► Note
There may be some liquid remaining inside the main appliance before use (tank, water suction tube, etc), this is the remaining distilled water that was used for the performance (water flow) test, so there are no health concerns.

► Before using the appliance
Initially, bleeding may occur even with healthy gums. This is caused because the gums are not used to such stimulation. The bleeding will normally stop within 1 or 2 weeks of use. There may be a problem with the gums (periodontal disease, etc.) if the bleeding continues for over 2 weeks. In such cases, stop using the appliance and consult the dentist.

Charging the appliance

• Charge the appliance at 15 to 35 °C room temperature.
• Usage time may be shorter when charging in lower temperatures (under 15 °C). Also, it may not charge in very low temperatures (under 0 °C).
  1. Turn the switch to OFF.
  2. Store the main unit. 3. Insert the appliance plug securely into the appliance socket.
  • Insert the appliance plug after wiping any water that may be on the socket.

4. Insert the charging adaptor securely into the power outlet.
   5. Check that the charging indicator lamp glows. Charging is completed in approx. 8 hours.
   • It can be used for 15 minutes with 1 full charge.

• Leaving the main unit continuously on the charging adaptor connected to the power outlet does not affect performance. (In general, repeatedly charging and discharging the battery without fully using up the charging capacity will cause a memory effect, which decreases the usage and lowers the discharge voltage. However, this appliance has been devised in such a way that it will not affect the usage.)

• If operation stops at the start of usage (immediately after purchase or after not using for 3 months or more) or while using the appliance, be sure to charge it for 16 hours or more. If the charging indicator does not glow initially when the main unit is plugged in, wait for a short while until it does.

• The main unit will become slightly warm while charging, but this is not a malfunction.

• Charge the appliance only with the dedicated charging adaptor.
  Use the charging adaptor only for charging the dedicated appliance.

• If the usage time gets short even if charged properly, it could be that the battery is worn out.
  (Expected life of the battery is 3 years, but it can change greatly depending on how it is used and stored)

Using the appliance

• Use tap water or lukewarm water.
• Do not turn the switch ON before placing the nozzle in your mouth.

1. Open the water supply cap.

2. Pull out the white part of the main unit up to the usage line ( mark).
   • It may be hard to pull out the main unit with the water supply cap closed.
   • Water pressure will not rise unless the main unit is pulled out to the usage line.
   • Be careful since the nozzle might pop out from the storage compartment at this time.

3. Insert the nozzle into the nozzle socket holding onto the white part of the main unit.
   • Insert it securely until it clicks.

4. Pour in water.
   • Always use fresh tap water.
   • If the water feels cold, use lukewarm water of up to 40 °C.
   • Do not pour in salt, toothpaste, or chemicals.
   • To continuously use, make sure the switch is set to OFF.

5. Close the water supply cap.

6. Place the nozzle in your mouth. The water suction tube inside the tank may come out from the water and the flow of the water may stop when the appliance is tilted too much.

7. Turn the switch to ON.
   It can be used for approximately 40 seconds with a full tank.

Mode (strength) can be selected.
2 (Normal)
• For normal cleaning
1 (Soft)
• When you are worried about your gums
• When you feel 2 (Normal) is too strong

• Do not press the tip of the nozzle hard against the teeth or gums.
• Be extra cautious with those who cannot operate the appliance by themselves, such as infants or toddlers, or people with high oral sensitivity.
• Do not drop or handle it roughly.
• Do not operate when the tank is empty except to drain the water from the appliance.
  Doing so could result in malfunction.

►Tips

• Hold the appliance vertically with the nozzle upward.
• Move your face above the sink.
• Close your mouth slightly so the water will not splatter.
• Place the nozzle in your mouth.

Cleaning your mouth well

• Aim the stream as perpendicular as possible between the teeth or the edge between the teeth and gums.
• Move slowly along the teeth.
• Take extra care between the teeth and around braces.

The front side of the teeth…

• Apply the stream perpendicular to the teeth.
• Take extra care between the teeth and the edge between the teeth and gums.

The backside of the teeth…

For the upper teeth

• Adjust the angle of the nozzle to face upward, and apply the stream perpendicular to the teeth.

For the lower teeth

• Pull your chin down, and apply the stream perpendicular to the teeth.
• Do not apply the stream directly into the periodontal pockets

After using the appliance

There is a risk of bacteria propagating, so wash thoroughly and dry before storing.

1. Open the water supply cap and dispose of the water in the tank.

2. Turn the switch to ON, and drain the water inside the appliance. Run the appliance for 2 to 3 seconds until no water comes out.

3. Turn the switch to OFF.

4. Press the nozzle release button, remove the nozzle and place it in the storage compartment.

5. Store the main unit.
   • Press it in until it clicks.
   • Watch out not to clamp your fingers in the upper part of the tank.

6. Close the water supply cap.

• To store in a bag or similar after using the appliance, wrap it in a towel or similar to absorb any excess water.
• To prevent bacteria propagating, take it out from a bag or similar as soon as possible to dry.
