Chapter Overview

This chapter contains an overview of the machine con-

trols and instrumentation. For further information

regarding machine controls, instrumentation or opera-

tion, refer to the operation and maintenance manual

for the PT-70/80. Included here are illustrations of the

following controls and instrumentation components and

a description of their functions.

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

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.

If the voltmeter reads less than 12 volts with the machine

running, drive the machine to a suitable location and shut the

engine off. Diagnose the problem and make needed repairs

before continuing to operate.

The glow plug operation light illuminates only when the

key switch is turned to engine pre-heat, showing nor-

mal operation.
