OPERATING CONTROLS AND PROCEDURES
in the OFF position) or diagnostic mode fault codes (when the test mode switch is in the ON position).
Engine Coolant Temperature Gauge The engine coolant temperature (WATER TEMP) gauge (24) is located in the center of the front console. The gauge indicates the engine coolant temperature on a dual scale calibrated from 38 to 138°C and 100 to 280°F. The gauge receives a signal from the engine ECM and a temperature sending unit in the engine cooling system.
Tachometer The tachometer (25) is located in the center of the front console. The tachometer registers engine rpm and is calibrated in rpm x 100 with a range of zero [0] to 35. The tachometer receives a signal from the engine ECM.
Crane Function Power Switch The CRANE FUNCTION power switch (26) is located on the right side of the front console. This two-position (ON/OFF) rocker switch permits the operator to disconnect power from the crane functions controlled by the hydraulic remote controllers on the armrests. Positioning the switch to OFF prevents inadvertent operation of functions due to bumping the controllers while roading or any other operation. With the switch in the OFF position, operation of hydraulic boost and high speed hoist is also prevented. When the switch is in the ON position, the red LED square in the switch will be illuminated and the crane function solenoid will be energized allowing crane functions controlled by the hydraulic remote controllers to be performed.
Outriggers Extend/Retract Switch The OUTRIGGERS EXTEND/RETRACT switch (27) is located on the top right of the front console. The switch is a three-position, spring centered to off rocker switch. It has two placarded positions, EXTEND and RETRACT, and is used in conjunction with the switches on the outrigger selector panel to control the operation of the stabilizer and extension cylinders. After positioning the switch on the outrigger selector panel, positioning the OUTRIGGER Extend/Retract switch to EXTEND or RETRACT energizes the control solenoid to allow hydraulic fluid to flow through the control solenoid valve and the individual solenoid valve to move the selected component in the selected direction.
Load Moment Indicating (LMI) and Work Area Definition System Control Panel The LMI and Work Area Definition System control panel (28) is located on the right side of the front console. It maintains the controls and indicators for the crane’s Load Moment Indicating (LMI) System and Work Area Definition System. Refer to the LMI Manual for detailed information.
Transmission Service Indicator The TRANSMISSION (XMSN) SERVICE indicator (29) is located on the front console on the indicator light display. It illuminates red during low transmission oil pressure or high transmission oil temperature conditions. A warning buzzer will also sound.
Low Brake Pressure Indicator The LOW BRAKE PRESSURE indicator (30) is located on the front console on the indicator light display. It illuminates red when the pressure in the dual accumulator charge valve falls below normal operating requirements. A warning buzzer will also sound.
Rear Steer Control Switch The REAR STEER control switch (31) is a three-position, spring centered to off, rocker switch, located on the left armrest. Positioning the switch to the right (R) actuates a control valve to turn the rear wheels to the left, causing the crane to turn to the right. Positioning the switch to the left (L) actuates a control valve to turn the rear wheels to the right, causing the crane to turn to the left. Releasing the switch allows it to spring return to the center off position.
Auxiliary Hoist Speed Selector Switch (Optional) The auxiliary hoist (AUX HOIST) rocker switch (32) is located on the left armrest. The auxiliary hoist switch must be in the ON position before the auxiliary hoist can be operated. Positioning this switch to OFF prevents the operator from accidentally activating the auxiliary hoist. With the switch in the ON position, the amber LED square in the switch will be illuminated.
Swing Control Lever (Single Axis Option) The SWING control lever (33), located on the left armrest, controls the swing function. The lever, when positioned forward (rotates the turntable clockwise) or back (rotates the turntable counterclockwise), actuates a control valve through hydraulic pilot pressure to provide 360 degree continuous rotation in the desired direction.
Swing And Telescope Or Swing and Auxiliary Hoist Control Lever (Dual Axis Option) The SWING and TELESCOPE or AUXILIARY HOIST (SWING/TELE or SWING/AUX) control lever (34) is located on the end of the left armrest. The lever controls the swing and telescope functions when the crane is not equipped with an auxiliary hoist. When equipped with an auxiliary hoist, the lever controls swing and auxiliary hoist functions and telescope functions are controlled through a foot pedal.
