Assembly Instructions
Refer to Figure 2.
5. Pin the base end of the hydraulic cylinder (12) to the marker
mount (1) using the pin and clip (13 and 14). Remove the
plastic plugs from the cylinder ports. Pull the rod end of the
cylinder out to its maximum length. Pin the rod end of the
cylinder to the breakaway hinge using the cylinder pin (15),
flat washers (16) and cotter pins (17) provided.
6. Install the chain bar (18) on the first section (6) with the bolt
(19) and lock nut (20). The chain bar should pivot freely
around the bolt (19).
7. Install the full-threaded adjustment bolt (21) in the hole di-
rectly above the pivot bolt (19). To install, first thread one
lock nut (22) up the entire length of the adjustment bolt.
Next, push the bolt with nut through the hole. Complete the
assembly by threading a second lock nut (22) up the entire
remaining length of the adjustment bolt.
After marker assembly, use the adjustment bolt to control
folding slack. For now, turn the adjustment bolt so its head
extends as little as possible to prevent damage the first time
the marker is folded.
8. Thread a utility clevis (23) through one end of the chain (24).
Pin this clevis to the chain bar (18) using the pin and cotter
pin (25 and 26) provided. Do not fully bend the cotter pin at
this time. Thread a second utility clevis (23) through the last
link at the opposite end of the chain (24). Pin this clevis to
the rounded end of the chain bar (27) using the pin and cot-
ter pin (25 and 26) provided.
