Standard and Comfort nozzles:
1. Make sure that the pause switch on the handle is in the 'off' (down) position.
2. Press the on/off button on the base to turn on the product.
3. Place the nozzle tip in your mouth. Lean over the sink and partially close your lips over the nozzle to avoid splashing. Leave enough space to allow water to flow from your mouth into the sink.
Note: Position the nozzle tip just above the gum line at a 90 degree angle.
Starting from your back teeth in your upper or lower jaw, slide the nozzle tip along the gum line and pause briefly between each tooth. Continue to clean both inside and outside of your teeth in one arch of your mouth for 30 seconds.
