the connection to the arm. The hole is for
a lever to control the vertical circular

the lever, find the two small bolts and
lever from the package.

and insert the bolts into the holes so the
ridges fit over the screws in the hole.

into the bolts. Loosen the lever to adjust.
Tighten the lever to secure.

rack and tighten the head lock screw.
