Replacement Procedure
(10) How to Remove A Massage Unit
1, Cut four bands and remove upside of the
cover (back cover under).
2, Remove eight cover (back cover) set screws,
take off the cover (back cover upper) and
the cover (back cover lower).
3, Move the massage unit upwards to its top position.
Usually the massage unit is at a stop at its top
position. When the massage unit is at a stop
halfway, however, turn on the power and make
the massage unit move up to its top position.
At the top position, when the massage unit
comes to a stop, pull out a POWER plug.

exercise care so as not to come into contact

If the massage unit does not move upwards
when the power is turned on, turn a pulley
(elevation) clockwise to move the massage
unit to the top position.

mark on the cords before disconnecting the
wiring.
