The unit has been developed for t he 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 pr ot ec t ive agent s , c onsult t he m anufacturer!
Observe the requirements and reg ional 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 us er .

Remarks about usage of t he unit:

Settings: This system is not suitable for the application of water.

Use herbicides for testing the spr ay action and calibrat ion of the flow rate.

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 3.
Before the first application of the unit, allow the battery to charge for at least 8 hours. First plug the applicator plug into the
loading socket, then plug the charging device into the 230 V power outlet. After ca. 8 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. If the unit is switched on the battery monitoring LED lights green (fig. page 3/4)

Before using the MANKAR HQ the breather hole of the lid has to be opened.
If the air-vent is closed there won’t be an even chemical flow.
After usage the breather hole has to be closed to prevent leaking.

General remarks about the function and regarding the 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.
Because of the compatibility with the materials used never use aggressive, solvents containing cleaning agents or gasoline.

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 can continue to drip
for few seconds after pressing the switch- valve unit. Make sure that the valve of the bottle lit is open before use. After
usage close the valve again to provide leakage.

Attention!
If there is any leakage the stop working and repair the unit.

Before lifting or tilting the spray hood, it is essential that the stop valve is closed and the atomiser motor is switched off.
Cleaning: It is common practice that spraying systems need a minimum of service and maintenance same applies for the

MANKAR HQ. Rinse the unit with warm clear water. To accelerate the cleaning procedure a cleaning agent like “tank­cleaner” can be used. Regular cleaning reduces sediments and prevents obstructions of the valve and blocking of the
atomizer.

Setting and verification

Flow rate

• Place an underlay (e.g. cardboard or paper) on the ground.

• Fill the chemical tank with herbicide (undiluted).

• Set down the applicator as pictured below.

• Remove the hose from the atomizer. (B)

• Place the measuring cylinder beneath the flow rate controller (see drawing on page 3).

• First set metering valve to maximum. (D)

• Actuate switch/valve unit (C) and select continuous operation by pushing the button switch forward.

• When the herbicide reaches the metering valve (identifiable i n the flow rate controller), the desired setting

(see table) is adjusted on the valve. (D)

• Collect the herbicide for 60 sec. in the measuring cylinder.

• If desired quantity is not reached, readjust metering valve and calibrate again.

• Afterwards reattach the hose.

Example for the MANKAR HQ: The setting A is an approximation for Roundup UltraMax; 3 ml/min. Deviation from
the desired volume can be regulated at the metering valve by setting a greater or lesser flow rate.

Spray width

• Hold the applicator in its working position above the overlay (e.g. cardboard or paper). Actuate the button switch
and initially direct the spray hood at the underlay, appraising the spray width at various heights above the section
being sprayed. The spray width must be set in such a manner that the droplets are discharged over the entire
spray hood width. The optimal spray width is set by the manufacturer under standard operating conditions.

• It is possible to compensate for deviations by loosening the screw (F) and sliding the width adjustment on the
atomiser (see drawing) to adjust either side so that the spray jet just misses the edge of the hood.

Working width

• The whole spray hood of the MANKAR HQ can be turned continuously to get a working width from 45 to 15 cm.

When the desired volume is obtained, the spray width verified and the working width adjusted, the application
process can begin.

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 or cleaning agent like “tankcleaner” as
described above. 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 page 3).

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 8 hrs. immediately
Short-term usage 3 hrs. immediately
Storage without usage ( 2 hrs. 1 x per month) or permanent charge

The applicator can be used for ca. 8 hours with a fully charged battery.

Battery and motor monitoring

If the battery is fully charged the LED lights green. If the battery was
charged for 8 hours and the monitoring LED still lights red, the
atomiser disc might be seized. Reason for that can be insufficient
cleaning. (see fault remedy below)
Another reason might be a defective battery. In this case the battery
has to be replaced.
