Step 12) After all the above conditions have been satisfied, the unit can be
connected to the proper power source.
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.
Initial Starting & Operating
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 com-
pressor. 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.
Oil pressure should be maintained at 18 to 20 PSIG after 20 minutes
of run time. Normally the oil pressure does not need to be adjusted. But
if it does, loosen the locknut on the adjustment screw located on the right
side of the oil pump housing (see Fig. 4-1, Oil Pressure Adjustment ).
Increase the oil pressure by turning the adjustment screw clockwise; de-
crease the oil pressure by turn ing the adjusting screw counterclockwise.
After adjustment tighten the locknut.
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 oper-
ate the compressor for at least one hour. Shut the compressor off and follow
precautions outlined in SECTION 5, Stopping for Maintenance . Retorque
the cylinder to head capscrews to the specifications outlined in the parts book
corresponding to the Record of Change for your compressor after the compres-
sor has cooled.
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.
