Fill the tank with the appropriate liquid. Secure the lid and use the built-in pump to pressurize. Use the wand with one of the included nozzles to apply the spray pattern best suited for your task. Use the pressure release valve before opening the tank after use.
Prior to performing any maintenance or repairs, empty the contents in the tank. Pump any remaining fluid out of the pump. Lock trigger and spray all fluid out of shut-off until all fluid and air pressure has been expelled.
