resulting in a change of the up/down stop position.
When installing the massager on the back frame, be sure to adjust the position with the up/down
detection gear.
• Up/down detection gear position adjustment procedure
To make an adjustment, refer to the massager removing method (the back frame is tilted from the
chair).

by setting the controller manual operation UP/DOWN button to DOWN.

3. Turn the hex nut M6 counterclockwise and move the massager upward.
4. Make sure that the massager has been mounted horizontally by moving the massager to the
position shown in the Figure.
*Unless the massager has been mounted horizontally, an abnormal sound or problem may
occur.
5. Move it up to the highest position(until the massager stops) by setting the controller manual
operation UP/DOWN button to UP.
6. Peeping into the square hole of the back frame, check the position of the massager to adjust.

adjust.
When the massager has been lowered excessively : Turn the up/down detection gear
counterclockwise to adjust.
