Safety
Safety procedures while servicing the compressor are
important to both the service personnel and to those who
may be around the compressor and the system it serves.
Listed below are some, but not all, procedures that should
be followed:
• Always check power supply disconnect. The Power-
on light may be inoperable.
• Wait for the unit to cool before starting service.
Temperatures may exceed at 350°F when the
compressor is working.
• Clean up fluid spills immediately to prevent slipping.
• Loosen, but do not remove, flange or component
bolting. Then, carefully pry apart same to be sure
there is no residual pressure before removing the
bolting.
• Never use a flammable solvent such as gasoline or
kerosene for cleaning air filters or compressor parts.
Safety solvents are available and should be used in
accordance with their instructions.
Unusual noise or vibration indicates a problem.
Do not operate the compressor until the source
has been identified and corrected.
Fluid Specifications
Each QSD
™
unit comes equipped with a fluid level sight
gauge, fluid fill opening, and a fluid drain located on the
gearbox.
QSD
™
compressors are factory filled with Quinsyn GL or
Quinsyn GLF (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
bearing performance. Consult Quincy Compressor
before changing brands or types of fluid.
Quinsyn GL or GLF synthetic fluid is available from any
authorized Quincy Distributor and is recommended for
use in all Quincy QSD
™
oil-free compressors. Failure to
follow this recommendation will adversely affect your
warranty.
Do not mix different grades or types of fluid. Do
not use inferior grades of fluids. Failure to follow
these recommendations may cause severe fluid
breakdown, resulting in the information of
varnish and sludge throughout the system. This
will result in clogging of the cooler and internal
fluid passages. Warranty will be voided.
