Safety in operation of the supplied unit can only be guaranteed if it is used
appropriately and correctly. Appropriate use includes following the operating
and instruction manual (also of the tractor) and carrying out all the maintenance
and servicing work. Attachments and equipment from other manufacturers may
only be used after consulting BRAUN Maschinenbau GmbH.
This unit has been designed solely for the usual soil tilling in vineyards and
orchards or in specialised cultivation.
Any form of use going beyond this is not appropriate!
BRAUN Maschinenbau GmbH shall have no liability whatsoever for any
damage caused as a result, the user/owner bears the sole risk in such cases.

regulations and other generally recognised safety, occupational medicine and
road traffic rules are to be complied with.
3.7 Traffic safety
When travelling on public roads and streets the tractor must comply with the
road traffic regulations of the relevant country when this unit is attached to it.
The vehicle holder and tractor driver are responsible for compliance with these
regulations.
3.8 Danger zone when in operation
Never allow anybody to get into or stay in the danger zone!
If you get between the tractor and the unit there is a great and possibly fatal
danger from the tractor rolling away or from movements of the unit.
The following illustration shows the danger zones of the unit.

4.1 Installation
4.1.1 Installation description LUV
WARNING
The LUV can fall over
Your lower limbs could be crushed
Wear safety shoes
Handle heavy loads with lifting gear
Component
Installation steps

2. Push the LUV so that it is flush with the front
edge of the square
3. Insert the bolt (1)
4. Adjust and lock the adjusting bolts (2)
5. Firmly tighten up the bolt (1)
CAUTION
Slipping of the hydraulic couplings
Minor hand injuries
Wear safety shoes
Careful handling
Component
Assembly steps

4.2 Setting up/adjusting
4.1.2 Feeler positions
Component
Adjustment steps
1. Align the feeler so that it is parallel
to the ground (red marking)
Ensure a 90° angle!
2. When operating the feeler up to the
détente stop of the control valve
this must be flush with the front
edge of the crow's foot blade
NOTE
Depending on the requirements, the feeler can be set to be minimally in front of the blade to create a
buffer zone
Component
Adjustment steps
1. Feeler position [1]
Vines growing straight
Push the feeler, without turning the toothed
wheels,
(in the hole of the toothed disk pair) further to
the front (with respect to the plant) to create a
buffer zone
2. Feeler position [1`]
Steep slopes
Turn the feeler at the feeler hoop to the front (to
the right, counterclockwise, to the left,
clockwise) by means of the fine teeth of the
toothed disk pair to increase the distance
B`between blade and sensor
3. Travelling speed [B]
Reaction time
Push the feeler further into the bolt holder to
swivel more quickly under the row of vines
NOTE
Feeler position [1]
The feeling setting with parameters A and B is intended for vineyards / orchards on flat terrain.
Distance A with respect to A´. is increased. This buffer zone represents an additional protective
element for the plants. The LUV unit can be initiated earlier by earlier and longer contact between
feeler and plant. The result is that the weeding area around the plants is reduced and the safety
clearance is increased.
Feeler position [1`]
For steep slopes or problem areas (with plants that grow irregularly or not straight) the feeler at the
feeler hoop can be turned to the front (to the right, counter clockwise, to the left, clockwise) by means
of the fine teeth of the toothed disk pair. The distance B` between blade and feeler is increased as a
result so that the blade swivels inwards earlier before the vine with the aid of the feeler.
Travelling speed
The higher the speed of the tractor, the further the feeler must be pushed into the bolt holder
(reduction of distance A) so as to swivel more quickly to back under the row of vines after initiating.
In the same way, when travelling slowly, the feeler must be pushed more out of the bolt holder
(increase of distance A A´) so that the blade does not swivel into the row of vibes too quickly.

4.1.3 Crow's foot blade
Component
Adjustment steps
1. Rotate the crow's foot blade itself by 25° (2 teeth) to the
rear (away from the plant)
(The illustration shows the working position)
NOTE
The feeler of the LUV Perfekt with crow's foot blade is built in a similar way to that of a conventional
crow's foot blade. The earth that had been heaped up between the vines can be ploughed out with the
crow's foot blade.
4.2 Storage and protection between periods of use
Store the unit so that it is cool and dry. Protect it against the direct rays of the sun.
Clean and lubricate the unit if it is to be stored for a longer period of time.
4.3 Storage location for the operating manual
The operating manual must be readily available to hand for the user at all times.

18
5 Operation
5.1 Safe operation / functioning
Do not operate the unit without a vehicle (tractor). Follow the operating manual of the
relevant tractor.
DANGER
Running over persons
Death or severe injury
Never allow anybody to get into or stay in the danger zone
Ensure that nobody is in the danger zone of the unit (see section 3.8).
If any persons get into the danger zone of the unit, stop the tractor at once.
5.2 Work flows
NOTE
Resistance of the soil is too great
Blade or other component can break
Only let the blade into the ground while in motion
The LUV may only be lowered into the ground in the row while in motion.
Next, turn on the oil supply of the LUV.
5.3 Operating information
5.3.1 Oil
The LUV unit and all the hydraulic components are not suitable for use with bio-oil!
5.3.2 Soil
The LUV unit can be used in all the usual types of soil, but less good working results
can be expected in very stony soil, unless it is pre-treated. Here we recommend that
the soil should be prepared beforehand with a suitable device. Around 5-10 cm
should always be ploughed up to achieve the best results. It is easier to distinguish
weeds as a result and there is less formation of islands of grass.
