CALCULATING BOOM FLOW PER MINUTE
To obtain the desired spray configuration, the traditional formula is used:
Boom flow
Volume width Advance
x x
hectare treated speed
= -----------------------------------------------
600
Example:
We wish to spray 500 litres/hectare with a 9 metres boom and at a calibrated tractor speed of 6.8 km/h.
We obtain:
- It is most important that maximum pump flow should satisfy the demands made on it for the desired spraying
conditions (advance speed, volume/hectare, width treated).
- The boom flow per minute should be 10 % less than maximum pump flow to ensure liquid return to the tank
and thus hydraulic agitation.
RINSING THE SPRAYER BEFORE FIRST USE
Before using your sprayer for the first time with phytosanitary product
(weedkillers, insecticide or other product), rinse the machine completely.
- Remove the nozzles if they are fitted.
- Undo the end plugs on the pipes.
- Fill 1/5th of the volume of the tank with water.
- Spray (Refer to the pump OPERATION chapter).
- Remove and clean the filters.
- Retighten the pipe end plugs.
- Fit the nozzles.
- Any foreign particles which may be in the spraying circuit will thus be eliminated and there will be no risk of
them blocking the holes in the nozzles.
CHECKS TO BE CARRIED OUT EVERY TIME BEFORE
THE MACHINE IS USED
- Check the condition of the protectors on the drive shafts.
- Make sure that there is no foreign matter in the tank.
- Check the condition of the hoist as well as the boom's lifting rope.
- Check the oil levels and the greasing of the various elements (see "lubrication and greasing" section).
- Check the cleanness filters:
- suction,
- delivery.
