2Safety
2.1 General
•The weed brush may not be modified.
•It is the user’s responsibility to ensure that the correct tool holder is used (see
Section 1:Technical details). To this end, the following points are important:
•The maximum pressure and rotational speed (oil flow) must not be
exceeded. Exceeding these limits may damage the installation and injure
bystanders.
•The tool holder must be sufficiently strong and stable enough to bear the
forces and torques caused by the weed brush in all circumstances.
2.2 During use
•Consult the manual for the tool holder and the additionally attached options
to look up the resulting sound load. As the specified nominal RPMs is
significantly higher than the sound produced by the weed brush, the sound
load from the tool holder is leading.
•The installation may only be used for the work activities it is designed for.
•If people or animals approach or enter the safety zone, the weed brush and
the work activities must be stopped immediately.
•If passers by constantly interrupt the work activities too much, consideration
should be given to fencing off the work area.
•If the weed brush begins to make a different sound and/or starts to vibrate,
the work and the weed brush must be immediately stopped (see 4.2). The
work must not restart until the cause is found and resolved. .
•Inspection and maintenance work must be carried out.
•During inspection and maintenance, the installation must not be used for
other purposes.
•During inspection, maintenance, or cleaning, the hydraulic feed to the weed
brush must be disconnected to prevent it being accidentally switched on.
•The local work and safety regulations must be observed.
•If the installation is to be used in the dark, sufficient lighting must be used
(approx. 50 lux on the place of operation).
•To prevent damage to the installation, the device must be gradually switched
off using the lowest RPMs. Depending on the tool holder used, this is idling
speed or the minimal flow.
2.3 Operating personnel:
•Operating personnel must be older than 18 years of age.

•Only individuals authorized by the owner may work on or with the installation.
•Operators may only perform work activities that they are trained for. This
applies to both the maintenance work and normal usage.
•The operating personnel must be acquainted with all situations that can
occur.
•If the operating personnel discover faults or risks or do not agree with the
safety measures, this must be reported to the owner or person in charge.

What to do
Action
Result
1
Select the correct tool
holder.
•Ensure that the tool holder is sufficiently
strong and stable enough for the weed
brush (see Section 1:Technical details for
the unladen weight, the load in the nesting
place, and the resulting torque in the
nesting place).
•Ensure that the maximum pressure and
rotational speed (oil flow) cannot be
exceeded.
•Ensure the correct quick-release couplings
are attached for the supply, return, and
leak lines.
•Ensure that the correct adapter is
attached.
Not respecting the
specified limits may
damage the
installation and
injure bystanders.
2
Connect the hoses
•Connect the quick-release couplings for the
supply, return, and leak lines.
•See the tool holder manual for the correct
connection positions.
3
Adjust the oil supply.
•Adjust the generator for the tool holder so
that the maximum pressure and rotational
speed cannot be exceeded.
•This depends on the type of tool holder
used. See the tool holder manual.
4
Adjust the brush to
the desired position
•Various settings allow the brush to be
adjusted so that the optimal setting is
achieved for the tool holder and operator.

4.2 Using the weed brush
No.
What to do
Action
Result
1
Check the installation
•Check the following points:
•Check the rotational speed of the brush
motor. In practice, 50% of the capacity
(30 liters) is sufficient for decent results.
•Check that the brush motor runs without
vibration and there are no irregular
sounds.
•If one of the above checks discovers a
deficiency, it must first be rectified before
the weed brush can be used.
2
Drive to the work
area
•Always switch off the brush motor when it
is not being used.
3
Switch on the brush
motor
•For detailed instructions, see the tool
holder manual.
•To prevent damage to the installation, it is
important that the weed brush is gradually
switched on or off using the lowest RPMs.
Once the installation is switched on, the
RPMs can be increased.
Switching on or off
at high RPMs causes
high loads on the
installation.
4
Adjust the brush to
the desired position
•Use the width setting and the height
setting to achieve the correct brush
position. For detailed instructions, see the
tool holder manual.
•Check that no one is in the work area.
5
Brushing
•Drive with the tool holder over the street.
6
Stop in the following
situations!
•The weed brush and the work activities
must be stopped immediately in the
following situation:
•People or animals are present in the
work area. The driver must make this
assessment.
•The weed brush starts making a
different sound or starts to vibrate.
If you do not stop
promptly in the
above situations, it
may lead to serious
injury.

Switch off the weed
brush
•Once the work activities are complete,
switch off the weed brush. For detailed
instructions, see the tool holder manual.
•To prevent damage to the installation, it is
important that the weed brush is gradually
switched on or off using the lowest RPMs.
Once the installation is switched on, the
RPMs can be increased.
Switching on or off
at high RPMs causes
high loads on the
installation.

5Maintenance
•Components may only be replaced or repaired using components delivered by
or approved by the manufacturer.
•If work activities will be carried out on the installation, the weed brush must
always be disconnected from the power supply. You can do so using the quick-
release couplings.
•Only trained and/or experienced individuals who can demonstrate they have
sufficient knowledge of mechanical and hydraulic installations may perform
the maintenance work.
•The installation may be spray cleaned using a high-pressure jet cleaner.
However, never spray the hydraulic components.
Weekly maintenance
No.
What to do

1
Lubricate pivot points
•Spray grease in the grease nipples. These
are located:
•at all of the articulating points.
2

•Check the fastener bolts.
3
Visual inspection
•Visually inspect the structure and the
hydraulic installation for damage and
cracks.
4
Retighten adjusting
bolts

6Malfunction analysis
Malfunction
Solution
1
After switching on, the brush
motor does not rotate
•Check that the hydraulic hoses are connected.
2
The machine works, but has no
or insufficient brush force.
•Check that the motor rotation direction is correct. If this
is not the case, you can change it using the quick-release
coupling to switch the pressure and return hoses.
If you cannot resolve the malfunction using the recommendations in the above table, consult with
your dealer or maintenance department.
