4.4 BOOM ELEVATION
Elevate boom to desired height by use of the BOOM "UP/DOWN"

NOTE
IN THE EVENT OF HYDRAULIC PRESSURE LOSS, THE BOOM

4.5 BOOM EXTENSION
(a) The inner boom may be extended to desired position by use of
the BOOM "IN/OUT" Control.
(b) Before operating any control handles, observe the winch cables to
make sure they are free and have sufficient slack to allow boom to
extend. If not, pay out sufficient cable by either (1) or (2):
() Operate CABLE "IN/OUT" Control.
() Disengage winch drum by pushing in the winch clutch control
handle and rotating it 90°. This will allow the winch drum to free
wheel and cable may be pulled out by hand. After sufficient
cable has been pulled out rotate the winch clutch control
handle 90° to allow winch to re-engage.
