QT/QTS Series Quincy Compressor2022208700, September 2018 33Step 13) Jog the starter switch to check the rotational direction of thecompressor. It should agree with the rotation arrow embossed onthe compressor sheave.Step 14) Check for proper rotation of the cylinder cooling fan (fins insidesheave). The fan should blow cooling air across the cylinder.Initial Starting & OperatingThis instruction manual, as well as any instructions supplied by manufacturersof supporting equipment, should be read and understood prior to starting thecompressor. If there are any questions regarding any part of the instructions,please call your local Quincy distributor, or the Quincy Compressor factory.When using battery cables to start engine driven units do not usemore than a total of 40 ft. of #4 gauge cable (GND & HOT).With the pre-starting checklist completed and satisfied, start the compressor.Watch and listen for excessive vibration and strange noises. If either exist,stop the compressor. Refer to SECTION 6, Troubleshooting for help indetermining the cause of such problems.Check the air receiver pressure gauge or system pressure gauge for properreadings. If inadequate or excessive air pressure conditions exist, refer toSection 6 Troubleshooting.Heat created during the initial startup of a new compressor will cause slightexpansion of the head(s). This slight expansion crushes the head gasket ever soslightly and affects the torque value of the cylinder fasteners (capscrews). Toensure optimal performance, Quincy recommends that you initially operate thecompressor for at least one hour. Shut the compressor off and follow precautionsoutlined in SECTION 5, Stopping for Maintenance. Observe compressoroperation closely for the first hour of operation and then frequently for thenext seven hours. After the first eight hours, monitor the compressor at leastonce every eight hours. If any abnormal conditions are witnessed, stop thecompressor and correct the problem. After two days of operation check belttension, lubricant level, and inspect the system for leaks.Quincy Compressor recommends that a new or rebuilt reciprocatingcompressor should be run for a total of 100 hours at full discharge operatingpressure to break-in the new piston rings. Until the rings are seated, thecompressor will discharge higher than normal amounts of lubricant. In lightof this fact, the lubricant level should be checked more frequently during the100 hour break-in period.Daily Starting ChecklistDo not proceed until the Pre-starting Checklist and Initial Starting &Operating sub-sections have been read and are thoroughly understood.Step 1) Check lubricant level in crankcase.Step 2) Drain liquid from the air receiver and moisture trap (if so equipped).CAUTION !
