Important information

When you first begin using the oral irrigator, you may experience slight bleeding of the gums even though your gums may be healthy. This is because your gums are receiving stimulation by the oral irrigator for the first time. The bleeding should stop after one or two weeks of use. Bleeding that persists for more than two weeks may be indication of an abnormal condition of your gums, such as periodontal disease. In this case, stop using the oral irrigator and consult your dentist.
Do not put salt, mouthwash or other chemicals into the water tank. Doing so may cause malfunction.
Do not dry the appliance with a dryer or a fan heater. Doing so may cause malfunction or deformation of the parts.
Store the appliance in a place with low humidity after use. Leaving the appliance in a bathroom may cause malfunction.
Charge the appliance correctly according to these Operating Instructions. (See "Charging".)
This appliance contains a battery that is only replaceable by skilled persons. Please contact an authorized service centre for the details of repair.
