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.
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 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 is stuck and
cannot be actuated by the ring, the
ASME safety valve must be replaced.

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.
NOTICE
!
The tank should be carefully inspected
at a minimum of once a year. Look for
cracks forming near the welds. If a crack
is detected, remove pressure from tank
immediately and replace.
COMPRESSOR LUBRICATION
See Operation. Add oil as required. The
oil and oil filter should be changed every
MAINTENANCE SCHEDULE
Daily
Do not attempt to
tamper with the
Drain liquid from
tank daily.
Weekly Monthly
6
three months or after every 500 hours of
operation; whichever comes first. Only
pressure lubricated pumps have an oil
filter.
AIR FILTER
Never run the compressor pump without
an intake air filter nor with a clogged
intake air filter. Use compressed air to
blow the filter clean. Do not wash or oil
the element. If it cannot be blown clean,
the filter must be replaced. Operating
compressor with a dirty filter can cause
high oil consumption and increase oil con-
tamination in the discharge air.
INTERCOOLER (TWO-STAGE
COMPRESSORS ONLY)
Intercooler fins are
sharp, always wear
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
pressure to blow dust and foreign
material from cylinder head, motor, fan
blades, air lines, intercooler and tank on
a monthly basis.
BELTS
Lock out and tag
the power then
release all pressure from the tank to pre-
vent unexpected movement of the unit.
Check belt tension every 3 months.
Adjust belt tension to allow 3/8 to 1/2"
deflection with normal thumb pressure.
Also, align belts using a straight edge
against the face of the flywheel and
