CLEANING & MAINTENANCE
After use, the sprayer must be thoroughly decontaminated, inside and outside.
Decontaminating the tank, including pumps, hoses and hand lance, avoids damage to
crops from harmful spray residues and prevents sprayer corrosion and abrasion. As a guide,
follow the decontamination procedure below:
1.
After spraying, rinse all liquid out of the tank.
NOTE:
When flushing the sprayer, pay attention to where the chemical will run.
Always clean in an area that will not contaminate water sources or crops.
2.
After draining the tank, rinse the inside by spraying clean water with a pressure
washer.
3.
Turn the pump off and fill the tank with clean water and a recommended cleaning
liquid.
NOTE:
to ensure any pesticide residue is removed from the tank, let the water and
cleaning solution sit for 8 hours.
4.
The suction filter mounted on the sprayer frame must be cleaned regularly. Unscrew
the filter cover and remove the filter screen and gasket. Soak in clean water,
brushing with a nozzle brush. Ensure gasket is in position when re-assembling.
5.
The filter basket strainer is removed by lifting it out of the filler ring. Clean the basket
strainer the same way as the suction filter. Replace the basket strainer by exerting a
quick downward push ensuring the strainer has seated correctly.
6.
Nozzles, nozzle filters, nozzle caps and gaskets should be cleaned by soaking in
water, brushing with a nozzle brush and allowed to dry. Never blow through the
nozzles with your mouth or use wire or pins to clear blockages. When re-assembling,
ensure that the nozzle cap gasket is correctly positioned.
7.
Ensuring all nozzles, filters etc. are back in place, flush the water through the entire
system; turn the pump on and spray the clean water through the booms and hand
lance.
Mounted sprayers tend to be unstable when removed from the tractor. Make sure they are
safely chocked before leaving them.
When storing the sprayer, ensure that it is clean and dry. Keep in a well ventilated place.
