The accelerator pedal Fig. 132-36 is used for continuously changing the
speed for driving forwards.
The accelerator pedal Fig. 132-37 is used for continuously changing the
speed for reversing.
Push the accelerator pedal down slowly until the vehicle starts, the speed
is increased further by pressing on the pedal.
Slowing down or braking the vehicle: Slowly reduce the pressure on the
accelerator pedal, the vehicle slows down or stops.
The vehicle speed in the:
•
transport mode is 0 to 25 km/h,
•
work mode 15/20/25 km/h according to selected engine speed.
Sweeping dry/wet surfaces
To avoid the formation of dust, circulating water and fresh water are avail-
able in vacuum sweeping. The circulating water is supplied to the suction
duct. The fresh water is supplied to the sweeping unit. The volume of fresh
water for the spray nozzles of the sweeping unit is set with the lever
Fig. 133-80.
Set the volume corresponding to the requirements.
•
Less dust formation at the rotating brushes – reduce fresh water
volume with the lever.
•
Severe dust formation at the rotating brushes – increase the fresh
water volume with the lever.
If no circulating water is available, fresh water can be switched on option-
ally for the suction duct with the lever Fig. 133-79.
Note
Dry leaves can be swept best of all at medium suction fan
speed. The suction power is sufficient and the coarse sieve
on the suction fan of the dirt hopper does not clog so quickly.
