Brake Failure Lamp:

The front and rear brakes are on

independent brake line systems. If during normal oper-
ation with the brake pedal depressed, a loss of pressure
occurs in either system, the brake failure lamp comes
on.

Failure in one line of the system does not affect the
operation of the other system line. However, the

MANDATORY SAFETY SHUTDOWN PROCE-
DURE (p.10)

should be followed and required repairs

made immediately.

During normal operation the lamp should remain off.

Engine Oil Pressure Lamp:

Indicates whether suffi-

cient engine lubricating oil pressure is present or not.
During normal operation, with the engine running, this
lamp should be off. During starting and when the
engine is not running, this lamp will be on.

IMPORTANT:

If this lamp comes on during nor-

mal operation with the engine running, stop the
engine immediately. After allowing the oil to drain
down for a few minutes, check the engine oil
level. Maintain oil level at the FULL mark on the
dipstick

Hourmeter:

Indicates the operating time of the

machine and should be used for keeping up the main-
tenance log.

Coolant Temperature Gauge:

Indicates the tempera-

ture of the engine coolant. Under normal conditions,
this gauge should indicate approximately 185

(85

Fuel Level Gauge:

Indicates the amount of fuel

remaining in the fuel tank.

Hydraulic Pressure Test Ports:

A test gauge can be

inserted to check main or steering system pressures.

Boom Load Capacity:

A series of flip charts show lift

height and reach limits relative to the load weight
being handled with various attachment tools.

Switch Panel

Clutch Cutout Function:

When activated, it allows

greater engine acceleration and power to the hydraulics
system without power to the drive axles while the ser-
vice brake pedal is depressed.

DASH AREA

Start Keyswitch OFF:

When the key is vertical in the

keyswitch, power from the battery is disconnected to
the control and instrument panel electrical circuits.
Also, this is the only position in which the key can be
inserted or removed.

Start Keyswitch ON:

When the key is turned one

position clockwise from the vertical (OFF) position,
power from the battery is supplied to all control and
instrument panel electrical circuits.

NOTE:

If the engine requires repeated attempts

to start, the key MUST be returned to the OFF
position between starting attempts to prevent bat-
tery run down.

Start Pushbutton:

With keyswitch in ON position,

depress the button to activate the starter. Release it as
soon as the engine starts.

Circuit Breaker:

The left 15 amp breaker protects

dash and engine electrical circuits. If it is not in the
depressed position, the gauges and indicators on the
dash will not work and the engine will shut off.. The
right 15 amp breaker protects the reserve brake system.

Horn Push Button:

With the keyswitch ON, depress

the horn button to activate warning sound.

Park Brake ON:

A buzzer located behind the dash

sounds as long as the park brake lever is engaged, and
the transmission is in forward or reverse.

Transmission Oil Temperature:

This lamp indicates

whether the transmission oil is at the proper tempera-
ture or not. During normal operation this lamp should
be off indicating that the transmission oil system is at
the proper temperature.

IMPORTANT:

If this lamp comes on during nor-

mal operation, a problem may exist in the trans-
mission oil system. Stop the machine immediate-
ly and investigate the cause of the problem!

Alternator Lamp:

Indicates the condition of the elec-

trical charging system. During normal operation, this
lamp should be off. If the charge rate is too high or too
low, this lamp will come on.
