedal increases the speed of the engine and sets the snow groomer in mo-
tion. In order to reduce the speed and stop the snow groomer, gradually release the foot from the ac-
celerator pedal. The engine speed and vehicle speed are reduced and the snow groomer comes to a
halt. That way, the snow groomer slows down due the engine's braking effect only.
On steep slopes, when parking or during emergency braking, the parking brake must be activated by
pressing the Emergency OFF switch.
To drive at reduced speed without reducing the engine speed, the vehicle speed rotary switch on the
joystick can be used to bring down the forward or reverse ground speed until the vehicle comes to a
standstill. This is suitable, for example, when working with the snow plough.
The warning buzzer and rear work lamps are automatically activated for reverse travel.
■
To move forwards, push both control levers from the zero position to the front at the same
time.
■
To move backwards, pull both control levers from the zero position to the back at the same
time.
The following points must also be observed when reversing:
■
When reversing, take care to prevent the snow groomer from colliding with a snow wall.
■
Never reverse while automatic raising of the rear attachment is switched off.
■
Reversing is only to be used after the vehicle has been brought to a complete standstill. The
rear attachment is automatically raised and the cutter shafts are stopped.
For night operations in populated areas, the warning buzzer can be temporarily switched off. The de-
activation can be performed in the menu. Only use this function if special circumstances require it. If
the warning buzzer is deactivated, pay particular attention that no persons are in the travel area of the
snow groomer.
