IGNITION Switch (50). The switch is located at the lower right side of the front console
panel, right of the steering column. It is a non-keyed switch with four positions; ACC (3),
OFF (0), RUN (1), and START (2). The switch is spring-returned from start to run. With the
switch in the OFF position, all electrical power in the carrier is off. Placing the switch in the
ACC position energizes all electrical components except the engine fuel solenoid valve.
The RUN position energizes the same components except the engine fuel solenoid valve
also becomes energized. Placing the switch in the START position energizes the starter
relay which in turn energizes the solenoid and cranks the diesel engine for starting.
Releasing the switch allows it to spring-return to the RUN position. Placing the switch to
OFF shuts down the diesel engine.
Trailer Air Supply Control (TRAILER BRAKE) (51). The control is located on the right
side middle of the front console panel. It controls the application of air to the trailer brake
couplings located on the rear of the vehicle. Push to apply air to brake couplings, pull to
evacuate air pressure.
Odometer (MILES) (52). The odometer is located on the Speedometer (MPH/KM/H) (53)
at the bottom and shows the total distance the crane has traveled in miles.
Speedometer (MPH/KM/H) (53). The speedometer is the large gauge located on the right
middle of the front console panel. It has a dual scale calibrated from 0 to 80 mph and 0 to
Headlight High Beam Indicator (54). The indicator is located in the Speedometer
(MPH/KM/H) (53) on the upper left side. The blue indicator light is lit when the headlights
are on high beam.
Air Conditioner Temperature Control (55). It controls air temperature and turns roof-
mounted air conditioner on and off (full counterclockwise position is off).
Air Conditioner Fan Control (56). It controls fan speed of roof-mounted air conditioner.
Control knob has four positions; OFF, LO, MED, and HI.
STEERING MODE CONTROL Handle (Not Shown). Located to rear of hydraulic tank, this
handle selects which cab (carrier or superstructure) has control of vehicle steering. When
pushed in and locked, enables steering from the carrier cab. When pulled out and locked,
enables steering from the superstructure cab.
Do not use the BATTERY DISCONNECT switch as
an emergency stop switch. Moving the BATTERY
DISCONNECT switch to off will not shut down the
engine and could result in damage to the alternator.
BATTERY DISCONNECT Switch (Not Shown). Located below the battery box, this switch
energizes and deenergizes the crane's 24 VDC electrical system. When handle is turned
clockwise and locked, the electrical system is energized.
