V. Troubleshooting flow chart
Notes for repairing chair or replacing parts:
①Make sure the power is OFF before tearing down the wires, moving terminals or replacing
parts.
②Semiconductors (such as IC and others) are very easy to be damaged by static, so when you
touch the PCB, please make sure your body is grounding (by wearing a girding static ring), or
your hands are touching with earthing grip (household electrical appliances putting to earth, such
as fridges, washers and so on) to release all static of the body.

VII. Maintenance of the back rest
1. Disassembly of the back pad
①You can find a zip of the back pad on the top of the back rest.
②Unzip, and disconnect the connector of heating leaf, then the back pad can be removed.
③If it’s damaged, a new one should be replaced. If the heating leaf fails, you can replace it too.
④Proceed in the reverse order of disassembly when replacing a new one.
2. Disassembly and replacement the rear cover of the back rest
If disfiguring damage or crack happened, you can proceed as follow:
①Find 4 pieces of screws fixing the rear cover.
②Slacken and remove them with a plus screwdriver.
③Then the rear cover can be removed.
④If it’s damaged, a new one should be replaced.
Attention: Take care not to damage the rear cover to avoid bad external appearance. Proceed in the reverse order
of disassembly when assembling the rear cover.

④You should proceed in the reverse order of above operation if replacement needed.
Tool: a plus screwdriver
5. Disassembly of the electric filter of the motor
①Release the stopper at the bottom of back rest, turn down the back
rest forward. Disassemble the rear cover.
②You can find a box of the filter at the bottom of the massage mechanism.
③Cut the cable ties tightening the wires on the sheet-metal with wire cutters.
④Slacken and remove the screws tightening the upper and lower cover of the box.
⑤The PCB and lower cover are fixed to the sheet-metal
with 2 pieces of screws. Slacken and remove the screws.

⑥If the PCB fails, cut the wires and cable ties tightening the wires, then
replace a new one. Then connect the wires and secure it with line insulators.
⑦Proceed in the reverse order of disassembly when assembly.
Tool: a plus screwdriver
6. Disassembly of mechanical main unit
Attention: This method can be applied when the rolling motor is OK.
If the rolling motor fails, you can refer to 7.2 mentioned below.
①Slacken and remove the screw bolts, 8 pieces, fixing the cross beam
on the guide rails with a plus screwdriver.
②Cut the cable ties around the box of electric filter, find the wires
of the kneading motor, rolling motor and height inspection,
remove the line insulators with nipper pliers, disconnect the wires.
Bear in mind the connection of the wires to avoid confusion.
( The wires with blue sleeve is connecting to kneading motor,
and the red to rolling motor)
③Pull out the terminal of the width inspection, cut the cable ties
tightening the wire. Cut the wire leading to the electric filter with wire cutters.
④Find the wires of the rolling motor, connect to the wiring terminal of
24VDC (a little lower can be accepted) power supply. Turn on the power
to elevate the mechanical main unit, until it runs out of the guide rails.
⑤Then you can do what you want to the mechanical main unit.
⑥Proceed in the reverse order of disassembly when assembly.

7. Replacement of the kneading, tapping and rolling motors
Attention: The voltage of this massage chair is high and the motors are rotating in high speed, so make sure the
power is OFF before disassembly. For safety, you should remove plug from outlet.
7.1 Kneading motor（DC -24V）
①Disassemble the rear cover of the back rest, and find the belt
at top of the massage mechanism, then loosen the belt as shown
in the picture.
②Find the wire of kneading motor, and cut the cable ties
tightening the wire with wire cutters.
③Remove the line insulator covering the wires with nipper pliers, then disconnect the wires.
④Find 4 pieces of screws fixing the kneading motor to the sheet-metal, slacken and remove the screws with a
plus screwdriver.
⑤Replace a new one if it does work.
⑥Proceed in the reverse order of disassembly when replacing a new one.
Tools: aplus screwdriver, nipper pliers
7.2 Rolling motor（DC -24V）：
If the power of rolling motor is supplied from main PCB and the wires between main PCB and the rolling
motor are OK, but the rolling motor doesn’t run. In this situation, there must be something wrong with the rolling
motor or reduction box. You can follow the following instruction to replace them.
Tools: a plus screwdriver, minus screwdriver, nipper pliers, wire cutters, shifting spanner, inner hexagon
spanners, 24VDC power supply
1. First, disassemble the cover of back rest. You don’t need to disassemble the whole back rest from the seat part.
2. Slacken and remove the screw bolts and nuts fixing the cross beam on the guide rails with a plus screwdriver
