Safety Instructions
⚠️ For your safety and the safety of others, the following precautions must be observed when operating the sprayer:
- During spraying operation, personnel shall wear clothes in strict accordance with regulations, wear masks, glasses, hats, gloves, or protective clothing against pesticide penetration, and shall not work naked.
- It is strictly prohibited to spray toxic solutions such as pesticides on people or animals during use.
- 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.
- The operator must wash all parts of the body and clean all kinds of clothing after use.
- When handling pesticides, follow the safety instructions provided by the pesticide manufacturer.
WARNING:
- Do not leave machines and tools or store them in unattended places. Turn off the power when not in use.
- Do not disassemble or change this machine.
- Operators must spray pesticides in front of the wind direction and shall not work under high temperature for a long time.
- Before each use of the battery (including the new machine), please charge the battery for 8-12 hours. When the battery is not charged, cover the charging base tightly to prevent water from getting wet.
- Try to avoid working without water to avoid damaging the diaphragm of the water pump.
- Before use, try spraying with clean water to check for water leakage at the base and good atomization effect. Only when everything is normal can you prepare liquid medicine for the operation.
- When adding liquid medicine, it must pass through the filter screen. If there are impurities, the normal use of the machine will be affected.
- If the liquid medicine overflows, please dry it immediately. Battery connectors, electrical components, and wire connectors shall not be exposed to liquid medicine to avoid corrosion.
- Please do not use non-water bath powder, because it cannot be dissolved into liquid. The suspended solids in the medicine tank will precipitate at the bottom, causing clogging of the filter screen and pipeline, thus affecting the pump's service life. The use of chemical liquids and special working fluids is prohibited.
- When the liquor spraying is completed, turn off the power switch or regulating switch first, and then release the injection switch after the pump stops working.

Cleaning, Care and Storage Rules
Cleaning and care:
After operating the sprayer, remove the working solution from the tank completely and rinse the tank, hose, pump, and spray tube with clean water. Finally, spray with clean water for 3 minutes to eliminate the possibility of a chemical reaction when other chemicals are used in the next spraying. Residues of chemicals can lead to corrosion and other damage to parts of the sprayer, especially spraying nozzles, filters, and seals.
Storage rules:
- Keep the sprayer in a dry, cool, and out-of-way place for children.
- It is forbidden to store the sprayer near an open fire.
- To prevent damage to the pump and other parts, it must be washed and dried before storing the sprayer in winter. Clean the surface of machines and tools, filter screen, and nozzle, and dry them in the air. Do not put them directly in the sun.
- Before storage, the battery must be fully charged. During the storage period, you need to charge your battery regularly with an adapter (at least once every 2 months).
- Keep the adapter in a dry place.
