Dear reader,
This operating manual provides all information for safe
operation of the Weed Brush WD 70.
This machine has been designed and built in accordance with
the state of the art and recognised safety rules and regulations.
Nevertheless dangers for personnel or objects can occur,
because not all danger zones can be avoided if the functionality
is to remain intact. However you can prevent accidents due to
these dangers by complying with the instructions in this
operating manual. Moreover you will then be able to use this
weed brush to its full capacity and avoid unnecessary
disturbances.
CAUTION!
There is danger of injury and danger of material damage when
assembling, operating, and maintaining the weed brush.
Therefore:
•First read this operating manual carefully, prior to assembly
and operation of the weed brush. Always comply with the
instructions and information contained herein, particularly the
safety instructions.
• If the operating manual is lost or in poor condition, request a
new copy from the manufacturer (the same applies for parts
of the operating manual).
This operating manual only applies for the machine specified on
the cover sheet and at the end of every page. Compare this
information with the information on the rating plate of the weed
brush.
After you have read the entire operating manual thoroughly for
the first time, take good care of the operating manual over the
entire service life of the weed brush, so that you can look up
something later.
If you sell the weed brush, give this operating manual to the
new owner.

The basic prerequisite for safe and trouble-free operation of the
weed brush is knowledge of the safety instructions and safety
regulations.
Consequently read this section carefully all the way through
before operating the weed brush, and comply with the specified
instructions and warnings. The safety instructions and warnings
that you find at the appropriate point in the text of the following
sections must be complied with. The manufacturer cannot be
made liable if the instructions and warnings are not complied
with.
In addition to the instructions contained in this operating
manual, the statutory regulations, particularly the safety and
accident prevention regulations, must also be complied with.
1.1 Intended use
The Weed Brush WD 70 may only be used to clean paths and
surfaces that are paved with concrete, asphalt, paving stones or
slabs outside of closed rooms.
Intended use also includes compliance with all the instructions
in the operating manual.
DANGER!
If the weed brush is used for a use other than the use described
above, dangerous situations can occur for people or material
damage can occur.
Therefore:
•Only use the machine for its intended purpose.
•Always comply with all the instructions in this operating
manual.
•Particularly refrain from the uses of the weed brush listed in

•It is used with non-approved braided brushes
•it is used in enclosed spaces, e.g. halls, or barns,
•It is manoeuvred or transported with the combustion motor
switched on or with the brushes rotating
•it is operated in faulty condition or with safety-relevant
faults,
•it is used without the safety cladding elements that are
installed as standard equipment,
•unsuitable personnel are assigned to operate the weed
brush.
•It is made heavier to increase the braided brush pressure
1.3 Product observation
Notify us without delay if faults or problems occur when
operating your weed brush, or if accidents occur or nearly
occur.
Together with you we will find a solution to the problem and
allow the knowledge gained to flow into our subsequent work.
