Cradling Booms
The booms should always be cradled when traveling,
transporting, or parking for an extended period of time. The
booms must be folded when cradled. To cradle the booms, fold
the boom extensions in, raise the transom, and fold the booms in
toward the machine. The closer the booms get to the cradle, the
more careful you need to be while making adjustments to avoid
damage. Raise each individual boom level until it clears the outer
cradle stop (fig. 4.27). Fold the boom in toward the cradle back-
stop. When it touches the back-stop, lower the boom level until
the full weight of the boom rests in the cradle (fig. 4.28).

Booms must be in folded position
when cradled. Failure to do so may
cause boom damage.
