Lubrication

Each unit comes equipped with a fluid level sight gauge, fluid fill opening, and a fluid drain located in
the reservoir. The fill plug is drilled to allow some pressure to escape before the plug is
completely removed. Should you hear pressurized air venting through this hole, immediately
screw the plug back in to the reservoir. Relieve the pressure before proceeding.
Each unit is factory filled with QuinSyn IV synthetic fluid or QuinSyn F (food grade) synthetic fluid. The
use of other brands or types of fluid may reduce the design life of the compressor or cause problems
with filtration or carryover. Consult the Quincy factory before changing brands of fluid.
Hot fluid under pressure could cause death or serious injury. Do not
remove the fluid fill plug and attempt to add fluid to the air/fluid reservoir
while the compressor is in operation or when the system is under pressure.
Be sure that the compressor's red mushroom stop button is pushed in and
locked, and that the main power disconnect switch is in the off position and
locked out to assure that the compressor will not start automatically or by
accident.

Fluid Specifications

We recommend that all Quincy gear drive rotary screw compressors be filled with QuinSyn IV or QuinSyn
synthetic fluid. QuinSyn IV or QuinSyn is available from any authorized Quincy distributor. For
applications requiring a food grade fluid, we recommend QuinSyn F. Sustained (3 hours or more) of
discharge temperatures over 210
Failure to follow the above recommendation will adversely affect your warranty.

Fluid Life

QuinSyn IV fluid can be used up to 4,000 hours depending upon application and recommendations from
the fluid analysis. QuinSyn fluid can be used up to 8000 hours; QuinSyn F (food grade) can be used
between 2,000 and 3,000 hours under good operating conditions. Draining of the fluid should be done
while the fluid is hot to carry away more impurities. It is strongly suggested that a reputable fluid
analysis program be followed to establish fluid change intervals.
A free service provided with the use of QuinSyn IV fluid is a fluid analysis. This analysis provides the end
user with important information regarding the performance of the fluid and in detecting any special
problems that might arise. Fluid samples should be taken at the time of fluid filter changes or at 1,000-
hour intervals or sample as directed by analysis report. Fluid sample bottles, labels and instructions are
provided with the compressor package at the time of shipment. Additional sample bottles may be
purchased through your distributor.
