cylindrical brush
NOTE

(disc brushes, suction unit)
► Reduce the sweeping speed under 25 km/h

Start the vehicle engine
 Start auxiliary engine
NOTE
The cold diesel engine warms up automatically
before it can be switched to full load capacity.
The engine controller automatically ensures
that this is the case.
Sweeping in daily operation:
Sweeping without water in the suction hose is
not permitted (except if in wet weather or rain).
The water provides optimum dust separation when
picking up debris.
Sweeping in icy conditions:
When sweeping with the machine in icy conditions -
usually without water - the machine may be subject
to greater wear. The lack of water intake in the debris
pick-up area can lead to increased dust emissions.
You should therefore sweep at a reduced speed.

Use option switches to select the functions of
your choice (disc brushes, cylindrical brushes,
spraying unit, suction unit and path marker).
 Setting the brush speed (optional)
 Setting the diesel engine speed.
 Use the joystick on the control panel to raise
and lower the selected units or switch them on
or off
 Set vehicle in motion. Driving speed must be
adapted to the respective debris levels on the
road surface.

Debris exceeding a certain size (suction nozzle
width 70 mm with open coarse dirt flap) cannot be
picked up by the machine. It could damage the
pick-up unit.
 Empty and clean the hopper after use.
