Machine Controls
(fig. 4-1)
There are three primary machine controls: lift arm con-
trol (2), drive control (1) and throttle (3).
Lift Arm Control
The lift arm control (2) is a pilot operated joystick that
allows the operator to raise or lower the loader and
dump or curl the quick attach mechanism.
Drive Control
The drive control (1) is also a pilot operated joystick. It
allows the operator to change the direction and speed
of the machine.
Throttle
The hand throttle (3) controls engine rpm.
Instrumentation
The Instruments (Figure 4-2) are positioned in the
overhead dash panel for ease of access and visibility
when seated inside the operator enclosure.
Instruments include the following components.
(1)
Fuel Gauge
(2)
Tachometer (optional)
(3)
Engine Coolant Temp. Gauge (optional)
(4)
Hour Meter
(5)
Warning Indicator Display
• Engine Oil Pressure Warning Light
• Engine Temperature Warning Light
• Hydraulic Oil Temperature Warning Light
• Battery Voltage Warning Light
The glow plug operation light illuminates only when the
key switch is turned to engine pre-heat, showing nor-
mal operation.

If the engine temperature, engine oil pressure or
hydraulic oil temperature lights illuminate or should
the eng. coolant temp. gauge read excessive tempera-
tures during normal machine operation, shut the
machine down immediately (in a safe location).
Diagnose the problem and make any necessary
repairs before resuming normal operation.
NOTICE
If the battery low-voltage light should illuminate dur-
ing operation, drive the machine to a suitable location
and shut the engine off. Diagnose the problem and
make any needed repairs before resuming operation.
