3. Unpacking and Assembling
Let the box stand on the pallet. Cut the front side open and let the machine roll
over the side of the box which has been folded down (see Figure) so that the run-
ning wheels are still standing on the pallet.
In this position, clip the side brushes which are on the dirt container under the side
brush plate (in the front exterior portion of the machine) (see Figure). Apply light
pressure to twist the brushes upwards until you can feel them lock into place. Note:
do not tip over the machine in this process: there is the danger of battery acid
running out.

First roll the machine from the box and from the pallet.
Afterwards, put the steering handle in the upright position, pull it downwards into
the two tappets completely (see Figure) and tighten it with the two thumb screws.
Note: before you carry out the following steps, please ensure that the safety switch
on the steering handle is put in position "0" (see Figure).
Remove the main-cover of the machine unlatching device with the tool supplied in
the reach of the dirt collector after the dirt collector has been removed. After open-
ing up the cover, the positive pole of the battery can be slipped on and be tight-
ened with a spanner (SW 13) (It was removed for reasons of safety during transpor-
tation). Finally, replace the cover latching device again immediately.
4. Starting Up/Operating
After the machine has been assembled, it is immediately ready for operation.
First of all, the two lateral brushes should be lowered. For this purpose, push the
thumb washer forward (see Figure) with your foot until the brushes just touch the
floor.
It is possible to adjust the height of the main sweeping brush using the adjustment
handle on the left side of the machine (under the dirt collector) (see Figure). Please
ensure that the brush tips only touch the floor lightly. If the brushes are adjust too
low, this increases the wear on the brushes and the gear components as well as the
power consumption. Position 1 - the highest brush position (for new, unworn roll-
ers), position 5 - the lowest brush position (for worn brushes or very uneven floors
for a short period of time).
Put the toggle switch on the steering handle in position "I" (see Figure).
Afterwards, the LED's over the switch indicate how much of a charge there is in the
battery. If the green diode is lighted up, the machine is ready for operation. If the
yellow diode is lighted up, go to the loading station. If the red diode is lighted up,
the machine should be switched off immediately to keep the battery from losing its
charge. Put the toggle switch to "0" to shut the machine off. This switch also serves
the purpose of protecting against overloading during power transmission. If the
motor load become significantly higher, for instance as a result of sweepings get-
ting blocked or excessive resistance in the drive, the switch jumps into position 0.
After eliminating the malfunction, the machine may be restarted.

Steering drive:
The machine starts moving when you carefully pull the steering handle towards
you. Check the behaviour of the steering drive especially when it is used for the first
time so that the machine remains under control. We recommend that you loosen
your grip on the steering handle slightly when going around curves to lower the
speed in the curve. You will quickly notice that it is easy to operate and move the
machine with or without using the steering drive. If there is more dirt, you should
push the machine over the dirty place more slowly to achieve the optimum clean-
ing effect.
In order to move it backwards, loosen the steering handle and pull the machine in
the desired direction.
Cleaning filters:
There is a handle in the area of the handle of the dirt container. This should be
moved a number of times (see Figure) every time before you empty the dirt collec-
tor with the motor shut off. This sets a vibration mechanism into motion so that the
loose dirt which is sitting between the lamellas falls directly into the dirt container. If
there is stubborn dirt, clean the filter with a brush or remove the filter and tap
slightly.
Emptying the dirt collector:
Always take the dirt container in both hands (see Figure). You should put one hand
in the front handle area in the middle of the machine. Put the other hand on the
upper edge from behind.
Lift the container upwards from behind.
It is easiest to empty it into a rubbish bin over the side edge (see Figure).
After use:
When you have finished sweeping, shut off the machine. In order to alleviate the
load on the lateral brushes, the side brushes have to be put up using the thumb
washers every time after it is used (see Figure).
Charging the battery:
The charging socket is on the lower side of the operating console (see Figure).
This is where you should insert the charging plug. We recommend that you always
leave the machine on the battery charger when it is not being used. This will guar-
antee that you will always have a machine which is ready for operation. Put the
switch of the battery charger included on "normal" and observe the information of
the battery charger manufacturer.

Belt check for defects and voltage
sweeping roller and side brush check for wear
Troubleshooting:
A.) the motor doesn't start
possible reason potential solution:
1.) the battery is not charged Charge the battery
2.) the overload protection jumps out the drive is blocked or correct brush roller
(see B.2)
3.) interruption in the electrical line check the line (see the wiring diagram) and
repair the connection if necessary
B.) the results of sweeping are not satisfactory
possible reason potential solution:
1.) the dirt container is overfilled empty the dirt container
2.) sweepings are caught in the swee-
ping brush
take out the dirt container and remove the
object
3.) the roller RPM's are too low see defect A.)
4.) height adjustment of the sweeping
brush is wrong
adjust the height in such a fashion that
only the tips of the bristles touch the floor
C.) the running time of the machine is insufficient
possible reason Potential solution:
1.) the battery has little power check the battery and refill acid if neces-
sary and charge, exchange battery if nec-
essary
2.) the power consumption is too high check the main brush for height adjust-
ment and to see if they are blocked
3.) the battery is insufficiently charged check to see if the battery and battery
charger are functioning perfectly
D.) the brushes do not rotate
possible reason potential solution:
1.) the belt of the power transmission
unit is defective / has slipped off
check all of the belts on the machine (7
pieces)
2.) sweepings are caught in the swee-
ping roller
see B. 2
E.) the steering drive is not functioning / not properly
possible reason potential solution:
1.) the tooth belt is defective / has
slipped off
see D.1
2.) the friction clutch is not engaging adjust the setting mechanism on the han-
dle console (part 95)
F.) too much dust develops
