Masseuse Ultimate Chiro - Troubleshooting: Actuator Reclining;Inclining Faults - Specific Faults; Single Direction Actuator Resolution; Safety Switch and Actuator Fault Checks

3. One actuator working on signal direction
Reference to picture 20 and 21, The “942H-2C-12DS”relay or “8050” SMD triode in Q20/Q17 fault, repair or exchange drive board
4. Backrest actuator recline whenever press reclining or inclining button
1) see picture 2, the safety switch pressed by object that cause the reset
Protect function start. To solve the fault is to remove the object from the
Safety switch cover.
2) The safety switch fault cause the mistake of the reset protect function
start. To check or exchange it .
5. One actuator fault with reclining and inclining
Use the normal working cylinder to exchange the trouble one to make sure
the fault from cylinder or drive board ( exchange the plug of both cylinder ),
If it working after exchange them, The fault is from the driver board.
If not working as before , the fault is from trouble cylinder .
exchange the fault one .
