Instrument Panel; Engine Oil Pressure Gauge; Engine Coolant Temperature Gauge; Compressor Discharge Pressure Gauge - Boss 210 DUS JD4045 Service And Maintenance Manual

5.16 Instrument Panel

The 210 DUS Air Compressor incorporates an instrument panel that includes numerous gauges and
controls in a single, easy to access location.
I. Engine Oil Pressure Gauge
This feature displays the oil pressure inside the engine block. When the pressure drops below 20
PSI, the system will shut down. During operation, the engine oil pressure should be approximately
60 PSI to 80 PSI.
II. Engine Coolant Temperature Gauge
This feature displays the temperature of the engine coolant. When the temperature reaches 235°F,
the system will shut down. During operation, the temperature should be approximately 190°F to
210°F.
III. Compressor Discharge Pressure Gauge
This feature displays the pressure downstream of the airend.
IV. Compressor Discharge Temperature Gauge
This feature displays the compressor discharge temperature. When the temperature reaches 245°F,
the system will shut down. During operation, the discharge temperature should be approximately
170°F to 190°F.
V. Hourmeter
The hourmeter records the total number of operating hours. It serves as a guide in following the
recommended maintenance schedule. The hourmeter will only run when the engine is operating.
VI.

Voltmeter

This feature displays the voltage of the battery. The voltmeter will display when the ignition switch is
in the "RUN" position. During operation, the voltmeter should be approximately 14 VDC.
VII.

Unloader Valve

This turn valve is used to limit the compressor system pressure. When the valve is in the loaded
position, the system will build to the regulator setting. If the valve is set to unloaded, the system will
build to approximately 45 PSI.
VIII.

Emergency Stop Switch

The system is equipped with an emergency stop switch to immediately shutdown the machine.
IX.

Bypass Switch

The bypass switch will temporarily disable the engine oil pressure shutdown during startup.
X.

Ignition Switch

The ignition switch is used for starting and stopping the machine.
