Dilution kit (optional)
See “Dilution kit (optional)” on page 22 for explanation of tank and boom dilution.
Tank dilution
When the main tank is empty then dilute residual spray liquid before
returning to the farm for refilling.
1. Turn Off the main On/Off valve.
2. Select “Tank dilution” (A).
3. Fill approximately 150 litre (1/3 tank) from the rinsing tank into the
main tank.
4. Select “Spraying” (B) for at least 30 seconds.
5. Turn On the main On/Off valve and resume driving in the field to spray out the diluted spray liquid.
6. While spraying the diluted liquid, then turn the main On/Off valve to Off for at short while and then On. This also dilutes
the pressure equalization piping.
7. Repeat point 1-6 twice (until the rinsing tank is empty).
Boom dilution
When a spray job is interrupted, then chemical residues in the boom
piping must be diluted before returning to the farm.
1. Continue driving in the field with the main On/Off valve open.
2. Select “Boom dilution” (C).
3. Dilute boom piping by spraying approximately 200 litres (1/2 tank)
from the rinsing tank on the field.
4. Turn off the P.T.O. to stop dilution of the boom piping.
5. Select “Spraying” (B) to be ready to resume spraying later.
6. Turn main On/Off valve to Off and drive home.

NOTE! Do not turn the main On/Off valve to Off while diluting the boom piping. This will dilute the remaining spray
chemical in the main tank!
