Introduction
Dear reader,
This operating manual provides all information for safe
operation of the Weed Brush Turbo.
The Weed Brush Turbo 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 the machine 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 weed brush specified
on the cover sheet and at the end of every page. Compare this
information with the information on the type 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.
All information, illustrations and dimensions in this operating
manual are non-binding. No claims whatsoever can be derived
from this information, illustrations or dimensions.

requires the written permission of the manufacturer.
Conversion of, or changes to the weed brush are only permitted
with the manufacturer's written consent. Unauthorised
conversion voids any liability on the part of the manufacturer, as
well as the guarantee.

characteristics of the weed brush, the functionality or the safety
can be impaired. Consequently the use of other parts voids the
liability for the ensuing consequences.

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 machine, 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 Turbo must only be used to remove and set
down weed growth on paved, concrete, and/or asphalt surfaces
outside of enclosed spaces.
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
section 1.2. They are considered non-intended use.
Safety

Page 8 of 33 19/02/2015 Weed Brush Turbo
1.2 Non-intended use
Any use that deviates from that described in section 1.1, is
considered non-intended use.
For example, non-intended use of the weed brush occurs when
•it is used to clean unpaved surfaces e.g. gravel paths,
•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.

1.4 Requirements for personnel
Handling the weed brush is only permitted for persons,
•who are at least 16 years old,
•who are physically and mentally suited to do so,
•who have read and understood this operating manual, and
•from whom it is expected that they responsibly perform the
tasks assigned to them.
Commissioning, maintenance, repair and disposal of the weed
brush may only be executed in a specialist workshop or by
persons with appropriate technical training and experience.
1.5 Danger zone
The danger zone is the area in which the safety or the health of
persons is jeopardised. Consequently no one should be in this
area when the weed brush is in operation.
WARNING!
For persons in the danger zone there is danger of injury due to
rocks or other foreign objects, or parts of the brush that are
thrown upwards by the machine
Therefore:
•Only operate the weed brush if no one is in the danger zone.
