Before first use, ensure all components are securely attached. The sprayer comes largely pre-assembled, but some minor setup may be required.

3. Nozzle Selection: Choose the appropriate nozzle for your application and securely attach it to the wand.
4. Filling the Tank: Unscrew the watertight lid and use the wide-mouth opening to fill the 4-gallon translucent tank with your chosen liquid. The integrated screen filter helps prevent debris from entering the pump system. Securely fasten the lid after filling.
