may also be used. For ambient tempera-
tures between 32˚ and 55˚ F, use ISO68
(SAE20W20) oil. Add oil only through the
oil fill plug. Pouring oil into any other ori-
fice will cause oil to leak and spray out
during operation. Fill to the center of the
sight gauge (See Figure 4).

Use of automotive
engine oil will
cause carbon deposits to build up on
the valves. This will shorten the life
expectancy and will require more fre-
quent service to the valves. Do not use
ATF hydraulic fluid, two-cycle oil or any
oil treatment product. Do not use
diester synthetic oil.
RECOMMENDED BREAK-IN PERIOD
The compressor should be run continu-
ously for one hour to allow proper
seating of the piston rings.
1. Open drain cock completely and run
the compressor for 60 minutes (See
Figure 5).
2. Turn off the compressor and close
drain cock. The compressor is now
ready for use.
Figure 5 - Opening Drain Cock
If the compressor is run under humid
conditions for short periods of time, the
humidity will condense in the crankcase
and cause the oil to look creamy. Oil
contaminated by condensed water will
not provide adequate lubrication and
must be changed immediately. Using
contaminated oil will damage bearings,
pistons, cylinders and rings and is not
covered under warranty. To avoid water
condensation in the oil, periodically run
the compressor with tank pressure near
150 psi for two-stage compressors or 120
psi for single stage compressors by open-
ing the drain cock or an air valve con-
nected to the tank or hose. Run the
pump for an hour at a time at least once
a week or more often if the condensa-
tion reoccurs.
IMPORTANT: Change oil after first 50
hours of operation.
PRESSURE SWITCH, START - STOP
NOTE: This compressor has a maximum
operating pressure of 175 psi for two-
stage compressors or 135 psi for single
stage compressors. Do not alter pressure
settings on control components above
this limit.
The compressor unit starts and stops
based on preset pressure switch set-
tings. The pressure switch contains an
unloader which is a small valve that
vents air to allow the motor to start
easily (See Figure 6).

CONTINUOUS RUN OPERATION
To convert to continuous run operation a
separate unloading device must be
installed by the user between the pump
and the tank. The existing check valve
must be removed.

Premium and Professional Series
CRANKCASE BREATHER
During severe operating conditions or
initial start-up, some oil may accumulate
at the crankcase breather opening. This
is normal and will diminish as the pump
accumulates run time and the piston
rings become fully seated.
Maintenance
Disconnect, tag and lock
out power source then
release all pressure from
the system before
attempting to install, service, relocate
or perform any maintenance.
In order to maintain efficient opera-
tion of the compressor system, check
the air filter and oil level before each
use. The ASME safety valve should also
be checked daily (See Figure 7). Pull
ring on safety valve and allow the ring
to snap back to normal position. This
valve automatically releases air if the tank pressure exceeds the preset maxi-
mum. If air leaks after the ring has
been released, or the valve is stuck and
cannot be actuated by the ring, the
ASME safety valve must be replaced.

TANK
Unloader Never attempt to repair
or modify a tank!
Welding, drilling or any
other modification will
weaken the tank resulting in damage
from rupture or explosion. Always
replace worn, cracked or damaged
tanks.
NOTICE
!
Inspect tank carefully at a minimum of
once a year. Look for cracks forming
near the welds. If a crack is detected,
Do not attempt to
tamper with the
Drain liquid from
tank daily.
