DESCRIPTION
The HANDY is a lightweight hand-held, spinning disc, Controlled Droplet Application (CDA) sprayer, designed for the application of herbicides at low volumes (10 to
30 litres/hectare). It is powered by four torch (D-cell/R20) batteries, which give over
40 hours spraying. Liquid is fed by gravity through colour coded feed nozzles. An
electrically governed motor spins the atomiser disc at a constant 2000 rpm to produce
uniform spray droplets of around 250 micron; large enough to minimise any risk of
spray drift. The ergonomic design of the HANDY, with the carrying handle and bottle being an integral part of the machine allows for closed chemical transfer and improved operator safety. The weight of the machine ready to spray is 6.2 kg.

SAFETY
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’).
Never use the HANDY in potentially explosive atmospheres or spray flammable liquid through it.
The HANDY can be used with most conventional herbicides, as well as specific
CDA formulations (only available in some countries).
Always read the product label carefully to discover:♦
♦
♦
♦
♦
approved applications
maximum dose rates
maximum number of treatments
operator protection required
necessary environmental protection measures
N.B. ‘Dose rate’ refers to the amount of chemical
product applied per hectare.
Never eat, drink, or smoke when working with agrochemicals. After using agrochemicals or handling equipment wash your hands thoroughly. Keep people
(especially children) and animals out of areas being sprayed.
Always store agrochemicals safely to protect people and animals, and to safeguard
the environment (take special care to avoid water pollution). See ‘SPRAYING’ sections for guidelines on safe use of the HANDY in operation.
OPERATOR PROTECTION
Always wear the protective clothing items listed on the product label for mixing and
filling. The minimum protective clothing required for spraying with the HANDY is:
♦
♦
♦
♦
rubber gloves
boots/shoes and long trousers
eye protection
long sleeved shirt
Note:
a) Acoustic information: the sound pressure level at the operator’s ear does not exceed
70 dB(A).
b) Vibration: the weighted RMS acceleration value at the hands when using this machine does not exceed 2.5 m/sec².

MIXING, FILLING AND CALIBRATION
Mixing and filling is generally the most hazardous process in the spraying operation.
Always follow the label instructions. Always use a funnel (preferably with a filter)
when filling the bottle. Only mix enough spray for the area to be treated thereby
avoiding the need for disposal of unused spray mix.
Always wear gloves when handling
agrochemicals and equipment.
Always use the correct equipment
when mixing and measuring.
Always clean all equipment after
use.
Always wash off any skin
contamination
With the HANDY herbicides are usually applied in around 20 litres total spray volume per hectare, with the exception of 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. Use the minimum dose rate recommended on the label for the intended treatment and add water to make up to the volume required for application with the HANDY.
6
For example, if the label recommends applying a minimum of 2 litres of product
made up to 200 litres of water per hectare with a knapsack sprayer, use 2 litres of
product made up to 20 litres for application with the HANDY, i.e. a spray mix concentration of 10%.
Do not use herbicide concentrations greater than the maximum recommended on the
label (unless specific training or recommendations have been given) if the label:
♦
specifically prohibits use of ‘Reduced Volumes’ i.e. increased concentrations;
♦
has a statutory 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
♦
carries one of the following hazard ratings: ‘very toxic’, ‘toxic’ or ‘corrosive’ or
carries the warning ‘risk of serious damage to the eyes’
Micron do not generally recommend using spray mixes 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 select the dose rate of product to be applied per hectare
(from the product label) and mix in a suitable container. With liquid formulations,
mixing can generally be carried out in the 5 litre spray bottle as shown below. Formulations which are harder to mix such as wettable powders or granules should be
first mixed in a bucket and the spray mix then transferred to the spray bottle.
1. Half fill the spray bottle with water
2. Measure out the exact amount of
product and add to the spray bottle
7
3. Fill with water up to the 5 litre mark.
4. Attach the spray bottle to the battery
case clamp, making sure that the union nut is firmly tightened.
5. Shake the bottle to ensure thorough
mixing - check for leaks.
6. Wipe the bottle with a dry cloth.
Never use leaking equipment. Take care to avoid the spillage of spray mix.
Examples of mixing spray - for 1 hectare

b) 2,4-D (500 g/l)
+8 litres
add water:
10 litres
Total volume:
3 litres
+17 litres
20 litres
i.e. 1 part glyphosate : 4 parts water
i.e. 3 parts 2,4-D : 17 parts water
e.g. 1 litre of glyphosate + 4 litre of
water in 5 litre spray bottle
e.g. 750 ml of 2,4-D + 4.25 litres of
water in 5 litre spray bottle.

The formula below gives the relationship between swath width, flow rate, walking
speed and total spray volume:
Flow rate (ml/min) = 6 x total spray volume (l/ha) x walking speed (m/s) x band width (m)
The table below gives examples of feed nozzle selection and walking speed to
achieve desired total volume application rates.

These values have been measured using water only. Actual flow rates will depend on
the viscosity of the spray liquid used and the angle at which the operator holds the
sprayer. Before spraying, therefore, the HANDY should be calibrated by the operator
for the spray mix being used.
CALIBRATION
To calibrate the HANDY remove the atomiser disc (see ‘AFTER SPRAYING’) and
collect and measure the volume of spray liquid dispensed in one minute with the
sprayer held in the normal “head down” spraying position (see ‘TO START SPRAYING’). As the balance of the machine and hence angle at which it is held will vary as
the spray bottle empties, an average flow rate will be obtained if measured with the
bottle half full.
It may be necessary to fit a different feed
nozzle to obtain the desired flow rate. To
change the nozzle, pull off the feed tube and
remove the two screws which hold the nozzle
in position. Alternative nozzles are located in
slots in the battery case clamp. These are

Yellow
colour coded according to flow rate. Select
the colour needed and screw into place.
Increasing flow rate
Red
Once the flow rate for a particular feed nozzle has been determined, walking speed
should be adjusted to achieve the required spray volume.
Example: required spray volume rate = 20 l/ha Flow rate measured = 150 ml/min
Walking speed (m/s) =
Flow rate (ml/min)
6 x 1 x total spray volume (l/ha)
=
150
6 x 20
= 1.25
In general it is preferable to walk more slowly to achieve the required spray volume
than to use higher flow rates.

BEFORE SPRAYING
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.
Before spraying for the first time use soap and water only to familiarise yourself with
the sprayer and check the spray pattern produced. Put around a litre of water in the
spray bottle and add a few drops of liquid detergent such as household washing up
liquid. The detergent is important to reduce the surface tension in the liquid feed tube
and helps ensure an even flow.
TO START SPRAYING
To start spraying, first switch on the motor
and check that the atomiser disc is spinning
(never touch the disc when it is spinning).
Then, holding the spray bottle by the handle,
tilt it backwards into the “head down” spraying position so that the spray head is below
the level of the bottle. This allows spray liquid to flow onto the atomiser disc.
The battery case should be at an angle of
around 35° to the ground with the spray head
about 20 cm above the ground or top of the
weed canopy. Make sure that the spray head
is far enough behind you so as to avoid contaminating the back of the legs. Look behind
to ensure that the sprayer is not leaking
around the union nut and to confirm that
spray is being issued from the disc.
“Head Down” Position
Start walking at the required speed. Occasionally glance behind to ensure that spray is
being produced from the atomiser disc and
the feed nozzle is not blocked.
At the end of the row do not interrupt the
flow by turning the sprayer into the head up
position, but continue application on the next
row.
10
TO STOP SPRAYING
If there is any spray liquid left in the spray bottle,
keep the motor running and slowly tilt the sprayer
so that the head is above the level of the bottle and
when no more spray liquid is emitted from the atomiser disc, switch off the sprayer. Do not raise the
spray head above waist level with the disc still spinning as spray may continue to be emitted.
“Head Up” Position
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 essential to clean the sprayer and bottle
thoroughly using water and detergent after use.
Never 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
bottle, rinsed around, and then sprayed out onto
the treated area or an area of waste ground. The
sprayer and bottle should be wiped down externally using a cloth.
3. Periodically remove the atomiser disc with a pair of pliers and clean using a soft
brush. When refitting the atomiser disc ensure that the two small lugs on the inside of the disc hole align with the slot in the white shaft which attaches to the
motor.
11
After working with agrochemicals, or handling spraying equipment, always 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.
STORAGE
Before storing for long periods, make sure that the batteries are removed to prevent
leaking and that the sprayer is clean and dry. Both the sprayer and batteries should be
stored in a dry place away from direct sunlight.
