2. Assemble the Sprayer
   

   Attach the hose securely to both the sprayer unit's motor head and the spray wand. Ensure all connections are tight to prevent leaks. Secure the motor head onto the reservoir using the integrated clips.

3. Fill the Reservoir
   

   Unscrew the lid of the reservoir. The lid features a scale and can be used as a measuring cup for precise liquid mixing. Pour the desired liquid into the 1-gallon (4L) reservoir. Do not exceed the maximum fill line. Securely fasten the lid after filling.

4. Attach Shoulder Strap
   

   Connect the shoulder strap to the designated attachment points on the sprayer unit. Adjust the strap length for comfortable carrying during use.

Operating Instructions

1. Power On/Off
   

   Press the power button located on the motor head to turn the sprayer on. Press it again to turn the sprayer off.

2. Adjust Nozzle
   

   Rotate the nozzle at the end of the spray wand to adjust the spray pattern. You can select between a fine mist, a wide fan spray, or a direct jet stream, depending on your application needs.

3. Continuous Spraying
   

   The spray lever on the wand includes a push-button switch. Press this switch to lock the lever in the 'on' position, enabling continuous spraying without holding the trigger. Press again to release.

4. Extend/Retract Boom
   

   The spray boom can be extended from 46.5cm to 73cm (approximately 18.3 inches to 28.7 inches) to reach higher plants or further areas. Adjust the length by pulling or pushing the boom as needed.

5. Storage During Use
   

   The handle features a hollow design, and the reservoir has a hose slot. These are designed to hold the water pipe and spray rod when the sprayer is temporarily not in use, keeping components organized.

Maintenance

1. Cleaning After Use
   

   After each use, empty any remaining liquid from the reservoir. Fill the reservoir with clean water and spray until it is empty to flush the internal system and prevent chemical residue buildup. For thorough cleaning, the unit can be disassembled to rinse the reservoir and wand components separately. Rinse all parts with clean water.

2. Battery Care
   

   Store the battery in a cool, dry place when not in use. Avoid exposing the battery to extreme temperatures (hot or cold). Recharge the battery regularly, even during periods of inactivity, to help prolong its overall lifespan.

3. Storage
   

   Store the sprayer in a dry, protected area, away from direct sunlight and freezing temperatures. Ensure the reservoir is empty and clean before long-term storage.

Troubleshooting

• No Spray or Weak Spray
  

  Check the battery charge level; recharge if necessary. Ensure all connections, including the hose to the sprayer unit and wand, are secure and leak-free. Verify that the nozzle is not clogged and clean it if blockages are present. Inspect the hose for any kinks or obstructions.

• Motor Runs Continuously (without spraying)
  

  Confirm that the spray lever on the wand is not accidentally locked in the 'on' position. Check for any visible leaks in the system, as pressure loss can cause the motor to run continuously.

• Battery Indicator Not Working
  

  If the battery fuel meter does not display correctly, it may indicate a sensor issue. The sprayer may still function, but it is advisable to monitor usage time to avoid unexpected power loss during operation.
