GAS LIFT REMOVAL GUIDE
Parts List
Use the chair lift lever to raise your office chair to the highest position. Lay the office chair on its side. Separate the two provided shaft collars
and attach them to the old chair cylinder using the shorter screws and
Allen wrench. Slide both shaft collars as close as you can to the chair
mechanism.
Tighten only shaft collar B so it clamps the cylinder very
tightly and is not able to slide. (make sure the threaded
holes in both shaft collars are not directly aligned)

Use the two longer screws to thread into shaft collar B. Using the
Allen Wrench, tighten both screws evenly so they begin to press
against the shaft collar A.
Use a rubber mallet or hammer with wooden block to strike the bottom
edge of the old cylinder until the base is separated from the cylinder.
As you continue to tighten these screws, shaft collar A will start to slide
and the cylinder wil pull away from the chair mechanism.
Please be careful when using a hammer to remove the base to
avoid injury.
