1. To properly install the sprayer parts. Check whether each connection leak, use, first install water test spray, then install the medicament.
2. When the use of the official, to add water after the first medicament, the liquid surface of the drug can not exceed the safe water level. Before spraying the medicine, shake the rod more than 10 more, make the barrel pressure rise to the working pressure. The shaking rod can not be excessive force, lest the gas chamber explosion.
3. When the initial liquid medicine, due to the gas chamber and spray rod contains water, spray in the first 2-3 minutes of the liquid concentration of the low, so that the injection should pay attention to supplement, lest affect the prevention and cure effect of pests and diseases.

Common failures and troubleshooting methods in use:
The spray pressure is insufficient, the atomization is bad: if because the influent ball valve is contaminated by the dirt shelf, can remove the water intake valve, with cloth to remove dirt; if the skin bowl is broken, the new leather bowl can be replaced; if the sealing ring is not mounted because of the connection, or the seal ring is damaged, it can be fitted or replaced by sealing ring.
Spray is not fog: if the nozzle body's oblique holes are contaminated by dirt clogging, can dredge the oblique holes; but do not use wire or copper needles and other hard-to-spray holes, to prevent the expansion of the hole, so that the quality of spray poor; If the casing is blocked by the filter net or the ball put on the water valve, should clean the filter net and wash the dirt laid off the ball.
The switch is leaking or screwed: If the switch cap is not tightened, the switch cap should be tightened; if the washer is worn on the switch core, the washer should be replaced; the switch is screwed. The reason is placed longer, or used too long, switching cores due to the leaching of chemicals bonded, should be dismantled parts in kerosene or diesel oil cleaning; when there are difficulties in the demolition, can be soaked in kerosene for a period of time, demolition can be dismantled, not hard to beat.
Each connection site leakage: If the joints are loose, should screw the nut; if the gasket is not flat or damaged, the washer should be flattened, or the washer should be replaced; if the washer is hardened by dry shrinkage, it can be reused in the animal oil.
