4. Remove port plugs on cylinder and carefully
unfold first marker section. Rotate hinge sec-
tion (7) into a horizontal position.
5. Align holes of break-away section (8) with
holes in hinge section. Bolt sections together
using a 5/8-inch pivot bolt (9), lock nut (10), 3/
8-by-1 3/4-inch, grade 2 shear bolt (11) and
lock nut (12).
IMPORTANT: Be sure shear bolt is a grade 2
bolt. Failure to use a grade 2 bolt can cause
marker damage.

and disk touching the ground, remove chain
slack with utility clevis (19) nearest drill.*
