PNEUMATIC BACKREST ADJUSTMENT
Required Tools:
1/2” Wrench
5/32” Allen Wrench
Locktite
3/32” Allen Wrench
Adjustment Procedure:
1.
For easier access, move backrest to 75 degrees.
NOTE
Before continuing with the backrest adjustment procedure, be sure the cylinder (item A) is completely
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 remove the E−clip
and pin (items D & E) holding the bottom of the pneumatic cylinder. Thread cylinder shaft (item A) completely
into yoke (item B). Replace the E−clip and pin (items D & E) and replace the set screw (item C) using Locktite.
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.
Be sure 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.
