Standard Cleaning

ATTENTION! For cleaning between spray jobs, where crops are not very sensitive towards chemicals just sprayed.
1. Engage the pump with tractor in idle, so that pump speed is as low as possible (approx. 560 rpm).
2. Turn the suction valve to
approximately 1/3 of the RinseTank contents into the main tank.
It is important to have full agitation for approximately 20 seconds; and then close the agitation valve completely.
3. Turn the suction valve to
seconds.
4. Switch all boom sections ON. Spray until air comes out of nozzles. Engage FlexCapacity pump.
When the pressure drops, close the regulation valve by pressing the
yellow LED lights on the valve (this can take up to 10 seconds).
Press "auto" to have the system remove pressure spikes automatically before next start-up.
Repeat the Following Three Steps 5 Times:
5. Turn the suction valve to
content into the main tank.
6. Turn the suction valve to
7. Switch all boom sections ON. Spray until air comes out of nozzles. Engage FlexCapacity pump.
When the pressure drops, close the regulation valve by pressing the
yellow LED lights on the valve (this can take up to 10 seconds).
Press "auto" to have the system remove pressure spikes automatically before next start-up.

Cleaning and Maintenance of Filters

Clean filters ensure:
• Sprayer components such as valves, diaphragms and operating units are not hindered or damaged during operation.
• Nozzle clogging do not occur while spraying.
• Long life of the pump. A blocked suction filter will result in pump cavitation. The main filter protecting sprayer
components is the suction filter. Check it regularly.

Use of Cleaning Agent

It is recommended to use an appropriate cleaning agent suitable for cleaning agricultural sprayers.
• Cleaning agents containing a suitable lube or conditioner are recommended.
• If for some reasons this is not available, and triple ammonia water is used instead, it is important to rinse the liquid
system immediately after, and add some lubricant to the rinsing water to prevent ball valves etc. seizing up.
• Use of automotive antifreeze/radiator coolant (ethylene glycol) will protect valves and seals from drying or seizing up.
