FRONT REPLACEMENT INSTRUCTIONS
MODELS GH-36, GH-45, GHM-45
1) With the front arm partially extended, turn the handle until the adjuster reaches the bottom most
position. (having the arm partially extended makes it easier to turn the adjuster handle)
2) Remove the top two bolts on the front plate that keep the front arm attached
a. * CAUTION - when the front arm bolts are removed, tension still exists even though the
adjuster has been taken to the lowest level. The front arm will naturally spring to the most
upright position.
3) Remove the two snap rings that hold the cylinder pin to the front arm. Slide the cylinder pin out of the
arm, releasing the cylinder.
4) Unscrew the cylinder end of the cylinder from the upper adjuster.
5) Remove the end fitting from the rod end of the old cylinder.
6) Install the end fitting onto the rod end of the new cylinder. Use care not to damage or scratch the
cylinder rod. Dents or scratches on the cylinder rod will cause the nitrogen gas to leak, leading to the
need for another cylinder.
7) Screw the cylinder end of the new cylinder back into the upper adjuster.
8) Reattach the rod end of the new cylinder into the front arm using the pin and snap rings.
