Page 11: Compressor Terminology
COMPRESSOR TERMINOLOGY AIR/OIL COALESCER - Performs second stage separation of oil from compressed air feeding air tools. Sometimes referred to as the separator element. CFM - Refers to the volume of compressed air being produced, expressed as cubic feet of air per minute. -
Page 12: Description Of Components
DESCRIPTION OF COMPONENTS COMPRESSOR ASSEMBLY The AUTO CRANE hydraulic drive compressor assembly is a positive displacement, oil flooded, rotary screw type unit employing one stage of compression to achieve the desired pressure. Components include a housing (stator), two screws (rotors), bearings, and bearing supports. - Page 13 DESCRIPTION OF COMPONENTS SAFETY VALVE The pop safety valve is set at 200 PSI and is located at the top of the air/oil sump. This valve acts as a backup to protect the system from excessive pressure that might result from a malfunction. AIR/OIL COALESCER The coalescer is self-contained within a spin-on housing.
- Page 14 DESCRIPTION OF COMPONENTS INSTRUMENTATION The AUTO CRANE 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.
- Page 15 DESCRIPTION OF COMPONENTS AUTOMATIC BLOW DOWN VALVE There is one blow down valve in the compressor system. It is located at the intake valve and will automatically bleed the sump to zero pressure when the compressor is disengaged. Blow down time interval takes between 45 and 60 seconds.

Page 16: Inspection, Lubrication, And Maintenance
INSPECTION, LUBRICATION, AND MAINTENANCE This section contains instructions for performing the inspection, lubrication, and maintenance procedures required to maintain the compressor in proper operating condition. The importance of performing the maintenance described herein cannot be over emphasized. The periodic maintenance procedures to be performed on the equipment covered by this manual are listed below. - Page 17 LUBRICATION AND MAINTENANCE CHART N " " L l i f . l i t l i t t i t l i t l i NOTE: Compressor oil and filter is to be changed after the first 50 hours of operation. After this, normal intervals are to be followed.

- Page 19 DUE TO ENVIRONMENTAL FACTORS THE USEFUL LIFE OF ALL “EXTENDED LIFE” LUBRICANTS MAY BE SHORTER THAN QUOTED BY THE LUBRICANT SUPPLIER. AUTO CRANE ENCOURAGES THE USER TO CLOSELY MONITOR THE LUBRICANT CONDITION AND TO PARTICIPATE IN AN OIL ANALYSIS PROGRAM WITH THE SUPPLIER.
- Page 20 MAINTENANCE If some of the maintenance intervals in the schedule outlined in this manual seem to be rather short, it should be considered that one hour’s operation of a compressor is equal to about 40 road miles on an engine. Thus, eight hours operation is equal to 320 road miles, 250 hours is equal to 10,000 road miles, etc.

Page 24: Troubleshooting
TROUBLESHOOTING This section contains instructions for troubleshooting the equipment following a malfunction. The troubleshooting procedures to be performed on the equipment are listed below. Each symptom of trouble for a component or system is followed by a list of probable causes of the trouble and suggested procedures to be followed to identify the cause. - Page 25 TROUBLESHOOTING IMPROPER DISCHARGE PRESSURE 1. If discharge pressure is too low, check the following: A. Too much air demand. (Air tools require more air than what the compressor can produce, air tools are free wheeling without resistance.) B. Service valve wide open to atmosphere. C.
- Page 26 TROUBLESHOOTING COALESCER PLUGGING If the coalescer element has to be replaced frequently because it is plugging up, it is an indication that foreign material may be entering the compressor inlet or the compressor oil is breaking down. Compressor oil can break down prematurely for a number or reasons. (1) Extreme operating temperature, (2) negligence in draining condensate from oil sump, (3) using the improper type of oil, (4) dirty oil, (5) oil return nozzle plugged.

Page 27: Compressor Operation
COMPRESSOR OPERATION Before starting the compressor, read this section thoroughly. Familiarize yourself with the controls and indicators, their purpose, location, and use. - Page 28 COMPRESSOR OPERATION OPERATING CONDITIONS The following conditions should exist for maximum performance of the compressor. The truck should be as close to level as possible when operating. The compressor will operate on a 15 degree sideward and lengthwise tilt without any adverse problems. Operation in ambient tempera- tures above 100°F (38°C) may experience high temperature shutdown.
