Stryker Stretcher 5051

Select the section that is binding

If the neck section is binding, the 4 Phillips head screws (A) holding the neck section cover (B) must be removed.

If the head or neck section is not returning to the full lock position, use a 7/16” socket and ratchet to loosen the pivot nut (C).

If the torque block (E) is binding, use a 7/16” socket and ratchet to loosen the pivot nut (D).

If the section is still binding, check the torque block (E) for excess pressure against the gear (F). Using a 7/16” socket and ratchet, loosen the two nuts (G) holding the gear adjustment block. Tighten the nuts and verify the handle is releasing properly.

Using a 5/16” hex Allen wrench and a 5/8” box end wrench, remove the pivot bolts (item AT), washer (item F) and nut (Item AB) holding the cylinder to the leg section frame.

To adjust the Fowler, turn the gas spring 1 to 2 turns counterclockwise if the leg section will not move when actuated and 1 to 2 turns clockwise if the leg section will not hold its position.

Replace the pivot bolt (item AT) and check the leg section actuation. Rotate the handles on the leg section toward the foot end of the stretcher chair and pull outward to move the leg section. When the handle is released, the leg section should hold its position. If the leg section will not move or does not hold its position, repeat step 6.
