2. Safety
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 1). 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 (10m)
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.

Description
1
Width adjustment
•The position of the brush in the width direction can be set by
putting the mounting in a different positioning hole (Figure
4:1)
•The optimum position depends on the tool carrier and the
operator and is typically set only once.
2
Mud guard
•The protective mudguard (figure 4.2) makes sure the debris
from the brush don’t get thrown in the wrong direction.
•The right position can be achieved by different adjustment-
points.
3
Angle adjustment
brush
•The angle in which the brush brushes the pavement can be
adjusted by un mounting the connecting bolts (Figure 4:3).
4
Brush-mounting
•When the brush is worn out it can be easily replaced by
unbolting the mounting bolts from the holder-plate (figure
4:1).

No.
What to do
Action

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 1Fout! V
erwijzingsbron niet gevonden. 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 brushing- 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.

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.
7
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.

replacement or repair of parts.
•Always disconnect the weed brush from the feed line when work is carried out
on the machinery. This is done by disconnecting the rapid attachment.
•Only persons who can show that they have adequate knowledge of
mechanical and hydraulic machinery through their training and experience are
allowed to carry out maintenance work.
•The installation can be cleansed with a high pressure cleanser, never point
directly at hydraulic components.
