INSECDISK MODEL. ULTRA LOW VOLUME BATTERY – OPERATED SPRAYER FOR THE APPLICATION OF INSECTICIDES.
EN
OUTSTANDING FEATURES
- Clearly specified working nozzle. After mounting the nozzle holder disk on the motor carrier head, only the chosen nozzle can be seen to avoid
any possible mistake.
- Easy access to the motor. Loosen two screws and remove the cover with the connection elements, thus leaving the motor unattached in its
housing. To take it out, simply turn the unit upside down.
- There are no wires in the battery area as power from the positive terminal of the batteries is fed to the unit through a conductive tube.
- All connections are located inside the battery carrier tube; this makes it possible to have a tight tube and prevents liquid from reaching the
connections.
- Easy access to all sprayer components. You just need a screwdriver to disassemble the unit.
- There is a cap provided for connection of the hose from the supply tank. This cap is fastened to the tank holder so that it cannot be lost. The
cap can be hooked up on a pin in the tank holder when using the supply tank so that it will not interfere during the spraying operation.
- All the components making up this unit are made of first–class materials.
- This TELESCOPIC unit makes storage easier, as its sections slide one within the other.
- The protective hood over the spinning cog for storage and transportation, which is built in so it cannot be lost.
- Its four versatile, easy to select, nozzles for different dosages, all on a protected disc which cannot be lost.
- It is easy to change, repair and service the battery, spinning cog, fixed disc, motor, etc.
- Cables and tubes are protected, and run through the inside of the device, which is more functional and prevents snagging, deformation and
breakage.
- Light, easy to handle sprayer.
- Strong, adjustable, non corrosive oriented strap with a width of > 3 cm.
STARTING-UP
INSERTING OR CHANGING THE BATTERIES
To insert or change the batteries do as indicated in figure B, loosening the protective hood of the spinning cog wheel from the battery holding
tube.
Once the hood has been removed, insert five 1.5 V batteries (type R-20). Ensure that the position of the battery is as shown in the figure B.
REPLACING THE MOTOR
To replace the motor follow the following steps, according to the detail drawing of part no. 687.
1) Remove the selector disk (688) and the distributor disk (311)
2) Loosen the screws (520) and remove the cover (689).
3) Turn the Insecdisk upside down so that the motor will drop by its own weight.
4) Introduce the new motor (945).
5) Re–assemble the cover (689), taking care that the red lead coincides with the terminal marked with a red dot in the motor. Tighten the screws
(520).
REMOVING THE SPINNING COG WHEEL
To remove the distributor disc, fully press the two clamping flanges which stand out and remove it carefully.
CHOOSING THE NOZZLE
Once you have removed the distributor disc, you will find another fixed disc inside housing the colour markers.(See figure D.)
The equipment has two nozzles for 10 L/Ha. (black mark) and two for 3 L/Ha. (grey mark), and is supplied from the plant with the black mark
set on the colour selection arrow. As you will see in the enclosed table, black means using a nozzle of Ø 1.85 mm. with a flow rate of 10 l/Ha,
working at 3.6 km/h (1 m/s) with a working width of 2.4 m.(wind assisted), at 6.700 r.p.m. and obtaining an average drop size (vdm) of 140
microns.

COLOUR Ø
Black 1,85 mm.
Grey 1,30 mm.
If you want to select a different flow rate, just point the grey colour-selecting arrow to this colour and adjust the fixed disc. Then fit the distributor
disc wheel very carefully. Pay the utmost attention to placing it exactly in its original position: not fitting this cog correctly would result in irregular
spraying as affecting dosage and distribution.
CALIBRATION CHECK
From the formula:
10.000
–––––––––––––– = minutes/Ha
W x S x 60
(W= Working Width .– S= User Speed in m/sec.)
we find how long it takes to treat one hectare. Let us apply our parameters to the formula:
10.000
Black Nozzle = ––––––––––––––––––––––––– = 70 minutes
2.4 m. x 1 m/sec x 60
it will take 70/35 minutes to treat one hectare. This may be expressed as in the following table:
USER
NOZZLE SPEED
Black 1 m/sec.
Grey 1 m/sec.
Variations of plus or minus 20-30% are logical, due to the viscosity of the material used and the mixture prepared.
The desired dose can be adjusted not only via the nozzle, but also via such simple variables as user speed and working width.
SPRAYING TECHNIQUES
The indications and layouts given below are merely illustrations aimed at helping you use the equipment correctly.
In sketches J and J1 (page ...) we can see a bird's-eye view and a rear view of the working lay-out needed to apply well and take advantage of
the wind. These drawings indicate the most widespread use: this is for a dose of 3 l/Ha for side winds of 5-25 km/hr and crops laid out in lines,
with a planting mark at 0.80 m. With this technique 6 lines, or 4.8 m. are treated with each pass.
These ultra-low volume treatments (3 l/Ha) have given way in recent years to very low volume treatments (10 l/Ha) in order to control properly
certain resistant pests.
In this last case (see drawings K and K1 on page ...) the dose is 10 l/Ha. With the same wind characteristics, crops and
with a higher flow-rate and therefore bigger drops, only 3 rows, i.e. a width of 2.4 m, is reached.
