  • Page 26: Start-Up & Operation

    Remove all installation tools from the compressor and check for installation debris. Step 2) Unless otherwise specified, QP Series compressors are normally shipped with break-in lubri cant in the crankcase. Check the lubricant level in the crankcase. (Refer to SECTION 5, Lu- brication for quantity and types of lubricant to be used.)

  • Page 27: Initial Starting & Operating

    If there are any questions regarding any part of the instructions, please call your local Quincy distributor, or the Quincy Compressor factory. CAUTION ! When using battery cables to start engine driven units do not use more than a total of 40 ft.

  • Page 28: Daily Starting Checklist

    Quincy Compressor recommends that a new or rebuilt reciprocating compres- sor should be run for a total of 100 hours at full discharge operating pressure to break-in the new piston rings. Until the rings are seated, the compressor will discharge higher than normal amounts of lubricant. In light of this fact, the lubricant level should be checked more frequently during the 100 hour break-in period.
