Section VI - Compressor Fluids
Lubrication
QSI model air compressors use pressure
differential to circulate the fl uid. Positive
pressure maintained in the reservoir forces
the fl uid throughout the machine.
Each Quincy compressor is fi lled at the
factory with the correct amount of one
of the synthetic fl uid listed in the Fluid
Specifi cations.
The use of other brands or types of
fl uid may reduce the design life of the
compressor or cause problems with
fi ltration or carryover. Consult the Quincy
Service Department before changing
brands of fl uid.
Fluid Level
Fluid level is monitored by a sightglass
while in operation. Fluid level should
completely fi ll the sight gauge. DO NOT
OVERFILL.
Each unit comes equipped with a fl uid level
sight gauge, fl uid fi ll opening, and a fl uid
drain in the reservoir. The fi ll plug is drilled
to allow some pressure to escape before
the plug is completely removed. Should
you hear pressurized air venting through
the hole, immediately screw the plug back
into the reservoir. Relieve the pressure in
the machine before proceeding.
CAUTION!
Hot fluid under pressure could cause
death or serious injury. Do not remove
the fluid fill plug and attempt to
add fluid to the 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.
