Overhaul procedure

If the battery is running low, the suction force will decrease.
Replace the batteries with new ones and then check that the suction force is sufficient.
If the suction force is not recovered even after replacement of batteries, overhaul the unit according to the following procedures.

1. Remove the bent nozzle and pad. (Refer to Photo 1.)

2. Check the hose and pad for cracks, breaks, etc.

• If a crack, break, etc. are observed in the pad: Replace the pad with a new one.

3. Remove the battery case lid to remove the batteries and then loosen the 3 screws to open the handle. (Refer to Photo 2.)

4. Remove the joint and silicon tube from the pump. (Refer to Photo 3.)

5. Remove the filters from the silicon tube and the joint and remove dirt and dust with an air blower, etc..
In addition, clean the inside of the joint and silicon tube.

• If cracks, breaks, etc. are observed in the joint or silicon tube: Replace the joint and silicon tube with new ones.

6. Replace the cleaned filters into the joint and silicon tube.

Insert the filters so that they are positioned in the centers of the joint and silicon tube. (Refer to Photos 6, 7 and 8.)
When inserting the filter into the joint and silicon tube, be careful not to crush the filter. (Refer to Photos 7 and 8.)

7. Press-fit the silicon tube fully into the joint and pump to the end. (Refer to Photos 9 and 10.)

8. Install the joint and silicon tube into the handle. (Refer to Photos 11 and 12.)

9. Close the handle and tighten the 3 screws. (Refer to Photo 2.)

• Install batteries in the handle and close the battery case lid.
• Attach the bent nozzle and pad. (Refer to Photo 1.)

If the suction force is not recovered even after overhauling, it can be assumed that the pump has deteriorated. In this case, it is recommended to send the unit in for repair.

Send it to the place of purchase for repair.

*We recommend that you should make sure that no abnormalities are found in the wrist strap before sending it in for repair. *Clearly stipulate “repair only” or “repair and calibration” when sending it in for repair.
