DESCRIPTION
The HERBI-4 is a simple robust hand-held spinning disc Controlled Droplet
Application (CDA) sprayer powered by 6 volt 3 Ah LSA battery, with one set of good
quality battery giving over 20 hours spraying time. It is designed to apply herbicides in
a 1.2m wide band at low volumes (10 to 30 litres/hectare). A governed electric motor
spins the atomiser disc at a constant 2,000 rpm to produce uniform spray droplets of
around 250 micron; large enough to minimise any risk of spray drift. Liquid is fed by
gravity through colour coded feed nozzles. The HERBI-4 can apply herbicides to
borders, pathways, ditches and larger areas by making a series of consecutive spray
passes. The weight of the machine ready to spray, with the ST 10 litre backpack.

Specially designed ST backpacks and a shoulder strap are available for use with the
HERBI-4.
Using agrochemicals is a hazardous process. Operators should comply with all
relevant legislation and/or regulations governing the use of agrochemicals and should
use appropriate personal protective equipment (see ‘OPERATOR PROTECTION’).
use the HERBI-4 in potentially explosive atmospheres or spray flammable
liquid through it.
The HERBI-4 can be used with most conventional herbicides, as well as specific CDA
formulations (only available in some countries) to provide a closed transfer system to
improve operator safety.

MIXING, FILLINGAND CALIBRATION
Mixing and filling is generally the most hazardous process in the spraying operation.
follow the label instructions. use a filter (fitted in the )
and use a funnel if filling a container with a small neck. mix enough spray for the
area to be treated thereby avoiding the need for disposal of unused spray mix.
wash off any skin
contamination.
With the HERBI-4 herbicides are usually applied in around 20 litres total spray
volume per hectare, except for glyphosate which can be applied at volumes as low as
10 litres per hectare. These are lower volumes than recommended for high volume
application with knapsack sprayers.

Do not
Never
use herbicide concentrations greater than the maximum recommended on the
label (unless specific training or recommendations have been given) if the label:
a) specifically prohibits use of ‘Reduced Volumes’i.e. increased concentrations;
b) has a requirement for use of personal protective equipment when using the
diluted product at high volumes (N.B. this will appear in the statutory box on the
label);
or
c) carries one of the following hazard ratings: ‘very toxic’, ‘toxic’ or ‘corrosive’ or
carries the warning ‘risk of serious damage to the eyes’ e.g. paraquat (Gramoxone)
which is classified as toxic should not therefore be used through the HERBI-4 at
concentrations greater than recommended on the label. Micron do not generally
recommend using spray mixes of more than ten times the maximum concentration
recommended for high volume application with knapsack sprayers. The safest
product and lowest dose rate appropriate for the treatment should be used at all
times.
To prepare the spray mix first read the product label to determine the quantity of
product to be applied per hectare e.g. 2 litres of glyphosate per hectare. Then determine
the total spray volume to be applied per hectare with the Herbi-4 i.e. 10 or 20 litres per
hectare. Calculate the ratio of product in water e.g. 2 litres glyphosate + 8 litres water =
10 litre mix = 1: 4. Use this ratio to prepare the correct dose for the spray tank or bottle
e.g. with a 5 litre backpack mix 1 litre glyphosate with 4 litre of water.

The table below indicates the relationship between total spray volume, flow rate
and walking speed for the HERBI-4 as per the following formula:
Flow rate (ml/min)=6xtotal spray volume (l/ha) x walking speed (m/s) x band width (m)
Note: The flow rates in this table were measured with the spray head 65cm below the level of the liquid in the
tank, using water only. The flow rate will vary with differences in this height and the viscosity of the spray
mix (for very viscous spray mixes it may be necessary to use a larger feed nozzle).
CALIBRATION
not
Choose and fit the feed nozzle that is likely to be required. The actual flow rate should
be checked holding the HERBI-4 in the spraying position. Remove the feed nozzle
from the spray head by and pulling out, then, once liquid has reached the feed
nozzle, allow the liquid to flow into a suitable container for one minute and measure
the volume dispensed. If the flow rate is in the recommended flow rate range of 60
to 150 ml/min change the feed nozzle and repeat the above procedure.
N.B. It is preferable to walk more slowly to achieve the required spray volume than to
use higher flow rates.

BEFORE SPRAYING
Always
TO START SPRAYING
Do not
Check the wind speed and direction (below 5 kph) is safest. Take special care to avoid
drift by keeping the spray head as low as possible. spray into the wind and avoid
walking into the spray. keep the spray head at least 60cm from any part of the
body to avoid direct contamination by the spray.
Before spraying for the first time use water to check the spray pattern produced.
Put some clean water in the tank and add a small amount of detergent. Check for leaks.
Switch on the sprayer and then open the flow valve. Spray on one spot, preferably on
clean dry concrete, for around 30 seconds with the spray head held about 20cm above
the ground; a wet ring 1.2m wide should appear on the ground. Practice using the
sprayer by walking along a few metres and then stopping spraying (see ‘TO STOP
SPRAYING’).
Hold the spray head about 20cm above the ground or weed foliage. Switch on the
sprayer, check the atomiser disc starts spinning ( touch the atomiser disc when
spinning or hold the spray head too close to the operator) and then open the flow valve.
Start walking immediately the spray liquid reaches the feed nozzle. N.B. with the
HERBI-4 Extra both flow valves must be opened.
The HERBI-4 is normally held at an angle of around 35° to 40° to the ground with the
head inclined slightly away from the operator. spray with the HERBI-4 held on
the shoulder, since spray may contaminate the operator. N.B. the machine will not
spray with the spray head above the level of liquid in the tank.
Never
only
never

It is best to hold the HERBI-4 to the side or the rear so that the operator does not have to
walk over the treated area.
Close the flow valve and switch off the sprayer. When the atomiser disc has
stopped spinning raise the sprayer to an angle of 45°(see below). raise the spray
head until the atomiser disc has stopped spinning. open the flow valve and drain
any remaining liquid in the feed tube back into the tank (by raising the feed tube above
the level of liquid in the tank). Then close the flow valve.
For ease of transport the tank can be disconnected (use the flow valve to isolate any
liquid left in a backpack) and the sprayer collapsed (OFF the switch and disconnect the
3 pole connector).

AFTER SPRAYING
1. Dispose of any surplus spray mix according to the product approval. Store products
safely, locked up and out of the reach of children.
2. It is to clean the sprayer and tank thoroughly using water and detergent
after use. immerse the spray head in water or under a tap, since this will
destroy the electric motor. A water and detergent mix should be put in the tank,
swilled around, and then sprayed out onto the treated area of waste ground. The
sprayer and tank should be wiped down externally using a cloth. Periodically
remove the atomiser disc with a pair of pliers and clean with a soft brush.

3. After working with agrochemicals, or handling spraying equipment,
thoroughly wash hands and exposed skin. All protective clothing should be washed
separately from other clothing and stored. Contaminated gloves should be washed
inside and out.
Before storing the HERBI-4, clean all the electrical contacts with wire brush or
similar. The machine should be stored in a dry cool place.

A) Atomiser disc spins but does not spray or sprays irregularly. Check:
- The feed nozzle. If the feed nozzle is blocked remove and soak in soapy water.
blow through the nozzle with your mouth. Check that the feed nozzle
gives a flow rate within the operating range.
- The atomiser is clean and undamaged. Clean or replace.
- The flow valve for blockage. Rinse through with soapy water.
B) Atomiser disc fails to spin or spins unevenly. Check:
- Charging was done correctly.
Switch should be in ON position when charging, 3 pole connector is connected
properly.
- The condition of the batteries. Replace if necessary.
- That electrical terminals and contact points are clean and that electrical wires are
not broken or corroded.
- If the atomiser disc is rubbing on the motor base plate or the motor shaft is bent.
Replace the disc or motor if necessary.
- The motor for corrosion or obvious signs of wear. Replace if necessary.
N.B. Battery condition can be checked with a torch (or a torch lightbulb and electrical
wire).
