7.16 MULTIFUNCTIONS
A. The crane can do two operations or more at the same time. This increases the
quantity of work that the crane can do.
B. Before you start, make sure that you examine or do the items that follow:

The hydraulic system works correctly and gives a sufficient flow for
multifunctioning.

Do not move the joysticks to their limit positions.

Easy and smooth movements are necessary when you do an operation for
multifunctioning.

Make sure that you increase the engine RPMs.

Monitor the area as you operate. Do not move a load unless the conditions are
safe.
CAUTION
You can only use crane movements that operate at the same time when there is
no load (or when you lift the load away from the ground).
C. Extend or Retract the Boom + Main Winch
You can extend or retract the boom and move the main hook up or down at the same
time. To do this, push the boom extend / retract pedal and push or pull the right
