Assembly Method
1.0 Compress the end of item G (spring retainer) until the two end forks touch each other. Slide item H (re-
lease hoop) over the end forks and rotate item G so that item H will clear the pem nuts on item G. Align
the two side through holes on item H with the pem nuts on item G. Rotate item H until the pem nuts on
item G fit into the through holes. Expand the end forks on item G to securely fit item H to item G.
2.0 Insert item K (release rod) into the opening on item H (release hoop).
3.0 Manually tighten item A (T-handle) onto the casing end of item B (gas cylinder).
4.0 Slide item D (conical bushing) over the shaft end of item B (gas spring), resting the large conical base
on top of the gas spring cylinder casing.
5.0 Slide item C (hose clamp) onto the shaft end of item B, allowing it to rest on item A (T-handle).
6.0 Insert the gas cylinder shaft partially into the spring retainer/release hoop assembly.
7.0 Insert item E (lock bushing) into the spring retainer/release hoop assembly and over the gas cylinder
shaft. Locate the ledge on item E over the end of item H without the through hole. The surface with the
angular ramp should face down as shown on page 5. Insert item F (spring) on top of item E and over
the gas cylinder shaft, slightly compressing item F under the sheet metal end of item G.
8.0 Slide the assembly down the gas cylinder shaft. Carefully position the threaded end of item K (release
rod) through the hoop/guide on item A at the end of the gas cylinder. Align the sheet metal tabs on item
G into the grooves on the casing of item B.
9.0 Slide item C (hose clamp) from the end of the gas cylinder over the fork ends of item G. Position item
C so the steel band covers the width of the sheet metal alignment tabs on item G. Using the 5/16” socket
torque wrench, securely tighten the set screw on item C (hose clamp) to 60 inch-pound torque rating.
10.0 Apply a bead of Loctite 242 thread lock adhesive to the threads of item L (set screw). Thread item L
into the pem nut located on item G (spring retainer) until the conical point on item L contacts item D
(conical bushing). Repeat for the second set screw.
CAUTION
Do not get Loctite on the pivoting surfaces of item H (release loop) or item G (spring retainer) or the lift mecha-
nism will not function properly.
11.0 Manually tighten item J (lower T-handle) onto the threaded shaft end of item B. Align item J (lower
T-handle) with item A (T-handle) by rotating item J clockwise until both T-handles are parallel.
