•Drain receiver tank, drop legs and traps in air distribution system.
•Give compressor an overall visual inspection and be sure safety guards
are in place.
•Check for any unusual noise or vibration.
•Check lubricant pressure (hot). Maintain 18 to 20 PSIG* .
•Check for lubricant leaks.
•Check all pressurized components for rust, cracks or leaks. Immediately
discontinue use of the equipment and relieve all system pressure if
any of these problems are discovered. Do not use the equipment until
it has been inspected and repaired by a qualified mechanic.
Every 40 Hours (or Weekly)
•Manually operate the pressure relief valves to be certain they are
working.
•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 humid
or dirty conditions.
Every 160 Hours (or Monthly)
•Check belt tension
Every 500 Hours (or Every 3 Months)
•Change oil & filter (more frequently in harsher environments).
•Torque pulley clamp screws or jamnut.
Every 1000 Hours (or Every 6 Months)
•When Quin-Cip lubricant is used, lubricant change intervals 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. The
oil sump strainer screen inside the crankcase of pressure lubricated
models should be thoroughly cleaned with a safety solvent during every
oil change. If excessive sludge build-up exists inside the crankcase,
clean the inside of the crankcase as well as the screen. Never use a
flammable or toxic solvent for cleaning. Always use a safety
solvent and follow the directions provided.
Every 2000 Hours (or Every 12 Months)
•Inspect the pressure switch diaphragm and contacts. Inspect the
contact points in the motor / starter.
QR-25 Series compressors are normally shipped with lubricant in the
crankcase. Before starting your compressor, check the lubricant level in the
crankcase. The lubricant should register between the high and low marks on
the dipstick. Replace the break-in lubricant after 100 hours of operation
or 1 month (whichever comes first) with Quin-Cip lubricant!
