DESCRIPTION
The AccuDos 2P is a spray applicator for the accurate dispensing and delivery of a
measured volume of spray liquid. The AccuDos 2P has the facility to ‘dial-in’ a pre
determined quantity of spray liquid from 0.1 - 2.0 ml per shot. A choice of spray nozzles, specifically selected to deliver the appropriate spray quality, are available to ensure that spray is transferred accurately to the target. An anti-drip check valve is fitted as standard. The AccuDos 2P is supplied with a purpose designed five litre Micropak backpack with a filter and large aperture to facilitate ease of cleaning and filling. Liquid flow can be shut off with an in line tap which allows for disconnection of
the backpack and hand lance.

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 AccuDos 2P in potentially explosive atmospheres or spray flammable
liquid through it.

Always store agrochemicals safely to protect people and animals, and to safeguard
the environment (take special care to avoid water pollution).
4
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.

1. First remove the hose pipe and flow
control valve stored inside the five
litre backpack. Connect the hose
pipe to the backpack and then connect the spray lance to the flow control valve according to the instructions contained inside the backpack.
2. Fit the straps onto the backpack at the anchor points indicated.
3. Half fill the reservoir with clean water. Turn the dial on the hand lance to read 2
4. Holding the spray lance vertical to
point upwards, open the flow control valve and then operate the trigger mechanism until all the air has
been expelled from the syringe
chamber and lance.
Expel all air
5. Spray onto a dry surface to determine if the spread and spray pattern of the nozzle
is suitable.

6. If necessary, select an alternative
nozzle by unscrewing the union nut
on the nozzle adapter and inserting a
different nozzle.

The choice of nozzle will depend on the spray target. In general the hollow cone nozzle fitted is suited to spot treatments of small areas or application of insecticides or
fungicides. Alternative flat fan nozzles are also available.

MIXING, FILLING AND CALIBRATION
SPRAYING
Mixing and filling is generally the most hazardous process in the spraying operation.
Always follow the label instructions. Only mix enough spray for the area to be
treated thereby avoiding the need for disposal of unused spray mix.
The AccuDos 2P can be used for application of spot treatments to individual weeds or
patches of weeds. It can also be used for treating circles around trees or fence posts.
Experience will indicate the optimum volume to be dispensed for any given
application.
The required quantity can be dialled in by
turning the knurled knob until the desired
volume is shown by the position of the
syringe in the graduated barrel. Turn the
knob anti-clockwise to increase volume
and clockwise to decrease volume.
Always use the correct equipment
when mixing and measuring.
Always wear gloves when handling
agrochemicals and equipment.
When spraying hold the nozzle 30 - 50
cm from the target.
Always wash off any skin contamination
Always clean all equipment after use.
When mixing chemicals follow the label instructions for use with a knapsack sprayer.
CLEANING AND MAINTENANCE
After spraying always flush out the backpack and lance with clean water and dispose
of the residues according to the product label. Disconnect the lance from the
backpack at the tap and allow to dry thoroughly. Store in a clean dry place.
