Setup

1. Charging the Battery

1. Insert the 18V ONE+ Lithium-Ion battery into the charger.
2. Plug the charger into a standard electrical outlet.
3. Allow the battery to charge fully. The indicator light on the charger will change color (refer to charger manual for specific indications).
4. Once charged, remove the battery from the charger.

2. Attaching the Spray Wand and Hose

• Connect the spray hose to the outlet port on the sprayer unit. Ensure a secure, leak-free connection.
• Attach the spray wand to the other end of the hose.

3. Selecting and Attaching a Nozzle

• Choose the appropriate nozzle for your application: the adjustable spray nozzle for varied patterns or the flat fan nozzle for broad coverage.
• Thread the selected nozzle onto the end of the spray wand until hand-tight.

4. Filling the Tank

• Ensure the sprayer is on a level surface.
• Unscrew and remove the tank cap.
• Carefully pour the desired liquid (e.g., herbicide, insecticide, fertilizer) into the 4-gallon translucent tank. Do not overfill.

Operating Instructions

1. Wearing the Sprayer

• Adjust the backpack straps for a comfortable and secure fit. The sprayer should sit evenly on your back.

2. Powering On and Adjusting Pressure

• Locate the power switch on the sprayer unit and turn it to the "ON" position.
• Use the variable dial to adjust the spray pressure to your desired setting. Higher settings provide a stronger spray, while lower settings conserve liquid and battery life.

3. Spraying

• Aim the spray wand at the target area.
• Depress the trigger on the spray wand handle to begin spraying. Release the trigger to stop.
• For continuous spraying, engage the trigger lock if available on your model.
• Adjust the nozzle as needed to change the spray pattern (e.g., fine mist, stream).

4. After Use

• Turn the power switch to the "OFF" position.
• Relieve any remaining pressure in the tank by briefly depressing the spray trigger (ensure no liquid is left to spray).
• Remove the battery from the sprayer.

Maintenance

1. Cleaning the Sprayer

• After each use, especially with chemicals, thoroughly rinse the tank, hose, and wand with clean water.
• Run clean water through the pump and nozzle to flush out any residue.
• Wipe down the exterior of the sprayer with a damp cloth.
• Do not submerge the motor housing in water.

2. Nozzle and Filter Maintenance

• Periodically check nozzles for clogs. Clean them with a small brush or by rinsing.
• Inspect the in-tank filter (if applicable) and clean it as needed to ensure proper flow.

3. Storage

• Store the sprayer in a cool, dry, and frost-free location.
• Ensure the tank is empty and clean before storage.
• Remove the battery from the sprayer during extended storage.
