! For your safety and the safety of others, the following precautions must be observed when operating the sprayer:

1. During spraying operation, the personnel shall wear clothes in strict accordance with the regulations, wear masks, glasses, hats, gloves, or protective clothing against pesticide penetration, and shall not work naked.
2. It is strictly prohibited to spray toxic solutions such as pesticides on people or animals during use.
3. Patients with mental illness or serious diseases, drunken people, and people without operation knowledge are prohibited from using this machine. People who have just taken strenuous exercise, have not had a good rest, or have insufficient sleep, as well as women in the period of lactation, should not be engaged in this work.
4. The operator must wash all parts of the body and clean all kinds of clothing after use.
5. When handling pesticides, follow the safety instructions provided by the pesticide manufacturer.
6. Do not use the special liquid.

WARNING:

1. Do not leave machines and tools unattended or store them in unattended places. Turn off the power when not in use.
2. Do not disassemble or modify this machine.
3. Operators must spray pesticides in front of the wind direction and shall not work under high temperatures for a long time.
4. Before each use of the battery (including the new machine), please charge the battery for 4-8 hours. When the battery is not charged, cover the charging port tightly to prevent water from getting in.
5. Try to avoid working without water to avoid damaging the diaphragm of the

water pump.

1. Before use, try spraying with clean water to check whether there is water leakage at the base and whether the atomization effect is good. Only when everything is normal can you prepare liquid medicine for the operation.
2. When adding liquid medicine, it must pass through the filter screen. If impurities enter, the normal use of the machine will be affected.
3. If the liquid medicine overflows, please dry it immediately. Battery connected electrical components and wire connectors shall not be exposed to liquid medicine to avoid corrosion.
4. Please do not use non-water bath powder because it cannot be dissolved in the liquid. The suspended solids in the medicine tank will precipitate at the bottom, causing clogging of the filter screen and pipeline, thus affecting the service life. The use of chemical liquids and special working fluids is prohibited.
