Step 13) Jog the starter switch to check the rotational direction of the
compressor. It should agree with the rotation arrow em bossed on
the compressor sheave.
Step 14) Check for proper rotation of the cylinder cooling fan (fins inside
sheave). The fan should blow cooling air across the cylinder.
This instruction manual, as well as any instructions supplied by manufacturers
of supporting equipment, should be read and un derstood prior to starting the
compressor. 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 use
more 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 in
determining the cause of such prob lems.
Check the air receiver pressure gauge or system pressure gauge for proper
readings. If inadequate or excessive air pressure conditions exist, refer to
Section 6 Troubleshooting.
Heat created during the initial startup of a new compressor will cause slight
expansion of the head(s). This slight expansion crushes the head gasket ever so
slightly and affects the torque value of the cylinder fasteners (capscrews). To
ensure optimal performance, Quincy recommends that you initially operate the
compressor for at least one hour. Shut the compressor off and follow precautions
outlined in SECTION 5, Stopping for Maintenance. Observe compressor
operation closely for the first hour of opera tion and then frequently for the
next seven hours. After the first eight hours, monitor the compressor at least
once every eight hours. If any abnormal conditions are witnessed, stop the
compressor and correct the problem. After two days of operation check belt
tension, lubricant level, and inspect the system for leaks.
Quincy Compressor recommends that a new or rebuilt reciprocating
compressor 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.
Do not proceed until the Pre-starting Checklist and Initial Starting &
Operating sub-sections have been read and are thor oughly understood.
Step 1) Check lubricant level in crankcase.
Step 2) Drain liquid from the air receiver and moisture trap (if so equipped).
