Install four 3-1/4" LONG Bolts (8)
through the Cap (2) holes that mount to
the back Way (upper) Tube of the MARK.

Next, install a Cap (2), followed by the
base of the Upper Mount ( 3) to the back
Way Tube, so that the Mount is sweep-
ing downward (when the MARK is in
horizontal position) and toward the left
of the machine, as shown in Figure 1.
Install four 1/4" Split Washers (9) and
1/4"-20 Hex Nuts (10) over the Bolts and
finger tighten. (See Figure 4)
10. Install four 3-1/4" LONG Bolts (8)

onto the arm of the Upper Mount, as
shown in Figure 5.
Figure 5
Install the 5/16" Split Washer (11) and
5/16" Nut (12) onto the end of the
Threaded Ball Stud and tighten.
NOTE:
Be sure the Ball is protruding toward the
back of the MARK. See Figure 1 for proper
orientation.
CYLINDER INSTALLATION
AND ADJUSTMENT
12. The next step is to install and adjust the
Gas Cylinder (13). This Cylinder was
shipped in the full extended position
and needs to be mounted while in this
position.
TRIAL ASSEMBLY
It is important to note that virtually all instal-
lations will require the adjustment of either
the Upper or the Lower Mount
Assembly.
With the MARK still in vertical position, hold
the Gas Cylinder against the Ball Studs on the
Upper and Lower Mounts and note the proper
orientation of these Studs relative to the re-
ceptors on the ends of the Cylinder. When
assembled, the Cylinder must be positioned
with its larger diameter with quick release
