Disassembly Of Massage Mechanism Block - Panasonic EP-MA03 Service Manual

9.14. Disassembly of Massage Mechanism Block

9.14.1. Adjustment of Massage Mechanism Block Up/Down Sensor Gear
When the massage mechanism is dismounted from the back frame, the position of the up/down sensor gear and, consequently, the
up/down stop position will be changed. Be sure to adjust the up/down stop position accordingly, using the up/down sensor gear.
Dismounting the Massage Mechanism Block
1. Before dismounting the massage mechanism from the back frame, use Manual Mode (CE) to move it to the top.
2. Next, rotate the up/down sensor gear by 2-4 turns in a clockwise direction (Diagram 1, below), and move the massage mech-
anism upwards.
Note: Failure to perform step 2 above will result in the up-down axle pinion becoming engaged with the back frame,
preventing it from being dismounted.
3. Remove the three screws fixing each of the rail pieces in place, and remove the rail pieces. (It does not matter whether the left
or the right rail piece is removed first. Use the appropriate jig for the first rail piece to be removed, and hold the guide roller
(round plastic component) in place.
* The jig is used to prevent the massage mechanism block toppling forwards when the rail piece is removed. This task may
still be performed without using the jig.
4. Remove the massage mechanism block from the back frame.
Note: A spring is attached to the left-hand side of the guide roller. Hold the guide roller in place when dismounting
the massage mechanism block to prevent it from springing out.
