Several precautions of handheld Sprayer
1. After buying the handheld compression sprayer, you can first apply a layer of petroleum jelly or other lubricating oil around the black rubber piston ring in the cylinder tube and the pump rod to prevent rust or malfunction. 2. When using, you'd better unscrew the lid of the liquid bucket and put the liquid into the liquid bucket. The amount of liquid filled at a time must not exceed the water level. Excessive amount will cause insufficient air pressure. After filling the liquid amount, tighten the lid of the liquid bucket. 3. You should press the wrench a few times before pumping up, and after lubricating, pull the pumping rod to pump up the air. After pumping up several times, you can spray. The standard of pumping should be based on the start of the pump handle.
4. If you pump up too many times, the pressure will increase (the safety device will fail), and the barrel will burst, so you ought to pay attention to safety! 5. You should tighten the nozzle to spray, and loosen to spray far or straight. When the air is fully inflated and the spray is not sprayed, you have to check whether the nozzle is blocked or whether the nozzle cap is tightened too tightly. It should be loosened or cleaned, and no hard pressure is allowed. 6. After fully inflating, there is no spraying, and the nozzle is dripping. You should tighten the nozzle nut. After tightening, when there is a gap in the wrench, the water still leaks. Checking whether the O-ring in the plug rod is aligned is necessary. It should be aligned. 7. If you feel the frictional resistance of the plug rod is large when pumping up, you should unscrew the air barrel tube and apply petroleum jelly or other lubricating oil around the black rubber piston ring (this should also be the case when updating the O-ring) to make the pump feel Comfortable and can also extend the service life of the rubber ring. 8. If the O-shaped rubber ring at the junction of the gas barrel nozzle and the liquid barrel lid is aging and deformed, and this accessory cannot be purchased, it can be replaced by the raw material tape used when installing the water pipe. 9. When using, you should be careful not to come into contact with substances that chemically react with plastics, and you’d better not use liquid sprays that chemically react with plastics, and do not expose them to the sun for a long time, otherwise the bottle body is prone to aging and cause the bottle body to burst. 10. After each spraying, you should spray the equipment with clean water in time to prevent the residue from clogging. When not in use, the barrel should be loosened and deflated, and the liquid should be poured. You ought to pour out the agent and clean it with clean water. It's a good choice to apply petroleum jelly or other lubricating oil to the piston and sealing ring for the next use. 11. When buying a handheld compression sprayer, you'd better not just look for cheap but not for quality.
