Fuse Replacement
WARNING: Do not attempt fuse replacement without first disconnecting the
chair from the power source.
!
WARNING: Any service and/or repairs (other than replacement of the two exter-
nal fuses) shall be performed only by a qualified technician.
!
The main power fuses are located in the rear of the base assembly in the LH side plastic shroud.
Unplug the chair from the AC power source. Twisting the fuse cap counter-clockwise and
simultaneously pressing down easily replace the fuses. Carefully remove the fuse and check for
breaks in the filament or for any corrosion at the ends. If in doubt, test the fuses with an
Ohmmeter. Obtain replacement fuses at a hardware/electronics store if it they are damaged or
blown. Once the fuse has been properly inspected or replaced, place it into the cap and re-install
it by turning the cap clockwise and pressing down simultaneously. Note: If the fuse cap is not
fully inserted the unit will not function.
