Setup
- Unpacking: Carefully remove all components from the packaging. Inspect for any damage.
- Battery Charging:
Locate the 18V Lithium-Ion battery and charger. Connect the charger to a standard electrical outlet and insert the battery. Allow the battery to fully charge before first use. A full charge can provide up to 4 hours of spray time or spray up to 50 gallons.
- Attaching the Wand:
Connect the stainless steel wand to the hose connection point on the sprayer. Ensure a secure, leak-free connection. The wand is designed to be 4x stronger than poly material.
- Selecting and Attaching Nozzle:
Choose the appropriate nozzle for your application (brass adjustable, flat fan, or foaming nozzle). Screw the selected nozzle onto the end of the wand. The sprayer also accepts Tee Jet Nozzles.
- Attaching Shoulder Straps:
Attach the shoulder straps to the designated points on the backpack sprayer. Adjust the straps for a comfortable and secure fit, distributing the weight evenly across your shoulders and back.
Operating Instructions
- Filling the Tank:
Ensure the sprayer is on a stable, level surface. Unscrew the tank cap and carefully pour your desired liquid (e.g., pest control, weed control solution) into the 4-gallon tank. Do not overfill. Securely replace the tank cap.
- Powering On:
With the battery inserted, locate the power switch. Turn the sprayer ON. The high-performance motor and pump will automatically build pressure to the pre-set 40 PSI. No manual pumping is required.
- Spraying:
Once pressure is built, aim the nozzle at the target area and depress the spray trigger on the wand handle. Release the trigger to stop spraying. Adjust the nozzle for desired spray pattern (e.g., fine mist, stream).
- Monitoring Battery:
The 18V lithium-ion battery is designed to spray up to 50 gallons per charge, providing consistent application rates. Recharge the battery when performance diminishes.
- After Use:
After each use, turn off the sprayer. Release any remaining pressure by briefly depressing the spray trigger. Empty any unused liquid from the tank and rinse thoroughly with clean water. Refer to the Maintenance section for cleaning details.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your Scotts Elite Sprayer.
- Cleaning the Tank:
After each use, especially when changing chemicals, rinse the 4-gallon tank thoroughly with clean water. Spray clean water through the wand and nozzle to flush the system. This prevents chemical residue buildup and cross-contamination.
- Nozzle Maintenance:
Periodically inspect nozzles for clogs or wear. Clean clogged nozzles using a soft brush or by rinsing. Do not use metal objects that could damage the nozzle orifice.
- Battery Care:
Store the lithium-ion battery in a cool, dry place. Avoid extreme temperatures. For long-term storage, it is recommended to store the battery with a partial charge (around 50%).
- Hose and Wand Inspection:
Regularly check the heavy-duty reinforced hose and stainless steel wand for any signs of cracks, leaks, or damage. Replace components if necessary.
- Winter Storage:
Before storing for winter, ensure the sprayer is completely drained and dry to prevent freezing and damage to internal components. Store in a frost-free environment.
