Emptying the
waste container
Some important points in advance
Injury hazard!
Make sure that there are no persons or animals standing at the back of the
sweeper, in the immediate vicinity of the waste container, while it is being
emptied.
Danger of hands become trapped!
Keep hands well away from all parts of the emptying mechanism.
Danger of toppling over!
If the sweeper is standing on a slope with an incline greater than 5%, it
could topple over while it is being emptied.
Do not empty the waste container while the sweeper is standing on a slope
unless the incline is less than 5%, as seen in the direction of travel.
n Stop the sweeper.
n Raise the brush roller.
(The waste container cannot be emptied while the brush roller is lowered.)
n Swivel the waste container upwards.
When the waste container has reached the required height:
n Tip out the contents.

English
Operating instructions for users
n Swivel the waste container downwards.
Note:
The waste container cannot be fully retracted until it has been tipped all the
way back into its original position.
Caution while sweeping!
Do not sweep up any packing bands, wire or similar objects, as these could
cause damage to the sweeping mechanism.
Typical applications
Sweeping Dry Floors
Two different main brush settings are possible:
a) Stationary main brush – sweeping pattern is rigidly fixed, see “Setting
Sweeping Pattern” (in chapter on maintenance),
b) Floating main brush – with its deadweight the main brush rests on the
floor and adapts to floor irregularities
Resetting to “Floating Main Brush”
n Raise main brush
n Open and stay cover
n Reset adjusting screw from position 2 into position 1
For slight and normal dirt accumulation:
n For large-floor cleaning –
Lower main brush 1
– Press button
n To switch on dust pick-up
– Move up lever 2
Additionally
n For cleaning up to edge –
Lower side brush 3
– Press button
Note:
The side brush only works when the main brush roller has been lowered.
At regular intervals:
n Clean the filter (see earlier description).
n Empty the waste container (see earlier description).
Notes:
In order to achieve the best cleaning results, the maximum travelling speed is
automatically reduced from 15 km/h to 8 km/h when the brush roller is lowe-
red.
If you are sweeping up very fine dust particles, use the side brush as little as
possible. Even more dust will be created otherwise, as the vacuum unit is not
effective round the side brush.
If the side brush hits an obstacle, it automatically retracts into the side of the
sweeper.
During the time that the sweeper is operating, the filter should be cleaned
approx. every 15–30 minutes (depending on the amount of dust).
Sweeping a damp or wet floor surface
Follow the same basic procedure as for sweeping dry surfaces. To protect the
filter from moisture:
n Switch off the vacuum unit.
– Push the lever downwards.
At regular intervals:
n Empty the waste container (see earlier description).

at the charging station. Before the operator carries out any work on
batteries, he/she must have received proper instruction from a suitably
qualified person.
Wear safety goggles and protective clothing when working on batte-
ries. Observe accident prevention regulations, as well as DIN VDE
0510, VDE 0105 Part 1.
Smoking is forbidden!
Make sure that there are no naked flames, other source of heat or
sparks in the proximity of the battery, otherwise there is a danger of
explosion or fire.
If electrolyte comes into contact with skin or eyes, rinse the affected
area with plenty of clean water. The metal parts of battery cells are
permanently live. Therefore do not place any tools or other objects on
top of the battery.
Explosion and fire hazard! Avoid short-circuits.
Warning! The metal parts of battery cells are permanently live. There-
fore do not place any tools or other objects on top of the battery.
Electrolyte is highly corrosive. Under normal operating conditions it is
not possible for anything to come into contact with the electrolyte. If
the battery housing is destroyed, the bound electrolyte that leaks out
is just as corrosive as liquid electrolyte.
Return to manufacturer!
Exhausted batteries bearing this symbol are a re-usable resource
which should be recycled accordingly. Exhausted batteries that are not
intended to be recycled must be disposed of as hazardous waste in
compliance with all relevant regulations.
Checking the electrolyte in the battery
Check the acid concentration in electrolyte-filled batteries at regular intervals.
Make sure the battery is fully charged before it is tested.
If required:
n Top up with distilled water until the level of fluid is approx. 1 cm above the
lead plates.
Charging the battery
Note:
Only use a regulated charger that is suitable for use with starter batteries and
is capable of delivering a charging current of 4–6 A.
n Stop the sweeper and remove the ignition key.
n Tilt the seat forwards.
n Connect the positive terminal (red clamp) to the charger.
n Connect the negative terminal (black clamp) to the charger.
n Connect the charger to the mains and switch it on. The charging time is
specified by the manufacturer of the charger.

Replacing sealing strips
The sealing strips fulfil an important function. They maintain the partial vacu-
um in the area surrounding the brushes that is necessary for the sweeper to
perform properly. In so doing, they ensure that no dust is expelled while the
machine is sweeping.
Damaged or worn out sealing strips should be replaced immediately.
n Stop the sweeper and turn off the engine.
n Remove the hex screws and pull off the sealing strips.
n Insert new sealing strips and align them as follows.
Adjust the side strips so that they clear the ground by 3–5 mm.
Adjust the strip at the front so that when the sweeper is travelling for-
wards, it bends backwards by 20–40 mm and the strip at the rear so that it
bends backwards by 0–20 mm.
Direction of travel
n Tighten the hex screws.
Replacing the side brush
n Stop the sweeper and turn off the engine.
n Raise the side brush.
n Undo the three nuts by hand.
n Remove the side brush.
n Attach the new side brush.
n Screw on the three nuts by hand and tighten securely.
Replacing the brush roller
n Stop the sweeper and turn off the engine.
Burns hazard!
Take care not to touch the hot exhaust.
n Remove the 3 screws (Torx) and lift off the side cover.
n Remove the hand screws in the oscillating linkage.

n Remove the next three hand screws and lift off the roller cover.
n Pull out the brush roller at the side.
Note: Raise the brush roller unit before inserting a new roller.
Brush roller viewed
from above
n Insert a new brush roller, paying attention to correct alignment (see illu-
stration). The projections on the driver must slot into the recesses in the
brush roller.
n Continue with assembly in reverse order of removal.
Direction of travel
Replacing fuses
n Stop the sweeper and switch off the engine.
n Open the bonnet.
n Remove the cover.
n Replace any blown fuse with one with the same rating. There are spare
fuses in the fuse box.
Note:
If the same fuse blows several times, this is a sign that there is a fault in the
electric circuitry. Locate and repair the fault (see section on Troubleshooting).
Replacing the dust filter
Dust filters should be inspected for signs of damage every 50 operating
hours. A damaged filter allows dust to be blown into the engine compartment
and surrounding area. A significant build-up of dust at the air exit from the
fan is an indication that the filter is not properly seated or is defective.
n Raise the waste container to its max. height.
n Secure the waste container at both sides.
– Undo the screw in the side cover.
– Insert the hand screw into the locking bolt and pull it out.
n Remove the two hand screws in the preliminary filter and lift out the filter
from below.
n Loosen 2 screws on the thrust bearing and turn the thrust bearing anti-
clockwise up to the stop (1). Draw out the thrust bearing towards the rear
(2).
n Draw the filter element towards the rear and take it out to the rear (3).

Setting the Sweeping Pattern
Note:
The main brush can be reset to:
– Floating 1: With its deadweight the main brush rests on the floor.
– Stationary 2: The sweeping pattern is adjustable at the main brush.
In order to adjust the sweeping pattern reset the main brush to “Stationary”.
n Open and stay cover
n Reset main brush to “Stationary 2”
n The sweeping pattern can be altered by turning the adjusting screw.
To increase coverage – turn screw outwards
or
To reduce coverage – turn screw inwards
n Close the bonnet.
Check the sweeping pattern after making any adjustments.
n Drive the sweeper onto a dusty surface.
n Lower the brush roller and let it sweep for several seconds.
n Raise the brush roller and drive the sweeper backwards a short distance
with the bulk waste flap opened.
n The width of the contact area should be 60 - 80 mm.
Note:
If the sweeping pattern is irregular in shape, arrange for Customer Service to
make the necessary corrections.

Operating cycle
Under favourable conditions, the sweeper has an
operating cycle of 10 hours with a full fuel tank at
the start. The actual time is dependent upon several
factors:
– surface structure of the ground and how level it is
– how well the sweeper has been maintained
– type of brush roller and its degree of wear.
