Introduction
Dear reader,
This operating manual provides all information for safe
operation of the Limpar 72 sweeping machine.
The Limpar 72 sweeping 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 the sweeping 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 sweeping machine.
Therefore:
•First read this operating manual carefully, prior to assembly
and operation of the sweeping machine. 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 sweeping machine
specified on the cover sheet and at the end of every page.
Compare this information with the information on the type plate
of the sweeping machine.
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 sweeping machine, so that you can look
up something later.
If you sell the sweeping machine, 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.

Reprinting or duplication of any type, including excerpts,
requires the written permission of the manufacturer.
Conversion of, or changes to the sweeping machine 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.
Only use original spare parts and accessories that are
approved by the manufacturer. Otherwise the design-specified
characteristics of the sweeping machine, the functionality or the
safety can be impaired. Consequently the use of other parts
voids the liability for the ensuing consequences.
Contact your specialist dealer to order spare parts or
accessories.
In addition comply with the instructions in the operating manual
of the motor manufacturer. This is included in the sub-package
for the sweeping machine.

1 Safety
The basic prerequisite for safe and trouble-free operation of the
sweeping machine is knowledge of the safety instructions and
safety regulations.
Consequently read this chapter carefully all the way through
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 chapters 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 Limpar 72 sweeping machine 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 sweeping machine 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 sweeping machine for its intended purpose.
•Always comply with all the instructions in this operating manual.
•
Particularly refrain from the uses of the sweeping machine
listed in section 1.2. They are considered non-intended use.
Safety

Page 8of 39 05/19/2010 Limpar 72
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 sweeping machine
occurs when
•it is used to clean unpaved surfaces e. g. gravel paths,
•it is used to clean roofs or flat roofs,
•it is used in enclosed spaces, e.g. halls, or barns,
•it is used to transport persons or objects,
•it is used to move or carry objects or vehicles,
•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 sweeping
machine.
1.3 Product observation
Notify us without delay if faults or problems occur when
operating your sweeping machine, 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.
Safety

Limpar 72 19.5.2010 Page 9of 39
1.4 Requirements imposed on the operator
or personnel
Handling the sweeping machine 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
sweeping machine may only be executed by the specialist
dealer 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 sweeping machine is in operation.
WARNING!
For persons in the danger zone there is danger of injury due to
collision with the sweeping machine and due to thrown up
sweepings.
Therefore:
•Only operate the sweeping machine if no one is in the danger
zone.
•Carefully observe the danger zone and stop the sweeping
machine if persons enter the danger zone.
The danger zone is shown in the sketch (see Fig. 1, on the next
page):
A top view of the sweeping machine is shown. The shaded area
is the danger zone.
The danger zone on the right side and left side is determined
through the width of the sweeping brush. Toward the front side
of the sweeping machine the length of the danger zone is 5 m
in front of the sweeping brush.

direction also applies for the danger zone.
