SAFETY

- Successful treatment depends on correct operation of your duster.
- Correct operation depends on precise calibration of the equipment, and
this requires careful checking.
- When this checking has been undertaken, the duster must be
commissioned correctly, this also being necessary for correct spraying
and operation.
- Finally, to be certain that your duster can give you the performance you
expect, for a long time, make sure that you undertake the maintenance
operations required.
CHECKING, STARTING-UP,
OPERATION, MAINTENANCE
are therefore essential operations, and you have every reason to carefully
read the details in this booklet.
"This duster has been manufactered using materials which withstand most
plantprotection chemicalscurrently availableon themarket. Nevertheless,
BERTHOUD cannot assume responsibility for any damage resulting from
anincompatibilittyof the crop protection chemicals or productmixtures with
theplastic materials (polyethylene, polyvinylchloride, polypropylene, Vitton,
nitrile polyamide,ABS)."
CLEANING THE DUSTER
- Only BERTHOUD is qualified to assist you concerning the maintenance of
the duster and the choice of cleaning products.
- Care should be taken with products containing solvents. Such products
may attack and damage plastic and rubber elements and paint. Berthoud
cannotbe held responsibleincases where inappropriatecleaners are used.
We recommend the ALL CLEAR cleaner.
IMPORTANT
- According to the terms of article R 149 of the Highway Code, any
towed agricultural machine with a GVWR over 1.5 tonnes must be
fitted with a braking mechanism for driving on the public highway.
Because of our policy of constant product improvement,
we reserve the right to modify product specifications or design without prior notice.

GENERAL SAFETY INSTRUCTIONS
- This duster should be used by a fully trained operator in spray techniques.
- Do not allow anyone to enter the duster's working radius.
- When using hydraulic, electrical or other controls, first ensure that there is no-one within range of the spray.
- The only workpost is the tractor's cab when the duster is in operation.
- In addition to the instructions contained in this manual, comply with the legislation relating to safety and
accident prevention regulations.
- The stickers on the duster indicate safety measures to be complied with to prevent accidents.
- The user must train himself in the operation of this duster before doing any work.
- Protect yourself from spray drift during spraying.
- No passengers should be carried on the duster.
- Take care when hitching or unhitching the duster.
- Before hitching the duster, make sure that there is sufficient ballast on the tractor's front axle.
- All the remote controls must be placed so that they cannot cause a dangerous situation.
- Before doing anything on the duster, disconnect the power take-off, switch off the engine, remove the ignition
key and wait until the sprayer has stopped completely.
- Make sure that all the safety covers are in place.
- Carry out the adjustments and a water spray test before preparing the spray mixture.
- Dispose of chemical cans in accordance with the instructions given by the manufacturer.
HITCHING
- Beware of crush risks in the 3-point lifting area.
- Disconnect the power take-off, switch off the engine and remove the tractor's ignition key while the duster's
drive shafts are being connected.
- Use only EC-approved drive shafts. Fit them and service them in accordance with their manufacturer's
instructions. Replace their protectors as soon as they are damaged.
- The protective covers must always be in place and properly secured.
- Rest the drive shafts on their supports as soon as they are disconnected.
HYDRAULIC CIRCUIT
- Before connecting a hose to the tractor’s hydraulic system, make sure that the tractor and sprayer-side
circuits are not pressurized.
- Check that the hydraulic hoses are in good condition and replace them if they are damaged.
MAINTENANCE
- For all maintenance work, the PTO has to be disconnected, the tractor engine must be switched off, the
ignition key removed.
IMPORTANT: Formanually or hydraulically operated equipmentwith lifting, folding or extension gear,
etc. and prior to all maintenance work, even of minor importance, mechanical parts must be at the
limit of their travel, jack pressure off, arms on their supports and sliding or swinging frames locked
into position.
- Only use recommended spare parts by BERTHOUD.

STARTING-UP
THE DUSTER

12
- Attach the tractor’s lifting arms to the two pins on the drawbar.
- Mountthe cardan drive shaft.If necessary, cut the tube tothe required length and removeany burrs. Lubricate
thetubes.
- Attach the top link to the duster mounting pin.
- Lift the device to the required height using the lifting arms so that the drive shaft angle is as flat as possible.
The drive shaft angle must not be greater than 15° in relation to the PTO.
- PTO operating speed: 540 rpm.
- Rest the bag of powder on the rear edge of the
hopper.
While pouring it in, check that there are no foreign
bodies (pieces of bag or other) in the powder.
- Before filling the hopper, check that the opening
lever (1) is in the closed position, i.e. with the lever
in the top position, notch No. 1 (figure 1, ref. c1).
- Check that the gate (4) is fully blocking the powder
outlet aperture in the closed position (notch No. 1).
Use the nuts and locknuts (e) to adjust the position
(figure 1).

OPERATION

- Adjust the flow rate with the device powered by the
tractor PTO (540 rpm), going from:
notch No. 1 (c1) = closed position, to notch No. 8
(c8) = maximum opening.
Select the opening notch position from the flow rate
chart (see page 18).
CAUTION:
To avoid overheating and to prevent the
sulphur from solidifying we advise you:
1 - Not to use the VEGA with notch No. 1 (c1).
2 - To count 4 rows treated at a time. This
performance corresponds to the device’s
power.
3 - To drive at a normal working speed (between
4 and 6 km/h).
4 - Not to allow the VEGA run with the lever (1) in
the closed position.
With certain mixtures or sulphurs and when
theheadlandmakesitnecessaryto manœuvre,
disengage the PTO at the end of the rows.
- The product output direction lever is located on the
rightside of themachine, on theproduct feed venturi
nozzle (black knob).

- The feed pipe to the swivelling venturi nozzle is
blocked by powder adhering to the walls due to
humidity.
- Disassemble the fixed venturi by removing the
4 nuts (2) attaching it to the hopper.
- Loosen the connecting collar (3) on the
ventilationpipe.
- Clean the powder feed pipe so that the walls
arecompletely smooth.
- Before reassembling, check that the flow rate
control gate is working properly (4).
- To balance flow at the outlets:
- with the machine running:
- put the product output direction lever in the
centralposition,
- loosen the nuts (e),
- use a screwdriver to adjust the balancing
screw (v).
- Theagitator must notdisengage if thereisno foreign
body.
- To increase or decrease torque, turn the screw (v).

- These flow rates have been determined using fluid sulphur (fluidosoufre). They are therefore indicative and
significant differences may arise with powders which are more or less fluid.
- To obtain flow rates corresponding to different treatment widths, apply the following coefficients.
example:
- width 3 m: double the 6 m indications,
- width 12 m: divide the 6 m indications by 2.
