Stopping
In normal version release the drive bar. The machine
decelerates and comes to a stop, the drive only
controlled by drive bar the other functions main brush
and side brushes are controlled by key switch .
In carpet version upon releasing the drive bar, the
machine decelerates and comes to a stop, all functions-
drive, main brush and side brush are controlled by drive
bar, when released, all functions are stopped after a
delay of 5 seconds to negotiate around corners.
Vacuum sweeping
Ensure sufficient ventilation when sweeping
indoors! It is forbidden to sweep up dust which
represents a health hazard!
ŸCheck the machine.
MACHINE OPERATION
Before starting up
ŸCheck the charge status of the battery and
recharge, if necessary.
ŸCheck the fill level of the dirt hopper and empty them,
if necessary.
ŸCheck the levels of wear on the rotary broom and
side broom.
ŸCheck the ergonomic position of the handlebar and
readjust it, if necessary.
The machine is a manually operated machine with a
drive for the dry cleaning of hard floors and hard carpets.
The side broom, located on the right-hand side of the
machine, sweeps the dirt away from corners and edges
into the path of the main rotary broom. The rotary broom
sweeps the dirt into the dirt hopper using the overhead
throw method. The particulate matter is forced against
the panel air filter by the suction turbine and filtered out
there. Only dust-free air is fed back into the ambient air.

protect the battery against total discharge, the machine
is provided with a total - discharge signal transducer
(TSG) which indicates the battery status during the
charging process and discharging.
The machine must not be used in domestic or
office areas.
Note: The machine should be used only to clean
carpets not more than 5 to 6 mm in thickness.
Switching On
The motor must not be started when the
hood is open! Risk of injury through belt
drive and rotating fan!
ŸSet the key switch to Position 1.
When the electrical system is powered On:
ŸUse your fingers to pull the drive bar against the
handlebar.
ŸSteer the machine with the handlebar in the required
direction.
This machine is applicable for dry
sweeping only.

empty as necessary, refer to paragraph ”Emptying
the dirt hopper”.
Do not overload the dirt hopper! This can affect the
stopping distance. Caution, particularly when
sweeping up dirt such as metallic chippings!
Tip out the dirt hopper from a low height when
emptying to prevent dust swirling around! If
necessary, pay attention to the wind direction and
evade any clouds of dust! Health hazard!
Switching off
ŸTurn the key switch to Position 0.
After finishing work
ŸOperate the shaking device.
ŸEmpty the dirt hopper.

Adjusting the drive belt
If you notice that the rear wheel shaft is no longer driven
properly, it is possible that the tension of the drive belts is
no longer sufficient or the running surface of the friction
wheel is worn (distance between wheel and running
surface > 1mm).
ŸLoosen the screw connection in the friction wheel
crank.
ŸTension the belt which leads to the rear wheel shaft
by moving the friction wheel crank in the slot using an
appropriate tool.
ŸTighten the screw connection in the friction wheel
crank.
ŸCheck the belt tension with an appropriate
measuring instrument (belt tension 75±5 Hz).
The friction wheel thereby lies against the drive
shaft.
ŸTurn the hexagon nut so far on the eye bolt until the
tension spring tensions and the friction wheel
retracts 1-2 mm from the drive shaft.
ŸTurn the hexagon nuts one revolution further.
ŸComplete any fine adjustment using the bowden
cable adjusting nuts on the handlebar: turn the
adjusting nuts, so that the distance between friction
wheel and drive shaft is between 0.4 and 1 mm.

MACHINE OPERATION
Changing the Main Rotary Broom
The rotary broom must be checked weekly and changed
in the case of wear. A new main rotary broom has a
diameter of 250 mm. When a main rotary broom has a
diameter of only 200 mm, it must be replaced with a new
one. The main rotary broom is comprised of two rotary
broom segments which are fixed to the rotary broom
shaft by the screws . Pay attention that the bristle pattern
on the rotary broom is always arranged in a V-shape in
the direction of driving so that the dirt is guided to the
center of the rotary broom.
ŸTip the machine to the rear.
- Before tipping the machine, the battery must
be removed.
- Before the machine can be tipped back, the
handlebar must be adjusted to a vertical
position.
ŸFirst of all, disassemble the two adjacent rotary
broom segments : Loosen the screws and remove
the rotary broom segments.
ŸThen turn the rotary broom shaft 180º by hand and
disassemble the two remaining rotary broom
segments.
ŸAssemble two new rotary broom segments in the
reverse sequence. When doing so, pay attention
that the rotary broom segments are installed on the
guide pins of the rotary broom shaft and screw to
facing rotary broom segments firmly to each other.
ŸTip the machine back up again.
ŸInstall the battery again in the machine.
ŸAfter changing the rotary broom, readjust the
sweeping pattern as necessary.
Setting the sweeping pattern
In the case of broom wear, and after changing the rotary
broom, the sweeping pattern must be readjusted.
ŸPush the machine onto a dusty surface.

ŸSwitch the machine on and allow the rotary broom to
rotate for a short time while at a standstill.
ŸSwitch the machine off.
ŸTip the machine up at the front a little and pull the
machine back a short way.
ŸExamine the sweeping pattern (broom stroke)
produced on the dusty ground: The width of the
sweeping pattern must be approx. 50 mm. The
borders of the sweeping pattern must be parallel.
ŸOpen the hood.
ŸAdjust the height of the rotary broom by means of the
control knob.
ŸClose the hood.
ŸRepeat steps 1 to 8 until the adjustment is correct.
Changing the sealing strips
The rotary broom is surrounded by four sealing strips: a
front apron, two rear aprons (front and rear) and two
side aprons. The four sealing aprons must be checked
weekly and changed in the case of wear.
ŸTip the machine to the rear.
Before tipping the machine, the battery must be
removed. Before the machine can be tipped

height onto a level, solid surface. Be careful not to
damage the filter ribs!
The ground must not have any surface
irregularities. Do not drop the panel air filter
onto the ground at a slant.
Never install panel air filters which have
damaged filter ribs!
Replacing the sealing strips
If the panel air filter is removed, check the self-adhesive
sealing strips for signs of damage. Damaged sealing
strips must be replaced:
ŸPull off the damaged sealing strips.
ŸClean any residual adhesive from the surfaces on
which the sealing strips have to be assembled.
ŸAssemble the new sealing strips.
Inserting panel air filters
ŸInsert the thoroughly cleaned or new panel air filter
from the correct side in the filter support frame.
Pay attention to the labeling on the side of the
panel air filter.
ŸReplace the filter cover
ŸClose the bottom filter cover locks: Pivot the hinged
locks over the edge of the filter cover.
