•Give compressor an overall visual inspection and be sure
safety guards are in place.
•Check for any unusual noise or vibration.
•Check oil pressure
(hot)
. Maintain 18 to 20 PSIG*
•Check for oil leaks.
•Check all pressurized components for rust, cracks or leaks. Immedi-
ately 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 and compressor.
•Check the compressor for air leaks.
•Check the compressed air distribution system for leaks.
•Inspect oil 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 oil is used, oil 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 crank-
case, 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.
Lubrication
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 opera-
tion or 1 month (whichever comes first) with Quin-Cip lubricant!
Quin-Cip lubricant has proven under extensive testing to minimize friction
and wear, limit oil carryover, and reduce carbon and varnish deposits. It will
support the performance characteristics and life designed into all Quincy
compressors and is highly recommended.
Refer to the charts below to
determine the correct amount of lubricant and viscosity to use for your model
and application.
*High pressure rated compressors should maintain 22 to 25 PSIG of oil pressure.
