OPERATING CONTROLS AND PROCEDURES

Heater Control Switch

The Heater Control Switch (3) (Figure 3-4) controls intensity
of heating temperature. Turn the switch to the right
(clockwise) to open the valve for heat. (Heat comes from
heated fluid going through the heater coil.) Turn the switch to
the left (counterclockwise) to close the valve to stop fluid flow
and minimize heat.

Air Conditioner Switch

The Air Conditioning Switch (4) (Figure 3-4) controls the
operation of the optional air conditioning system. Settings
are off (O) and on (I).

Work Lights Switch

The Work Lights Switch (5) (Figure 3-4) controls the crane's
work lights mounted on the bottom front of the superstructure
cab. Press the top of the switch to turn on the work lights.
Press the bottom of the switch to turn off the work lights.

Crane Function Power Switch

The Crane Function Power Switch (6) (Figure 3-4) is located
on the overhead control panel. This spring return switch
permits the operator to activate all crane functions at once or
disconnect power from the crane functions controlled by the
remote controllers on the armrests. Pressing it turns ON all
crane functions. Pressing a second time turns OFF all crane
functions. Turn off all crane functions to prevent inadvertent
operation of functions due to bumping the controllers while
roading or any other operation.
