Setup and Assembly
Unpacking
Carefully remove all components from the packaging. Verify that all parts listed in the packing list are present and undamaged. Retain packaging for storage or potential returns.
Battery Installation and Initial Charge
Locate the battery compartment, typically at the base of the sprayer. Insert the 11V 7.8Ah lithium-ion battery. Connect the provided battery charger to the charging port on the sprayer and plug it into a standard electrical outlet. Allow approximately 5.5 hours for a full charge before first use.
Wand and Hose Connection
Attach the spray hose securely to the outlet on the sprayer's base. Connect the 36-inch carbon fiber wand to the other end of the hose. Ensure all connections are tight to prevent leaks.
Nozzle Selection
Select the appropriate nozzle for your spraying task from the interchangeable spray nozzle system. Attach it firmly to the end of the spray wand.
Operating Instructions
Filling the Tank
Ensure the sprayer is on a stable, level surface. Unscrew the tank cap. Prepare your liquid solution according to the chemical manufacturer's instructions. Use the integrated strainer to prevent debris from entering the tank. Fill the tank up to the desired level, not exceeding the maximum capacity of 4.5 gallons. Securely replace the tank cap.
Powering On and Pressure Adjustment
Locate the two-step toggle switch on the sprayer's base. Switch it to the desired pressure setting: 36psi for lower pressure or 62psi for higher pressure. The pump will activate, and the pressure gauge on the wand will indicate the current operating pressure.
Spraying
Aim the nozzle at the target area. Press the trigger on the spray wand to begin spraying. Release the trigger to stop. Maintain a consistent distance and motion for even application.
Maintenance
Cleaning After Use
After each use, especially when using chemicals, thoroughly rinse the tank, hose, and wand with clean water. Operate the sprayer with clean water for a few minutes to flush out any chemical residue from the pump and lines. This prevents clogging and extends the life of the sprayer.
Draining and Storage
To completely drain the tank, use the drain valve located at the bottom of the sprayer. Ensure all liquid is removed before storing. Store the sprayer in a cool, dry place, away from direct sunlight and freezing temperatures. Disconnect the battery if storing for extended periods.
Battery Care
Recharge the lithium-ion battery after each use. Avoid completely draining the battery to prolong its lifespan. If storing for a long time, charge the battery to about 50% and store it in a cool, dry place. Recharge every 3-6 months if not in use.
