OPERATING INSTRUCTIONS
MANTRA
ULV- Applicator for weed control
in areas of specialised cultivation such as nurseries, orchards and
vineyards, ornamental plant and vegetable gardens, as well as
agricultural, forestry, communal and non-cultivated lands.
The unit has been developed for the undiluted
application of ROUNDUP products (Glyphosate).
Important:
Before application, carefully read the usage instructions for the unit and the plant protective agent!
Observe safety instructions!
For questions regarding plant protective agents, consult the manufacturer!
Observe the requirements and regional regulations for the use of herbicides and, if necessary,
obtain approval from the responsible authorities (e.g. environmental conservation agency)!
Application is to be performed only by a competent user.
Remarks about usage of the unit:
Settings: This system is not suitable for the application of water.
Use herbicides for testing the spray action and calibration of the flow rate.
Usage: Position the spray hood directly above the ground –
if the spray hood is held too high, the danger of spray driftage exists.
Cleaning: Do not clean the unit with a high-pressure spray or an intense water jet spray.
Storage: Store the unit at an angle of between ca. 45°(= work position) and 0°(= horizontal) to the
floor (see picture).
Keep the applicator and pesticides out of the reach of children.
Noise emission from the unit equates to less than 70 dB(A).

MANTRA
For the undiluted application of Roundup®products (Glyphosate)
Intended usage:
Weed control in areas of specialised cultivation such as nurseries, orchards and vineyards, ornamental plant and
vegetable gardens, as well as agricultural, forestry, communal and non-cultivated lands.
Before application, carefully read the usage instructions for the applicator and pesticides.
Observe safety instructions.
For questions regarding pesticides, consult the manufacturer!
Observe the requirements and regional regulations for the use of herbicides. Permission is required from the
responsible authorities (e.g. environmental conservation agency) for the application of herbicides on surfaces
used for non-agricultural, forestry or gardening purposes („ non-cultivated lands“ ). No application is permitted on
sealed surfaces (e.g. pavement surfaces) connected to the sewage water system, from which the danger of run-off
exists!
Application is to be performed only by a competent user.
Noise emission from the unit equates to less than 70 dB (A).
Protective measures
Observe remarks in the usage instructions for the
pesticide regarding the safety of the user; wear
recommended body protection. Wear protective gloves
when filling the chemical.
Do not eat, smoke or drink while working with
pesticides.
Avoid chemical spillage without fail. After completion of the
work, thoroughly clean hands and face.
Thoroughly clean and dry the unit immediately following its
usage. Never use the mouth to blow out nozzles or other
small parts!
Keep pesticides and applicators away from children.
Assembly and preparation for the first application
Assembly of this unit is described on page 2.
Before the first application of the unit, allow the battery to charge for at least 16 hours. First plug the applicator plug into the
loading socket, then plug the charging device into the 230 V power outlet. After ca. 16 hours charging time, the battery has
reached its full voltage capacity. When the charging process is complete, first unplug the charging device from the 230 V
power outlet, then unplug the unit plug from the charger socket.
The spray width should be subsequently checked - ideally with a piece of cardboard laid out on the ground - and
the flow rate adjusted (see below for specifics).
General remarks about the function and regarding the first application of the unit
Pesticides: This applicator was originally designed for the undiluted application of Roundup products (Glyphosate).
Practical experience has shown, however, that other herbicides can also be deployed in conjunction with this technology.
Considering the many products on the market with their differing formulations, it is not possible to provide a complete list
with application rate recommendations. The specifications depicted below for adjusting the applicator relate to the usage of
Roundup UltraMax (Glyphosate 450 gr/ltr). In general, all products with a comparable viscosity are suitable. If you intend to
use a product other than Roundup UltraMax, its application should be initially tested on a trial basis over a small area. In
any case, the usage instructions for the chosen herbicide should be observed along with the local requirements.
Applicator function: The rotating atomiser is driven by means of a rechargeable battery. Metering takes place by means of
a metering valve. Droplets are formed by the centrifugal force of the rotating atomiser. The droplets are discharged
downwards by the rotating atomiser through a step-free, adjustable segment. The residual chemical in the tank, not able to
be applied, is approximately 10 ml. This residual fluid can be refilled back into the original herbicide container.
Checking applicator function: Chemicals can flow at differing rates, more quickly or slowly, due to temperature
variations. For this reason, the flow rate depicted in the metering table must be checked and corrected as
necessary. This technology is not suitable for the application of water. Always use herbicides for testing the spray
process and for calibrating the flow rate. Check the rotating atomiser for cleanliness and free turning movement
on a daily basis. Check the application volume from time to time throughout the season.
Deployment of the applicator: Position the spray hood directly above the ground - if the spray hood is held too
high, the danger of spray driftage exists. During operation, chemical fluid will collect in the atomiser reservoir and
will continue to drip for ca. 30 seconds after the stop valve is closed. For this reason, close the valve ca. 1 minute
before ending the work task, while the atomiser continues running; then switch the atomiser motor off.
Attention! Before lifting or tilting the spray hood, it is essential that the stop valve is closed and the atomiser motor is
switched off.

Cleaning
Do not clean the applicator with a high-pressure spray or with an intense water jet spray.
Cleaning during the season: During short breaks in the work day (a few hours), the herbicide can
remain in the system as long as the metering valve is closed. After completion of work task: before
cleaning, return the chemical into its original container. Set the metering valve to maximum (water
cock symbol). Fill the chemical tank half way with water, actuate the button switch and allow the
atomiser to run for 3 minutes over a collector tank or spread the cleaning fluid over the previously
worked surface. Remove the remaining water from the tank.
Cleaning after the season: Rinse the unit with warm water as described above. Additionally: open
filter and clean screen if necessary. The spray hood and the atomiser housing can be cleaned with
a moist cloth, except the atomiser disc in order to avoid damage. For heavy contamination, the
atomiser housing should be unscrewed to remove contaminants and plant parts. Connect the unit
to the battery charger (see below).
Charging the applicator and care of the accumulator
The applicator is fitted with an automatic charging device. Trickle charging is possible.
In order to charge a completely empty battery back up to full capacity, ca. 16 hours charging time is required. When a battery is
empty, it should be immediately recharged. Never leave a battery discharged for long periods.
Battery charging Minimum charging time Time interval
Fully discharged 16 hrs. immediately
Short-term usage 6 hrs. immediately
Storage without usage ( 2 hrs. 1 x per month) or permanent charge
The applicator can be used for ca. 16 hours with a fully charged battery.
