Daily Starting Checklistwitnessed, stop the compressor and correct the problem. After two days ofoperation check belt tension, lubricant level, and inspect the system for leaks.A new or rebuilt reciprocating compressor should be run for a total of 100hours at full discharge operating pressure to break-in the new piston rings.Until the rings are seated, the compressor will discharge higher than normalamounts of lubricant. In light of this fact, the lubricant level should be checkedmore 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 thoroughly understood."MANUALUNLOAD"positionStep 1)Step 2)Step 3)Check lubricant level in crankcase.Drain liquid from the air receiver and moisture trap (if so equipped).Jog the starter button and check compressor rotation (refer toSteps 14 & 15 of Pre-Starting Checklist).Note: Continuous Run Units - Prior to starting a continuous rununit, flip the toggle lever on the pilot valve stem to the “<strong>Manual</strong>Unload” position (see Fig. 4-2). Now the compressor can be startedunloaded. Once the compressor is running at full speed, flip thetoggle lever back to the “RUN” position."RUN"positionStep 4) Start compressor per factory instructions. (Refer to SECTION 4,Pre-Starting Checklist and Initial Starting & Operating.)Step 5)Check system pressure.Fig. 4-2Continuous RunPilot ValveThe following steps apply to QT & PLT compressors as well as XtremeUnits. On Xtreme Units, remove the front door to complete Steps 6-9.After start-up, replace the door and secure the quarter turn latches.Step 6)Step 7)Step 8)Step 9)Check cooling fan.Check all pressure relief valves for proper operation.Check control system for proper operation.Check the lubricant level in the crankcase several minutes afterthe compressor has run. (Discoloration or a higher lubricant levelreading may indicate the presence of condensed liquids.) If lubricantis contaminated, drain and replace.QT & PLT SeriesQuincy Compressor50161-106, January 2009 26 3501 Wismann Lane, Quincy Ill. - 62305-3116
SECTION 5MAINTENANCE & LUBRICATIONStopping for MaintenanceThe following procedures should be followed when stopping the compressor formaintenance or service:Step 1)Per OSHA regulation 1910.147: The Control of Hazardous EnergySource (Lockout/Tagout), disconnect and lockout the main powersource. Display a sign in clear view at the main power switchstating that the compressor is being serviced.WARNING !Never assume a compressor is safe to work on just because it is notoperating. It could restart at any time.Step 2)Step 3)Step 4)Step 5)Isolate the compressor from the compressed air supply by closinga manual shutoff valve upstream and downstream from the compressor.Display a sign in clear view at the shutoff valve stating thatthe compressor is being serviced.Lock open a pressure relief valve within the pressurized system toallow the system to be completely de-pressurized. NEVER removea plug to relieve the pressure!Open all manual drain valves within the area to be serviced.Wait for the unit to cool before starting to service. (Temperaturesof 125°F can burn skin. Some surface temperatures exceed 350°Fwhen the compressor is operating.)Maintenance ScheduleTo assure maximum performance and service life of your compressor, a routinemaintenance schedule should be developed. A sample schedule has beenincluded here to help you to develop a maintenance schedule designed for yourparticular application. Time frames may need to be shortened in harsherenvironments.At the back of this instruction manual you will find a MaintenanceSchedule Checklist. Make copies of this checklist and retain the master tomake more copies as needed. On a copy of the checklist, enter dates and initialsin the appropriate spaces. Keep the checklist and this Instruction <strong>Manual</strong>readily available near the compressor.Maintenance Schedule Checklist SampleEvery 8 Hours (or Daily)•QT-5, PLT-5, QT-7.5, PLT-7.5, QT-10, PLT-10 and Xtreme lubricantlevels should be kept at the top of the sight glass.•Maintain lubricant levels of QT-15, PLT-15, QT-30 & QT-54 modelsbetween high and low level marks on dipstick. Check the lubricantlevel several minutes after the compressor has run.
