VEVOR Backpack Sprayer

Safety Instructions

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

• Personnel shall wear appropriate protective clothing, masks, glasses, hats, and gloves during spraying operations to prevent pesticide penetration. Do not operate with exposed skin.
• It is strictly prohibited to spray toxic solutions such as pesticides on people or animals.
• This machine is prohibited for use by individuals with mental illness, serious diseases, those who are intoxicated, or those lacking operational knowledge. Individuals who have just completed strenuous exercise, have not rested sufficiently, or are sleep-deprived, as well as women who are lactating, should not engage in this work.
• The operator must wash all parts of their body and clean all clothing after use.
• When handling pesticides, follow the safety instructions provided by the pesticide manufacturer.
• Do not use special liquids not intended for this sprayer.

WARNING:

• Do not leave machines and tools unattended or stored in unsecured locations. Turn off the power when not in use.
• Do not disassemble or modify this machine.
• Operators must spray pesticides facing the wind direction and avoid working for extended periods in high temperatures.
• Before each use (including with a new machine), charge the battery for 4-8 hours. When the battery is not charging, cover the charging base tightly to prevent water ingress.
• Avoid operating the sprayer without water to prevent damage to the diaphragm of the water pump.
• Before use, test spray with clean water to check for leaks at the base and ensure good atomization. Only proceed with liquid medicine after confirming everything is normal.
• When adding liquid medicine, it must pass through the filter screen. Impurities can affect the normal use of the machine.
• If liquid medicine overflows, dry it immediately. Battery connectors, electrical components, and wire connectors must not be exposed to liquid medicine to prevent corrosion.
• Do not use non-water-soluble powders as they cannot dissolve into the liquid. Suspended solids can precipitate, 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 spraying is completed, turn off the power switch or regulating switch first, and then release the injection switch after the pump stops working.
• Never point the spray wand at another person or animal, whether the sprayer is on or not.
• The maximum temperature of the liquid to be sprayed must not exceed 43°C. Do not use the sprayer if the ambient temperature is 45°C or lower than -10°C.
