5. Referring to Fig. 3, attach the 2nd section maker weldment(# 28) to the breakaway hinge (# 10) by passing the pivot
pin (# 29)through the pivot hole in the hinge and weldment. Retain the pivot pin (# 29) with the bolt and lock nut (# 8 &
9). Complete this joint by passing the special GRADE 2 breakaway bolt(# 30)through the holes in the hinge and 2nd
section. Install the lock washer (# 31) and nut (# 32) on this bolt.
NOTE: The breakaway bolt (# 30) is a 7/16"-14 x 2" long - grade 2 (G.P. # 802-353C) It is identified as a grade 2 by
having no marks on the head. If it breaks, it must be replaced by an equivalent grade 2 bolt to prevent marker damage.

6. Referring to Fig. 4, attach the 3rd section (# 33) to the 2nd section (# 28) by using the pivot pin (# 29). Retain the
pivot pin with the bolt (# 8) and lock nut (# 9).
Note: The next few steps are made easier if the marker's outer sections are lifted off the ground by a support approxi-
mately 12" to 18" tall placed under the outer end of the 3rd section (# 33).
Pull the loose end of the chain and chain bar (# 27) out and fasten the chain bar to the ears on the 3rd section (# 33) by
using the bolt (# 34) flat washers (# 35) and lock nut (# 36). Do not over tighten this pivot and cause the ears to bend
in. The chain bar must pivot freely around the bolt.
