Left Turn Signal Indicator (25). The indicator is located on the upper left of the front
console panel. The indicator lights when the turn signal lever is positioned down to make a
left turn.
SWING BRAKE ON Indicator (26). The indicator is located on the upper left side of the
front console panel. The red indicator is lit when the SWING BRAKE ON/OFF Selector
Switch (18) is in ON position. The indicator is controlled by the position of the SWING
BRAKE ON/OFF Selector Switch (18).
TELESCOPE ENGAGED Indicator (27). The indicator is located on the upper left side of
the front console panel. The green indicator is lit when the telescope function is controllable
via the Telescope/Clamshell Control Pedal (21) as selected by the TELE/CLAMSHELL
Selector Switch (10) on the left arm rest.
CLAMSHELL/GRAPPLE ENGAGED Indicator (28). The indicator is located on the upper
middle of the front console panel. The green indicator is lit when the clamshell/grapple
function is controllable via the Telescope/Clamshell Control Pedal (21) as selected by the
TELE/CLAMSHELL Selector Switch (10) on the left arm rest.
DIFFerential LOCKED Indicator (29). The indicator is located on the upper middle portion
of the front console panel. The red indicator lights when the DIFFERENTIAL LOCK Switch
(33) is in the LOCKED position and the front and rear differentials are locked.
panel. The tachometer registers engine RPM and is calibrated in RPM x 100 with a range
of 0 to 40. It receives a signal from a sending unit on the engine.
(30) and registers total hours of engine operation.
With the IGNITION Switch (56) in the ON position and before starting the engine, the
voltmeter indicates the condition of the batteries. With the engine running, it indicates
output voltage of the alternator. The voltmeter indicates voltage on a scale from 20 to 32
volts.
DIFFERENTIAL LOCK Switch (33). The switch is a two-position toggle switch located on
the lower left side of the front console panel. Placing the switch to the LOCKED position
activates two solenoid valves to route air pressure to lock the front and rear differentials.
The differentials will lock only in the four-wheel drive mode. With the differentials locked,
the right and left wheels on each axle rotate at the same rate. When used with the DRIVE
AXLE Selector Switch in 4WD position, torque is equally distributed to the front and rear
axles driving all wheels at the same rate. Placing the switch to the UNLOCKED position,
returns the axles to the normal mode.
Engine OIL PRESSure Gauge (34). The gauge is located on the left side of the front
console panel. The gauge indicates the engine oil pressure on the dual scale graduated
from 0 to 100 psi and 0 to 690 kPa. Normal indication at idle is 10 psi (70 kPa), at high idle
is 35 psi (241 kPa), and at maximum governed speed is 85 psi (686 kPa). It receives a
signal from an oil pressure sending unit on the engine.
