Machine Controls
(fig. 5-1)
There are three primary machine controls: lift arm con-
trol (1), drive control (2) and throttle (3).
Lift Arm Control
The lift arm control (1) is a pilot operated joystick that
allows the operator to raise or lower the lift arms and
dump or curl the quick attach mechanism.
Drive Control
The drive control (2) is also a pilot operated joystick. It
allows the operator to change the direction and speed
of the machine.
Throttle
The foot throttle (3) controls engine rpm.
Instrumentation
The Instruments (Figure 5-2) are positioned in the lap
bar for good visibility and when seated inside the oper-
ator enclosure. Instruments include the following com-
ponents.
(1)
Engine Temperature Gauge
(2)
Multi-Gauge
• Oil Pressure Gauge
• Hyd. Oil Temperature Gauge
• Fuel Gauge
• Voltmeter
(3)
Tachometer
(4)
Indicator Light Display
• High Range Indicator
• Low Range Indicator
• Glow Plug Operation Indicator
• Parking Brake Indicator
NOTICE
If the engine coolant temperature, engine oil pressure or
hydraulic oil temperature gauges read above normal (or
below normal for engine oil pressure) during normal machine
operation, shut the machine down immediately. Diagnose the
problem and make any necessaryrepairs before continuing to
operate the machine.
NOTICE
If the battery low-voltage light illuminates, drive the machine
to a suitable location and shut the engine off. Diagnose the
problem and make needed repairs before continuing to oper-
ate.
The glow plug operation light illuminates only when the
key switch is turned to engine pre-heat, showing nor-
mal operation.
