PNEUMATIC BACKREST ADJUSTMENT
Required Tools:
1/2” Wrench
5/32” Allen Wrench
Loctite
3/32” Allen Wrench
7/32” Allen Wrench
9/16” Wrench
Adjustment Procedure:
1. For easier access, move the backrest to 75 degrees.
NOTE
Before continuing with the backrest adjustment procedure, be sure the pneumatic cylinder (item A) is com-
pletely threaded into the yoke (item B) so no threads are showing on the shaft of the cylinder. If threads are
showing, use a 3/32” Allen wrench to remove the set screw (item C) in the center of the yoke and a 7/32” Allen
wrench and 9/16” wrench to remove the nut and bolt (items D & E) holding the bottom of the pneumatic cylin-
der. Thread cylinder shaft (item A) completely into yoke (item B). Replace the nut and bolt (items D & E)
and replace the set screw (item C) using Loctite.
2. Using a 1/2” wrench, loosen the hex nut (item F) on the backrest pivot (item J) while holding the set screw
(item H) fixed in the pivot.
3. Using a 5/32” Allen wrench, turn the set screw (item H) until there is no play between the backrest release
handle (item K) and the pneumatic cylinder release button.
4. Verify the backrest will travel from flat to at least 75 degrees. If it doesn’t, turn the set screw (item H)
clockwise 1/2 turn. Repeat until at least 75 degrees of travel is achieved.
5. Lower the backrest to a 5
−
10 degree angle and release the handle. Apply approximately 50 pounds
downward force to the end of the backrest. If the backrest drifts down, turn the set screw (item H) counter-
clockwise. Repeat until the backrest does not drift downward.
6. Using the 1/2” wrench, tighten the hex nut (item F) while holding the set screw (item H) fixed in the pivot.
