Page 17: Maintenance
Maintenance This section contains instructions for performing the inspection, lubrication, and maintenance proce- dures required to maintain the compressor in proper operating condition. The importance of per- forming the maintenance described herein cannot be over emphasized. The periodic maintenance procedures to be performed on the equipment covered by this manual are listed on the following page. -
Page 18: Maintenance Schedule
. r a r i a . r e Use only Auto Crane’s synthetic compressor oil. The use of any other oil causes excessive carbon buildup, and may void the warranty on the compressor. NOTE 1. Under normal operating conditions, oil changes are required every 3 months. When operating in a dirty environment, change the oil and air filter more frequently as your particular operating conditions dictate. -
Page 19: Lubrication Recommendation
Auto Crane Piston lubricant. The lubricant supplier’s recommendation must, therefore, be based upon not only the following general characteristics, but also upon his own knowledge of the suitability of the recommended lubricant in piston air compressors operating in the particular environment involved. -
Page 20: Compressor Oil
Maintenance 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. No lubricant, however good and/or expensive, can replace proper maintenance and attention. -
Page 21: Hydraulic Oil Cooler
Maintenance HYDRAULIC OIL COOLER The interior of the oil cooler should be cleaned when the pressure drop across it at full flow exceeds 25 PSI. Remove cooler. 2. Circulate a suitable solvent to dissolve and remove varnish and sludge. 3. Flush generously with hydraulic oil. 4. -
