OPERATING CONTROLS AND PROCEDURES
Headlights Switch
The HEADLIGHTS switch (17) is located on the left side of
the front console. This two-position rocker switch (ON/OFF)
controls operation of the instrument lights, switch LED's, and
the headlights on the front of the crane. When the switch is in
the ON position, the square amber LED on the switch is
illuminated.
Boom Lights Switch (Optional)
The BOOM LIGHTS switch (optional) (18) is located on the
left side of the front console. This two-position rocker switch
(ON/OFF) controls operation of the boom flood lights. When
the switch is in the ON position, the square amber LED on
the switch is illuminated.
Hazard Lights Switch
The HAZARD lights switch (19) is located on the left side of
the front console. The switch is a two-position rocker switch
(ON/OFF) that causes the four turn signal lights and two
turnsignal indicator lamps to flash at the same time when the
switch is positioned to ON. When the switch is positioned to
ON, the square amber LED on the switch is also illuminated.
Hose Reel Brake On Indicator
The HOSE REEL BRAKE ON indicator (20) is located on the
lower section of the console. It illuminates red when the
HOSE REEL BRAKE is applied and the telescope control
foot pedal is in neutral.
NOTE: Do not telescope boom in or out when indicator
light is on and the telescope control foot pedal is
depressed.
Fuel Gauge
The fuel (FUEL) gauge (21) is located in the center of the
front console. The gauge indicates the quantity of fuel in the
fuel tank and has a scale calibrated from zero [0] to 4/4. The
fuel gauge receives a signal from a sending unit in the fuel
tank.
Engine Diagnostics Switches
Two ENGINE DIAGNOSTICS switches (the Test Mode
switch and the Idle switch) are located in the center of the
front console.
Test Mode Switch
The TEST MODE switch (22) is used when servicing the
engines electronic control system. It is a two position on/off
toggle switch used to activate the testing mode (fault codes).
When the test mode switch is on and is used in conjunction
with the idle (+/-) switch, access will be gained to toggle up
and down through the fault codes.
3-6
Idle Switch
The IDLE switch (23) is a two position (+/-) momentary
rocker switch that provides idle-control inputs that increases
and decreases the engine idle (when the test mode switch is
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 discon-
nect power from the crane functions controlled by the
hydraulic remote controllers on the armrests. Positioning
the switch to OFF prevents inadvertent operation of func-
tions due to bumping the controllers while roading or any
other operation. When the red LED switch is in the ON
position, the red LED square will be illuminated and the
crane function solenoid will be energized allowing crane
functions controlled by the hydraulic remote controllers
to be performed.
NOTE: The seat switch must be activated and the LH
armrest must be in the down position before the
crane function solenoid may be energized.
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
has two placarded positions, EXTEND and RETRACT, and
is used in conjunction with the switches on the outrigger
selector switches (15) to control the operation of the
stabilizer and extension cylinders. After positioning the
outrigger selector switch, 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.
