Section 3

Operating Controls And Procedures

NOTE: The following paragraphs describe all the available (standard and optional) controls and indicators located in the cab. Some machines may not be equipped with the optional controls shown. The numbers in parenthesis ( ) represent the index number from (Figure 3-1, Figure 3-2 or Figure 3-3).

NOTE: All rocker switches except for engine diagnostics and throttle, contain one or two LED lighted slots in the switch for illumination. In addition, all but the outrigger and rear steer switches contain a LED lighted square to indicate when the switch/function is activated. The numbers in parenthesis ( ) represent the index number from (Figure 3-3).

Controls And Indicators

Defroster Switch

The DEFROSTER switch (1) is located on the right side of the front console, above the THROTTLE controls. The switch is a three-position rocker switch (HIGH, OFF, LOW) that controls operation of the defroster fan, located on top of the front console.When the switch is in the HIGH or LOW position, the square amber LED on the switch is illuminated.

Hand Throttle Control

The HAND THROTTLE control (2) is located to the right of the ignition switch. It controls engine RPM which increases or decreases proportionately with the direction it is turned. The engine rpm increases when the hand throttle is turned clockwise (fast). When the hand throttle is turned counterclockwise (slow), the engine rpm decreases. The hand throttle control is electrically connected to the superstructure control module which sends the signal to the engine ECM via the J1939 data link.

Ignition Switch

The IGNITION switch (3) is located at the bottom of the front console, to the right of the steering column. The switch is key-operated and has four positions: ACC [3], OFF [0], RUN [1], and START [2]. In the OFF position, all electrical power is off except for the lights controlled by the HEADLIGHTS switch, boom flood lights, spotlights, turn/hazard/stop lights, dome light, horn, and work light. Positioning the switch to ACC energizes all electrical components except for the start solenoid. Positioning the switch to RUN is the same as ACC. Positioning the switch to START energizes the start relay, which in turn energizes the cranking motor solenoid and cranks the engine for starting. The switch is spring returned from START to RUN. To shut down the engine, position the switch to OFF.

Voltmeter

The voltmeter BATTERY gauge (4) is located in the center of the front console to the right of the steering column. The voltmeter indicates the voltage being supplied to or from the battery and has a scale of 10 to 16 volts.

Transmission Oil Temperature Gauge

The transmission oil temperature (TRANS TEMP) gauge (5) is located in the center of the front console to the left of the steering column. The gauge indicates the transmission oil temperature on a dual scale calibrated from 60 to 160 °C and 140 to 320 °F. The gauge receives a signal from a temperature sending unit in the oil line at the torque converter.

Heat Control Knob

The HEAT control knob (6) is located on the left side of front console to the left of the steering column. The knob is a push-pull control that positions a flow diverter valve in the hot water heater supply line. Pull out on the knob (PULL ON) to allow hot water to flow through the heater coil and push in on the knob (PUSH OFF) to shut off the flow of hot water to the coil.

Fan Control Switch

The FAN control switch (7) is located on the left side of the front console. The switch is a four-position rotary switch (OFF, LOW, MED, HIGH) that controls operation of the heater or air conditioning blower to circulate heated or cool air throughout the cab.

Park Brake Control Switch

The PARK BRAKE control switch (8) is located on the left side of the front console. This two-position rocker switch (ON/OFF) is used to apply and release the parking brake on the transmission. The red square LED on the switch is illuminated when the pressure switch in the brake release system is activated and the brake is applied. The switch has a lock to prevent accidental activation.

Air Conditioner Control Switch (Optional)

The air conditioner (AIR COND) control switch (9) is located on the left side of the front console. The switch is a twoposition rocker switch (OFF, ON) that controls the operation of the optional air conditioning system in conjunction with the FAN switch. When the switch is in the ON position, the square amber LED on the switch is illuminated.
