IMPORTANT: Before cleaning the machine, first check the label, package or safety instructions of the chemical if special rinsing procedures or special cleaning agents are required.

Cleaning of the spraying equipment prevents damage. The risk of damage is particularly great when working with herbicides. However, other chemicals can also be harmful because of their mutual reaction.

After the residual liquids have been processed (see "Processing the Residual Liquids" in this section) the machine must be internally cleaned as described in "Rinse Tank" in the section entitled "Operation of the Machine". The inner tank walls must be cleaned by the operator with the tank rinsing system after each spraying job (see "Rinse Tank" in the section entitled "Operation of the Machine").

When changing to another chemical, the machine must be thoroughly cleaned with special cleaning agents:

Ammonia (9%)

• Dosage: 30 ml/100 l tank content
• Action: cleaning action

Javel water (15%)

CAUTION: Never use Javel water in combination with ammonia, as this may produce poisonous gases.

• Dosage: 150 ml/100 l tank content
• Action: cleaning action and neutralising effect on chemicals such as Ally.

Prima Clean

CAUTION: This cleaning agent must be diluted prior to use.

• Dosage: 100 g/100 l tank content
• Action: neutralises residues of chemicals

All Clear Extra

• Dosage: 500 ml/100 l tank content
• Action: neutralises residues of chemicals

According to their suppliers, all four agents may be sprayed out on the crop treated.

Discharging rinsing water or residual liquids into the surface water, the sewer or the soil is absolutely prohibited. Collect the rinsing water in a reservoir for re-use or for processing on the field.

CAUTION: Always wear means of personal protection during cleaning!

Waste water released during external cleaning of the machine must not be re-used and must under no condition be discharged to surface water, soil or sewer. If external cleaning of the machine is not performed on the field, the cleaning water must be collected separately to be processed in special waste water processing plants.

Given the costs attached to the realization of provisions for the collection and processing of waste water released during external cleaning, it is recommended to select a different option. The alternative is to externally clean the machine on the field. Research on sprayers has demonstrated that, following the external cleaning of the machine on the field, the impact on the soil is far below the permissible field spraying standard. To perform external cleaning, connect a washing brush. Washing brushes clean the machine much more thoroughly and use much less water than spray guns. During external cleaning, take due account of the electrical components; if necessary, cover them with plastic.
