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 existingcheck valve
must be removed.
ORANKCASE BREATHER
During severe operating conditions or
initial start-up, some oil may accumulate
at the crankcase breather opening. This
isnormal and will diminish asthe pump
accumulates run time and the piston
rings become fully seated.
Maintenance
I W.=d NINGI
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 8). 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 isstuck and
cannot be actuated by the ring, the
ASME safety valve must be replaced.
Do not attempt to
tamper with the
ASME safety valve.

TANK
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.
Drain liquid from
I NOTICE J tank daily.
The tank should be carefully inspected
at a minimum of once a year. Look for
cracks forming near the welds, if a crack
isdetected, remove pressure from tank
immediately and replace.
COMPRESSOR LUBRICATION
See Operation. Add oil asrequired. The
oil and oil filter should be changed every
three months or after every SO0hoursof
operation; whichever comesfirst. Only
pressure lubricated pumps have an oil
filter.
AIR FILTER
Never run the compressorpump without
an intake air filter norwith a clogged
intake air filter. Use compressedair to
blow the filter clean. Do not wash or oil
the element. If it cannot be blown clean,
the filter mustbe replaced.Operating
compressorwith a dirty filter can cause
high oil consumptionand increase oil con-
tamination inthe dischargeair.
INTERCOOLER (TWO-STAGE
COMPRESSORS ONLY)
r IAIADAIIAII_-] Intercooler fins are

gloves and use care when you clean or
work near the Intercooler.
Weekly, check the intercooler to be
sure all fittings are secure and tight.
Blow all dirt, dust and other accumula-
tions from the intercooler fins.
COMPONENTS
Turn off all power and use light air
pressureto blow dust and foreign
material from cylinder head, motor, fan
blades, air lines, intercooler and tank on
a monthly basis.

Also, align belts using a straight edge
against the face of the flywheel and
