INSTRUMENTATION
The BOSS INDUSTRIES hydraulic drive compressor unit incorporates a gauge panel that monitors
temperature, pressure and hours of operation.
HOURMETER
The hourmeter records the total number of operating hours. It serves as a guide in following the
recommended inspection and maintenance schedule. The hourmeter will only run when there is pressure
in the system.
COMPRESSOR DISCHARGE AIR/OIL TEMPERATURE SWITCHGAUGE
This switchgauge indicates compressor air discharge temperature. The switchgauge ensures safety
shutdown in case of excessive operating temperatures, preventing compressor damage, by stopping
hydraulic flow to the compressor motor.
