Recline Bar Replacement
Tools needed: Needle nose pliers, P2 Phillips screwdriver, T30 screw bit, wire cutters, zip
ties, 3/8 inch socket, a stool or stand for placing the chair upside down.
1. Unplug the transformer from the wall outlet.
2. Reach down into the chair’s side pocket until you feel the disconnect latch on the hand control
extension.
3. Pull back on the disconnecting latch.
4. Put one hand on the back of the extension wire plug base and one on the hand control plug
base and pull the two pieces apart.
5. Gently push the chair over onto the footrest, turn it upside down or, gently push it over onto its
side, opposite of the hand control.
6. Remove the four (4) T30 lag screws, eight (8) on models (540M-26, 542M-26, 542-ME6,
550-M26) that hold the lift frame to the arm assembly.
7. Remove the hitch pin(s), clevis pin(s), and washers that fasten the recline strap(s) to the recline
bar.
8. Remove the hand control extension wire clamp.
9. Lift the lift frame out of the chair shell and place it off to the
side.
10. Use the 3/8 inch socket to remove the two (2) bolts that
fasten each scissor mechanism to the arm assembly.
While this next step can be done alone,
it does require extra attention. You must remove the
arm assembly without twisting the frame. Excessive
twisting will cause the board holding the arms together
to snap.
11. Stand behind the chair and pull the arms away from the
chair being careful not to get the material snagged in the
scissor mechanisms.
12. Place the arm assembly to the side.
13. Use the 1/2 inch socket to remove the bolts that fasten
the recline bar to the seat.
Note the position of the recline bar,
so you do not install the new bar in upside down.
14. Use the 1/2 inch socket to install the bolts that fasten the new recline bar to the seat.
15. Place the arm assembly in place so that the bolt holes in the scissor mechanisms line up with
the bolt holes in the armrest.
16. Install the two (2) bolts that fasten each scissor mechanisms to the arm assembly.
17. Make sure the footboard is completely closed.
Note: When installing the lift frame the footboard must be completely closed when you
fasten the lift frame to the armrest assembly or the footboard will not close properly.
Note: Seat bar on StellarCom-
fort models only.
