operating instructions.
– This sweeper has been designed to
sweep dirt and debris from indoor as
well as outdoor surfaces.
– This device is suitable for commercial
use in hotels, schools, hospitals, facto-
ries, shops, offices, and rental compa-
nies.
– The machine with working equipment
must be checked to ensure that it is in
proper working order and is operating
safely prior to use. Otherwise, the appli-
ance must not be used.
– The machine is not suitable for vacuum-
ing dust which endangers health.
– The machine may not be modified.
– The machine is only suitable for use on
the types of surfaces specified in the
operating instructions.
– The machine may only be operated on
the surfaces approved by the company
or its authorised representatives.
– The following applies in general: Keep
highly-flammable substances away
from the appliance (danger of explo-
sion/fire).
– Never vacuum up explosive liquids,
combustible gases or undiluted acids
and solvents. This includes petrol, paint
thinner or heating oil which can gener-
ate explosive fumes or mixtures upon
contact with the suction air. Acetone,
undiluted acids and solvents must also
be avoided as they can harm the mate-
rials on the machine.
– Never sweep/vacuum up reactive metal
dusts (e.g. aluminium, magnesium,
zinc), as they form explosive gases
when they come in contact with highly
alkaline or acidic detergents.
– Do not sweep/vacuum up any burning
or glowing objects.
– The machine may not be used or stored
in hazardous areas. It is not allowed to
use the appliance in hazardous loca-
tions.
– Asphalt
– Industrial floor
– Screed
– Concrete
– Paving stones
The sweeper operates using the overthrow
principle.
– The side brushes (1) clean the corners
and edges of the surface and move dirt
and debris into the path of the roller
brush.
– The rotating roller brush (2) moves the
dirt and debris directly into the waste
container (3).
– The dust raised in the container is sep-
arated by the dust filter (4) and the fil-
tered clean air is drawn off by the suc-
tion fan (5).
Your sales outlet should be informed about
any transit damage noted when unpacking
the product.
– Read and adhere to the operating in-
structions and safety notes of the at-
tachments affixed to the appliance.
– Warning and information plates on the

Danger
Long hours of using the appliance can
cause circulation problems in the hands on
account of vibrations.
It is not possible to specify a generally valid
operation time, since this depends on sev-
eral factors:
– Proneness to blood circulation deficien-
cies (cold, numb fingers).
– Low ambient temperature. Wear warm
gloves to protect hands.
– A firm grip impedes blood circulation.
– Continuous operation is worse than an
operation interrupted by pauses.
In case of regular, long-term operation of
the device and in case of repeated occur-
rence of the symptoms (e.g. cold, numb fin-
gers) please consult a physician.
Release parking brake.
Start the motor.
Turn the main switch to position “1”.
Note: The roller brush and the side brush
will rotate.
Pull the lever for forward drive.
Note: The drive speed for forward drive
can be adjusted steplessly depending on
the position of the lever.
Release the lever for forward drive. De-
vice comes to a halt.
Driving over fixed obstacles which are 30
mm high or less:
Raise bulk waste flap.
Drive forwards slowly and carefully.
Driving over fixed obstacles which are
more than 30 mm high:
Only drive over these obstacles using a
suitable ramp.
�
Danger
Risk of injury! If the bulk waste flap is open,
stones or gravel may be flung forwards by
the roller brush. Make sure that this does
not endanger persons, animals or objects.
CAUTION
Do not sweep up packing strips, wire or
similar objects as this may damage the
sweeping mechanism.
Note: To achieve an optimum cleaning re-
sult, the driving speed should be adjusted
to take specific situations into account.
Note: To sweep up larger items up to a
height of 50 mm, e.g. cigarette packs, the
bulk waste flap must be raised briefly.
Raising bulk waste flap:
Pull the lever for raising the bulk waste
flap.
Lowering the bulk waste flap:
Release the lever for raising the bulk
waste flap.
Note: An optimum cleaning result can only
be achieved if the bulk waste flap has been
lowered completely.
Move the lever to lower the side brush
to the front. The side brush will be low-
ered.
Note: During operation, the waste contain-
er should be emptied at regular intervals.
Note: During operation, the dust filter
should be shaken off and cleaned at regu-
lar intervals.
Close wet/dry flap
Open wet/dry flap.
Note: This protects the filter from moisture.
