CONTROLS AND INDICATORS
All controls and indicators to operate and monitor crane
functions are found inside the crane cab (Figure 3-1).
Steering Column
The steering column assembly (5, Figure 3-1) is a pedestal
style tilt and telescoping steering column. It can tilt rearward
30° or raise vertically 60 mm (2.3 in). It includes the ignition
switch and other control switches (Figure 3-2).
Turn Signal Lever and Windshield Wiper/
Washer/Headlight/Horn Controls
Turn Signal Lever and Windshield Wiper/Washer Controls
(1, Figure 3-2) are located on the left side of steering column.
Pushing the turn signal lever down causes the left front and
left rear turn signals to flash. Pushing the turn signal lever up
causes the right front and right rear turn signals to flash.
The windshield wiper switch is built into the turn signal lever.
The knob of the lever has four positions: J (interval wiping),
O, I, and II. Pushing the knob inward energizes the
windshield washer pump to spray washer fluid on the
windshield. Turning the knob to position I causes the wiper to
operate at low speed. Turning the knob to position II causes
the wiper to operate at high speed. Turning the knob to
position O turns the wiper motor off and automatically returns
the wiper to its parked position. Turning the knob to position J
causes the wiper to operate intermittently.
Pushing the small button on the end of the lever operates the
horn.
