dust).
 Switch off the blower fan. The electric filter cleaner is
operated automatically for approx. 10 seconds.
 Switch on the blower fan again.
Emptying the waste hopper
!
Important information
Injury hazard!
No person or animal should be allowed to remain in the area
tra ersed by the hopper while it is being emptied.
Danger of being crushed!
Do not reach into the shafts and linkage of the emptying
mechanism.
Do not stand under the raised hopper.
Risk of sweeper topp ing over!
If the sweeper is standing on a slope with a gradient of more
than 5 %, it could topple o er while the hopper is being
emptied. The hopper should therefore only be emptied when
the gradient at the location where the sweeper is standing
is less than 5 % for the direction in which it is facing.
 Stop the sweeper.
 Raise the main brush .
Note: Following steps can only be performed with the
sweeper set to two-handed operation.
 Raise the waste hopper, 1 + 2. +
When the hopper has reached the required height dri e
backwards towards the discharge container.

18
English
Note: The hopper can only be emptied when the supporting
arms have reached a horizontal position. To avoid the dust
billowing up when the hopper is emptied, the waste hopper
should be lowered as far as possible into the discharge
container.
 Tip the waste hopper
1 + 3 +
When you release the button for tipping the waste
hopper, the waste hopper returns to its home position
automatically.
 Raise the waste hopper, dri e away from the discharge
container and retract the waste hopper.

Typica app ications
!
Caution whi e sweeping!
Do not sweep up packing bands, wires or similar items,
otherwise the sweeping mechanism will be damaged.
Do not sweep any burning/glowing objects.
For c eaning even surfaces
 set the le er for the main brush roller to the middle
position (minimum brush wear).
For c eaning uneven surfaces
 set the le er for the main brush roller to the lower
position (increased brush wear).
 switch on blower fan for dust extraction
 for cleaning right up to the edges  lower the side brush
.
If you are sweeping up fine dust, use the side brush as
little as possible as it will increase the amount of dust
stirred up by the sweeper.
If the side brush encounters an obstacle, it automati-
cally swi els back inside the outer contours of the
sweeper. A oid collisions!
 To protect the filter from getting damp when sweeping
wet surfaces, switch off the dust extraction
Picking up larger items (sticks, tins, etc.)
!
Caution!
When the bulk waste flap is open, stones or grit could be
thrown forwards by the main brush. Make sure therefore
that when you open the flap no persons, animals or
property are endangered.
 Open the bulk waste flap by hand.
 Dri e o er the items to be picked up, at low speed and
with the bulk waste flap open.
Note: In order to avoid stirring up dust unnecessarily, the
bulk waste flap should be open for short periods only.
