2Safety
2.1 General
•No modifications must be made to the weed brush.
•The user is responsible for making sure that the correct tool carrier and
adapter are used (see chapter 3). The following are important points in this
regard:
•The maximum pressure and number of revolutions (oil flow) must not be
exceeded. Excess pressure and excess revving can damage the machine and
cause injury.
•The tool carrier must be strong and stable enough to absorb the forces and
moments exerted by the weed brush safely and under all circumstances.
2.2 In use
•Consult the tool carrier manual for the noise rating. Because this is
considerably louder than the weed brush itself, the noise load of the tool
carrier determines the rating.
•The machinery must only be used for the activities for which it is designed.
•Persons or animals who are present in or who approach the danger zone must
be stopped immediately and the weed brush must be switched off .
•If passers-by disrupt the brushing and cutting work too much, the operator
can consider temporarily cordoning off the site.
•If the weed brush starts to make a different sound and/or starts to vibrate,
work must stop immediately and the weed brush has to be switched off. Work
can only continue after the source of the noise has been identified and
resolved.
•Always complete inspection and maintenance jobs.
•The machinery must not be used for any other purposes during inspection and
maintenance.
•The hydraulic feed to the weed brush must be disconnected during inspection,
maintenance or cleaning to prevent accidental operation.
•Always comply with local work regulations and safety rules.
•If the machinery is used in the dark, use sufficient lighting (approx. 50 lux at
the work site).
•To prevent damage to the machine, switching on and off the machine should
be done at low speeds. Depending on the tool carrier this is done at idle speed
or minimal oil-flow.

2.3 Operating personnel
•Operating personnel must be over 18.
•Only persons who have received permission from the owner are allowed to
operate the system.
•Persons must only carry out jobs for which they are trained. This applies to
both maintenance work and normal operations.
•Personnel who operate equipment must be familiar with all possible
situations that could arise.
•The owner or person in charge must be told if personnel operating machinery
identify faults or hazards or do not agree with safety measures.

pavement so it cuts the grass which grows over the
pavement.
2
Brush
•The brush brushes the weed and cut loose grass entirely from
the pavement.

Tool carrier
•The tool carrier is not supplied. The user is responsible for
using a tool carrier that is suitable for the weed brush.

Tool carrier
attachment
•The unit is attached by an adapter (figure 2:2) attached to the
tool-attachment-point (figure 2:1) of the tool carrier.
•The attachment off the weed brush to the adapter consists of
2 mounting-pins (figure 2:5) and 2 locking pins (figure 2:3)
•When the unit is in the right position it can be locked with the
lever (figure 2:4).
•The implementation of the adapter and its attachment to the
tool carrier is dependent on the type of tool carrier.
•The up and down movement is realized by the fixture to be
tool carrier. This is not part of the weed brush, it’s controlled
by the tool carrier.
6
Support legs
•Two support legs are attached to the weed brush (figure 2.6)
•The support legs have to be completely raised or removed.
•If the unit is dismounted from the tool the support legs can be
installed to put the unit down and stable on the ground.

1
Select the correct tool
carrier and lifting arm
•make sure that the tool carrier and lifting
arm are sufficiently strong and stable for
the weed brush (see chapter 1 for the load
when lifting and the exerted moment of
the lifting).
•Make sure that the maximum pressure and
number of revolutions (oil flow) are not
exceeded.
•Make sure that the correct rapid
attachment connections are installed for
the feed line, return line and drain line.
•Make sure that the correct clasp is used.
Ignoring the stated
values can result in
damage to
equipment and
injury to persons.
2
Connect the hoses
•Connect the rapid attachment connections
for the feed line, return line and drain line .
3
Adjust the hydraulic
system
•Adjust the setting of the hydraulic
aggregate so that the maximum pressure
and number of revolutions cannot be
exceeded.
•This will depend on the type of tool carrier
that is used. Please refer to the manual of
the tool carrier.
4
Adjust the positions
for the blade and
brush
•With help of the different hydraulic
functions the blade and brush can be
adjusted to achieve the correct result with
the weed brush.

4.2 Carry out brush- and cutting work
•At driveways or other obstacles in the cutting-lane the blade needs to be lifted
in time, to prevent damage to the pavement and machine
No.
What to do
Action
Result
1
Check the machinery
•Check the following points:
•Check the blade on cracks or damages
•Check the speed of the brush-motor
(50% of the capacity (30 liter)) is usually
enough for a good result
•Check whether the brush-motor runs
without excessive shaking and without
abnormal sounds.
•Check the control of the width and
height-adjustment of the blade.
•If a defect is identified in one of the above
points, this must first be remedied before it
is allowed to put the weed brush back into
operation.
2
Drive to the site
where the work will
take place.
•Always switch off the weed brush if you are
not doing any brushing.
3
Switch on brush-
motor
•Please refer to the detailed instructions in
the manual for the tool carrier.
•It is important always to switch on and off
at a low revolution speed to prevent
damage to the machinery. The revolution
speed can be increased after switching on
the brush-engine.
Switching on and off
at a high speed of
revolutions will
result in system
overload.
4
Setup the blade in
desired position
•The knife can be adjusted in width-position
and in height, make sure it is in desired
position. For detailed instruction, see
manual of tool carrier.
•Watch for people or animals in near
working area.
5
Cut and brush the
edges
•Drive the tool carrier along the edge of the
pavement.

Stop in following
situations!!
•The operator must stop immediately in
the following situations and switch off the
weed brush:
•Persons or animals being or coming
directly into the working area.
•The weed brush begins making
abnormal sounds or excessive shaking
Serious injury could
result if the
machinery is not
stopped in time.

Switch off the weed
brush
•switch off the weed brush once the area to
be cleaned had been brushed and cut.
Please refer to the detailed instructions in
the manual for the tool carrier.
•It is important always to switch on and off
at a low revolution speed to prevent
damage to the machinery.
Switching on and off
at a high speed of
revolutions will
result in system
overload.
