Setup

1. Battery Installation:

   The sprayer requires 5 x LR20 / 1.5V (D-cell) batteries (not included). Locate the battery compartment, typically at the base of the handle. Unscrew the cap and insert the batteries, ensuring correct polarity (+/-) as indicated inside the compartment. Securely reattach the cap.

2. Nozzle Attachment:

   Select the appropriate nozzle (yellow, red, or black) based on your desired spray rate and application. Gently twist or click the chosen nozzle onto the sprayer head until it is securely in place.

3. Filling the Tank:

   Unscrew the cap of the 1-liter liquid tank. Carefully pour your desired liquid product (e.g., herbicide, fertilizer, pesticide) into the tank, ensuring not to overfill. Securely screw the cap back on.

Operating Instructions

1. Power On:

   Once batteries are installed and the tank is filled, locate the power switch or button on the sprayer handle. Press it to activate the sprayer. You should hear a low hum as the motor starts.

2. Spraying:

   Point the nozzle towards the area you wish to spray. The sprayer will automatically atomize the liquid into a fine mist. Maintain a consistent distance from the target for even coverage.

3. Adjusting Spray Angle (if applicable):

   Some models may feature an adjustable spray angle. Refer to the diagram in the "Product Features" section for details on how to adjust the angle for different applications.

4. Changing Nozzles:

   To change nozzles, power off the sprayer and ensure no liquid is actively spraying. Carefully remove the current nozzle and replace it with the desired one, ensuring it clicks securely into place.

5. Power Off:

   When finished spraying, press the power switch or button again to turn off the device. Always turn off the sprayer before storing or performing maintenance.

Maintenance

• Cleaning the Tank:

  After each use, especially when changing liquid types, empty any remaining liquid from the tank. Rinse the tank thoroughly with clean water. For stubborn residues, use a mild detergent and warm water, then rinse multiple times.

• Cleaning Nozzles:

  Remove the nozzle and rinse it under running water. If clogged, use a small brush or needle to clear any blockages. Do not use harsh chemicals that could damage the nozzle material.

• Battery Care:

  If the sprayer will not be used for an extended period, remove the batteries to prevent leakage and corrosion. Store batteries in a cool, dry place.

• Storage:

  Store the sprayer in a clean, dry place, away from direct sunlight and extreme temperatures. Ensure the tank is empty and clean before storage.
