Maintenance - Quincy QTS Series Instruction Manual

Step 6)New compressors should be run with ap-
proximately 80 PSI of air pressure in the
tank for 1 hour to break-in (use tank drain or
regulator to control tank pressure). This will
allow the compressor time to warm up and
seat the rings.
Step 7)To stop the compressor, flip the toggle on the
pilot valve to the "MANUAL UNLOAD" posi-
tion and carefully unplug the power cord
from the power source or shut the engine off.
Start / Stop and Dual Control Models
Step 1)Flip the contact lever on the side of the
pressure switch to the "OFF" position (see
Fig. 13).

Step 2)Plug the power cord into a properly grounded
and rated power source.
Step 3)Start the compressor by flipping the contact
lever on the side of the pressure switch to the
"AUTO" position.
Step 4)At initial start-up, verify that the compressor
flywheel is rotating counterclockwise (as
viewed from the flywheel side of compres-
sor). Watch and listen for excessive vibration
and unusal noise. If either exist, stop the
compressor and refer to TROUBLESHOOT-
ING.
Step 5)New compressors should be run with the
tank drain valve open for 1 hour to break-in
the compressor. This will allow the compres-
sor time to warm up and seat the rings.
Step 6)To stop the compressor, flip the contact lever
on the side of the pressure switch to the
"OFF" position. Carefully unplug the power
cord from the power source.
Retorque Cylinder to Head Capscrews
for Optimal Performance
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 perfor-
mance, Quincy recommends that you initially oper-
ate the compressor for at least one hour. Then shut
the compressor off and allow it to cool. Follow the
precautions outlined in MAINTENANCE. Retorque
the cylinder to head capscrews to the specifications
indicated in the parts book that corresponds to the
Record of Change for your compressor after the
compressor has cooled.

MAINTENANCE

The following procedures should be performed when
stopping the compressor for maintenance or service:
Step 1)Per OSHA regulation 1910.147, disconnect
Pressure Switch
Step 2)Completely relieve the system of air pressure
Step 3)Open all manual drain valves within the area
Step 4)Wait for the unit to cool before starting to
Maintenance Schedule
Refer to the gas engine owner's manual for mainte-
nance procedures to be performed on the engine. If
the unit is used in an excessively dirty or dusty
environment, check and perform all maintenance
procedures more often.

(whichever occurs first)
• Replace break-in lubricant with Quin-Cip (Refer

and lockout/tagout the main power source.
Then, isolate the compressed air supply by
closing and locking out a manual shutoff
valve upstream and downstream from the
compressor. Display a sign in clear view at
the main power source and at the shutoff
valve stating that the compressor is being
serviced.
