Use and maintenance of sprayer

1. Insert the crank handle of the sprayer into the crank clamp and the gear box, then tighten the wing nut, and try to shake in the direction of rotation indicated by the arrow on the barrel. If there is no noise, it means normal.
2. First connect the powder spraying head and the powder spraying pipe, tighten the screws on the large tightening ring, and then put the ribbed end of the powder spraying pipe into the groove of the hose.
3. The added powder should be kept dry, and there should be no debris, such as wood chips, gravel, mud, fiber, etc. The switch must be turned off when adding powder, so as to prevent powder from leaking into the fan part through the switch hole, causing powder to accumulate and unable to shake.
4. Adjust the opening of the powder door switch according to the type of powder, the degree of dryness and wetness, and the amount of powder spray required per acre. Note that the switch cannot be opened to large at a time, it should be opened gradually as needed. When spraying powder, people should walk upwind. When not spraying powder, the switch should be turned off to prevent powder from leaking into the fan through the switch hole, causing powder accumulation.
5. The powder injection pipe of the sprayer and the fan components are connected by hoses, which can swing freely up and down, left and right according to the operation requirements. But be careful not to squeeze the hose, block the air duct, and cause the fan to accumulate powder.
After the spraying work is completed, the residual powder in the barrel should be wiped clean, and the powder spraying tube should be removed. The residual powder inside and outside the tube should also be removed, and then shake it for a few rotations to blow out the residual powder in the fan to prevent the powder from accumulating and being damp. Agglomeration blocks the passage, corrodes the barrel and parts, and even affects the service life.

When storing for a long time, it should be removed in order to remove the accumulated powder, and wipe it with a damp cloth if necessary (be careful not to leak water into the gear box). At the same time, engine oil should be added to the gear box. During storage, all parts such as spray parts, crank handles, and barrel body must be wiped clean one by one, and placed in a dry place without corrosive gas to prevent parts from being scattered and damaged by corrosion.
