Once the adjustment is finalized (in Steps
#13-15), the Cylinder is mounted by:
I. Snap the Ball Receptor on the small end of
the cylinder on the Ball Stud in the Lower
Mount, see figure 6.
II. The quick-release end of the Gas Cylinder
is cylindrical with a knurled surface and a
round notch. Follow steps II-a, II-b, & II-c
below to install this end of the gas cylin-
der.
a. Be sure the round notch aligns with
the Ball Recess inside the receptor. To
align this notch with the ball recess,
rotate the outer sleeve until the round
notch aligns with the receptor inside.
b. Firmly grasp the knurled surface of
the outer sleeve and pull it toward the
opposite end of the cylinder. You will
see the ball receptor open up, as shown
in Figure 7.
c. Slip the open receptor over the ball
end of the Threaded Ball Stud on the
Upper Mount and release the outer
sleeve on the Gas Cylinder
III. To remove this end of the Gas Cylinder,
reverse the order of steps “II-c” and “II-b”.

• The Lower Lift Assist Assembly is
against the MARK’s Base Casting.
