INSTRUMENTS AND CONTROLS
GAUGES AND LIGHTS
Gauge and Light Cluster
Note: Gauges and indicator lights operate only when
the ignition switch is in the ON position.
(1) Boom/Transfer Extend Lock—Red lamp lights
to show when boom extend and transfer extend
functions are locked out because the outriggers
are not down. See “Stability Systems” on
page 32.
(2) Park Brake—Red lamp lights to show when park
brake is applied and goes out when park brake is
released. See “Park Brake Control” on page 14.
(3) Check Engine—Red lamp lights and buzzer
sounds for 30 seconds before engine shuts down
when a “Shutdown” fault is detected. Under
normal conditions, the light and buzzer will go out
quickly after engine start. If the light or buzzer
does not go out or comes on during vehicle
operation, shut off engine immediately,
investigate, and repair before operating.
(4) Engine Water Temperature—Registers from
100 to 240 °F. Normal operating temperature is
180 to 185 °F.
(5) Fuel Level—Shows fuel level in fuel tank.
(6) Rear Oscillation Lock—The rear oscillation lock
light will come on when the boom angle is above
20°. See “Stability Systems” on page 32.
(7) Low Brake Pressure—Red lamp lights and
buzzer sounds when service brake hydraulic
system pressure drops below the safe operating
level. Under normal conditions, the light and
buzzer will go out quickly after engine start. If the
light or buzzer does not go out or comes on
during vehicle operation, shut off engine
immediately, investigate, and repair before
operating. Do not operate vehicle when low
brake pressure light or buzzer is on.
(8) Transmission Declutch—Red lamp lights to
show when transmission declutch feature is
active. See “Transmission Declutch Switch” on
page 16.
(9) Engine Oil Pressure—Shows operating engine
oil pressure. Gauge registers from 0 to 80 PSI.
Normal operating pressure is 50 to 60 PSI.
(10)Voltmeter—Indicates system voltage. Gauge
registers from 10 to 16 volts. Normal operating
voltage range is 14.5 to 15 volts. With ignition in
ON position and engine off, battery voltage is
indicated. This should normally be 12.6 volts.
Transmission Oil Temperature Gauge
(11)Transmission Oil Temperature—Located on
the instrument panel to the left of the Gauge and
Light Cluster. Registers from 140 to 320 °F with
Celsius equivalents. If the temperature rises
above 230 °F (110 °C) stop the vehicle
immediately, shift to neutral and run the engine at
half throttle. The temperature should drop
quickly. If the temperature does not drop, shut off
engine and investigate.
