densed liquids.) If lubricant is contaminated, drain and replace.•Drain receiver tank, drop legs and traps in air distribution system.Receiver tanks subjected to freezing temperatures may contain ice.Store the compressor unit in a heated area before attempting to drainmoisture from the tank.•Give compressor an overall visual inspection and be sure safety guardsare in place.•Check for any unusual noise or vibration.•Check for lubricant leaks.•Check all pressurized components for rust, cracks or leaks. Immediatelydiscontinue use of the equipment and relieve all system pressureif any of these problems are discovered. Do not use the equipment untilit has been inspected and repaired by a qualified mechanic.Every 40 Hours (or Weekly)•<strong>Manual</strong>ly operate the pressure relief valves to be certain they areworking.•Clean the cooling surfaces of the intercooler, aftercooler and compressor.•Check the compressor for air leaks.•Check the compressed air distribution system for leaks.•Inspect lubricant for contamination & change if necessary.•Clean or replace the air intake filter. Check more often under humidor dirty conditions.Every 160 Hours (or Monthly)•Check belt tensionEvery 500 Hours (or Every 3 Months)•Change lubricant (more frequently in harsher environments).•Torque pulley clamp screws or jamnut.Every 1000 Hours (or Every 6 Months)•When Quin-Cip or Quin-Cip-D lubricant is used, lubricant changeintervals may be extended to every 1000 hours or every 6 months,whichever occurs first (change more frequently in harsher conditions).•Inspect compressor valves for leakage and/or carbon build-up. Ifexcessive sludge build-up exists inside the crankcase, clean the insideof the crankcase as well as the screen. Never use a flammable ortoxic solvent for cleaning. Always use a safety solvent andfollow the directions provided.Every 2000 Hours (or Every 12 Months)•Inspect the pressure switch diaphragm and contacts. Inspect thecontact points in the motor / starter.Servicing Reed ValvesQT & PLT Series compressor valve plates and reed valves should be inspectedand cleaned on a regular basis. The reed valves are made of stainless steel andcan be cleaned with a stiff bristle brush(not a wire brush!). A clean safetysolvent may also be used to loosen carbon deposits on the valve plates and reedvalves. Handle all parts with care; do not bend, mar or scratch any sealingsurfaces.DANGER !Never use gasoline, thinners, or other flammable solutions to cleanvalves or related parts.QT & PLT SeriesQuincy Compressor50161-106, January 2009 28 3501 Wismann Lane, Quincy Ill. - 62305-3116
LubricationQT and PLT Series basic compressors and units are normallyshipped from the factory with break-in lubricant in the crankcase.Before starting your compressor, check the lubricant level in thecrankcase. The lubricant level of QT-5, PLT-5, QT-7.5, PLT-7.5, QT-10and PLT-10 compressors must be kept at the top of the sightglass. Thelubricant level of QT-15, PLT-15, QT-30 & QT-54 compressors mustregister between the high and low marks on the dipstick. Replace thebreak-in lubricant after 100 hours of operation with Quin-Ciplubricant - use Quin-Cip-D in Xtreme models.Quin-Cip and Quin-Cip-D lubricants have proven under extensivetesting to minimize friction and wear, limit lubricant carryover, andreduce carbon and varnish deposits. They will support the performancecharacteristics and life designed into all Quincy compressorsand are highly recommended. Refer to the charts below to determinethe correct amount of lubricant and viscosity to use for your model andapplication.Approximate Crankcase Lubricant CapacitiesBasic Compressor ModelQT-5 & PLT-5 (incl.
