PNEUMATIC BACKREST ADJUSTMENT
Required Tools:
3/32" Allen Wrench
Adjustment Procedure:
1. For easier access, move the backrest to 75 degrees.
2. Using a 3/32" Allen wrench, remove the two set screws (item A) at the top of the pneumatic cylinder.
3. Allow the cylinder shroud (item B) to drop down on the cylinder.
4. Using needle nose pliers, remove the clip ring (item C), pin (item D) and spacers (item F) at the bottom
of the cylinder.
5. Turn the pneumatic cylinder shaft (item G) clockwise or counterclockwise until there is no play between
the cylinder and the red release handle (item H).
6. Reverse steps 2−5 to reattach the cylinder to the backrest.
7. Be sure the backrest will travel from flat to at least 75 degrees. If it doesn't, repeat the procedure, turning
the cylinder shaft clockwise approximately 1/2 turn. If the backrest drifts up or down, repeat the proce-
dure, turning the cylinder shaft counterclockwise approximately 1/2 turn. After the backrest is properly
adjusted, reassemble the cylinder, using Loctite on the two set screws (item A).
