AGP 300 – 600 PRO INSTRUCTIONS FOR USE Rev.02/2019 11 PUMPS Pumps are a vital element of spraying appliances. The reliability and a long durability of the pump also depend on how you treat the pump and whether you use and maintain it correctly. The pump, which is integrated in the mist blower, belongs to the category of high-pressure piston diaphragm pumps that are made from approved materials for pumping plant protection products and liquid fertilizers used in agriculture, fruit growing and viticulture.
Page 52
AGP 300 – 600 PRO INSTRUCTIONS FOR USE Rev.02/2019 WARNING: Never turn on the pump’s drive when the setting on the regulator enables full load on the pump. Turn on the pump and let it run for approximately one minute under minimum pressure in order to aerate the pump and the inlet and the outlet pipes.
AGP 300 – 600 PRO INSTRUCTIONS FOR USE Rev.02/2019 11.5 Pump maintenance 11.5.1 Oil change Figure 11.2 Only use the recommended oil (see the table on the identification plate of the pump or on the oil cover of the pump). The first oil change should be performed after 10-20 hours of operation and then every 300 hours of operation or at the end of each working season.

AGP 300 – 600 PRO INSTRUCTIONS FOR USE Rev.02/2019 12 CLEANING THE MACHINE After every single use of the sprayer, the appliance must be thoroughly cleaned. The best way to use any excess insecticide is to dilute it with water and spray it on the same surface again. The concentration should be at least 10% (10 units of water per one unit of insecticide), the spraying speed slightly faster and the spraying pressure slightly lower (1.5 bar, depending on the nozzle).
Page 56
AGP 300 – 600 PRO INSTRUCTIONS FOR USE Rev.02/2019 After cleaning the sprayer with a detergent, fill at least 1/5 of the tank with clean water and repeat the cleaning process. Make sure that you have cleaned all elements that have come in contact with the insecticide or the detergent.
Page 57
AGP 300 – 600 PRO INSTRUCTIONS FOR USE Rev.02/2019 13 MAINTANCE AND STORAGE AFTER SEASON When the spraying season is over, find some time and prepare the spraying appliance for storage. Before storing the appliance, thoroughly clean the inside and the outside of the sprayer (regulator, pump, sieves, selection valves, nozzles, etc.).
Page 58
AGP 300 – 600 PRO INSTRUCTIONS FOR USE Rev.02/2019 Check the protective cover of the cardan shaft every 100 working hours and, if necessary, replace the sliding plates of the protection. Also check the condition of the cardan shaft. Pay special attention to the safety pin.
