Breather, Crankcase; Crankcase Breather; Oil Change - Champion A Series Operating And Service Manual

Before and during maintenance work
be absolutely sure these rules are fol-
lowed:
A. Main electrical switch for motor
driven units is off and marked so
it cannot be accidentally turned
on.
B. Pressure in the air system is com-
pletely released.
C. Never reach hand into the crank-
case without being conscious of
the fact that the crankshaft can ro-
tate due to the position of the
counterweights.
D. Proper equipment and tools are
used.
Failure to observe these precautions
will result in injury or death.
OIL CHANGE -- When a new or overhauled unit is
placed in service, the oil should be drained at the end
of the first 50 hours operation and the crankcase thor-
oughly flushed with flushing oil. The oil should be
changed again after the next 100 hours operation so
that all polishing residue from working parts will be re-
moved from the crankcase.
Subsequent oil change periods must be determined by
checking the discoloration and physical condition of the
oil in the crankcase. Due to dust, dirt and atmospheric
conditions being different at various locations, it is not
practical to definitely state how often the lubricating oil
in the crankcase should be changed. Service given to
air filter and crankcase breather also has a direct bear-
ing on oil change interval, as does high humidity condi-
tions which contribute to formation of varnish deposits
through oxidation of the oil. The period for changing oil
is therefore regulated by local conditions. The oil, how-
ever, should not be used for more than 500 hours. Oil
filters should be changed every time the oil is changed.
Always provide clean containers, funnels and clean
storage of oil and cleaning fluids. Changing oil will be
of little benefit if done improperly.
Fill the crankcase through the opening on top of the
crankcase until oil is to the dipstick FULL mark. Wipe
away all dirt before removing the oil filler plug. After the
unit has operated for several minutes, shut down the
compressor, check the oil level and add if necessary.
When starting the unit after an oil change, start under
no--load until assured that oil has reached all moving
parts.
Condensate accumulation in the crankcase will often
occur as a result of high humidity conditions, wide tem-
perature range and intermittent service.
CRANKCASE BREATHER -- The crankcase breather
should be washed each time the oil is changed. Inspect
the element and replace if it shows signs of wear. Main-
tain the breather in first class repair to prevent dirt from
entering the oil system.
AIR FILTER -- Servicing the air filter is one of the most
important maintenance operations to be performed to
insure long compressor life. Study these instructions
carefully and plan maintenance accordingly. Servicing
frequency is dependent on the dirt and vapor content
of the atmosphere, as well as type of filter used, and
must be determined by the user. Daily maintenance
is not uncommon in extremely dusty conditions.
The best method is to service very frequently until a
proper routine is established for existing conditions. In
many cases filter service can be greatly reduced by a
careful selection of location.
Not only is the timing of service important, but also the
manner in which it is done. Service with care so parts
are not damaged and be sure to assemble the filter cor-
rectly. Many air borne dirt particles and other materials
are extremely abrasive and cause rapid wear or corro-
sion if allowed to enter the compressor. It is therefore
important to use clean rags and cleaning fluids for
cleaning, and to be sure dirt doesn't enter the compres-
sor intake while the filter is off. Inspect the intake open-
ing for dirt, and if found, determine the cause before
continuing to operate the unit. Inspect flange connec-
tions, suction lines, hose connections, etc., for leaks.
Make sure all filter gaskets and clamps are tight. A
small leak will offset the most rigid maintenance
program.
Never operate the compressor with a
damaged filter or while servicing the
filter.
Unless otherwise specified dry type filter silencers with
replaceable elements are furnished. If other make or
