Always unplug the pressure washer from both the mains power and the water outlet before starting the service. Even though power and water is disconnected there may be pressurized water in the hose. Discharge this pressure by pulling the trigger on the gun.
Make sure your work area is clean and appropriate for the work you are about to do. There will usually be a small amount of water inside the pump and hose.
