is in the "ON" position. See "Care of your Waterpik
Water Flosser" for guidance on how to look after
your battery. The Waterpik Water Flosser will stay
®
charged for up to 2 weeks depending on use.
Filling the Reservoir
Remove the charger from the unit prior to
filling reservoir and product use. Lift flip
top on reservoir and fill the reservoir with
lukewarm water.
Inserting and Remove Tips

Adjusting the Pressure Setting
You can adjust the pressure setting on your Water
Flosser by sliding pressure control on the handle.

your liking.
Recommended Technique
Lean low over sink and place tip in mouth. Aim
the tip toward gumline, and turn the unit ON (I).
For best results, start with the back teeth and
®
work toward the front teeth. Glide tip along gumline and pause briefly
between teeth. Continue until you have cleaned the inside and outside of
both the upper and lower teeth.
Direct the jet stream at a 90-degree angle to your gumline. Slightly
close lips to avoid splashing but allow water to flow freely from mouth
into the sink. Keep unit upright during use for best results.
