10. Once the connection hole of the No.1 Fly-jib (2) and the hole
(B) of the bracket (27) on the left side of the Main boom tip are
adjusted, insert the position pin (16) to the hole then secure it
with the linchpin (25).
Detach the linchpin (25) for the position pin (16) from the hole for
storage at the boom tip and apply to the position pin (16).
The position pin (16) must always be inserted downward
from the upper side. Otherwise, if it is inserted upward
from the underside, the position pin could easily drop down
to cause the Fly-jib to collapse causing a serious hazard.
