Maintenance of Manual sprayer before use

The new cowhide bowl on the Manual sprayer should be immersed in motor oil or animal oil (avoid vegetable oil) for 24 hours before installation. When installing the plug rod assembly into the pump barrel, pay attention to placing one side of the leather bowl in the pump barrel, then rotate it, hold the stopper rod upright, and use the other hand to help press the edge of the leather bowl into the pump barrel. It can be installed smoothly, do not force it into it. Select the appropriate boom and nozzle according to your needs. The manual sprayer has several types of booms, the two-head T-boom, and the four-head direct spray boom are suitable for wide and comprehensive spraying, the U-shaped double-head boom can be used for spraying on the crop row, and the side double-head boom is suitable for row spraying. Spray the base of crops on both sides. Hollow cone mist nozzles are available in several apertures. Large holes have high flow. The mist droplets are thicker and the spray angle is larger; the opposite of the small holes, the flow rate is smaller, the mist droplets are thinner, and the spray angle is smaller. It can be appropriately selected according to the requirements of the spraying operation and the size of the crop.

Use and maintenance of Manual sprayer

When installing a 110° slit nozzle on the T-shaped spray boom of the Manual sprayer, the notch on the nozzle should be slightly deflected at an angle of about 5° to the axis of the boom, so that the spray streams of adjacent nozzles do not collide with each other. During operation, attention should be paid to controlling the height of the spray bar, so that the mist flow of each spray head overlaps with each other, and the amount of mist in the entire spray width is evenly distributed, which is suitable for spraying herbicides in an all-round way. When working with the manual sprayer, the joystick should be pressed 18-25 times per minute. When operating the Manual sprayers, do not bend over too much to prevent the liquid from overflowing and splashing on the body from the lid of the barrel. Fill the liquid medicine, and do not exceed the water level shown on the barrel wall. If overfilled, there will be a leak at the pump barrel cover during operation. When the liquid medicine in the air chamber exceeds the safe water level, the pumping should be stopped immediately to avoid the explosion of the air chamber. All leather gaskets should be fully soaked in engine oil during storage to avoid shrinkage and hardening. At the end of each day's use, a little water should be added to the spray, and all parts of the Manual sprayer should be cleaned, and then placed in a ventilated and dry place indoors.
