Hand operation of the lubricator is accomplished
removing the top cover 48 and applying the priming

is furnished with the lubricator. The
priming handle must be removed and the top cover re­
and secured after this operation has been com-
Lubricating Oil
It is imperative that only lugtl grades of lubricating
oils of a suitable type and viscosity be used in this lubri­
cator to obtain proper lubrication of the compressor and
associated devices. Since in general, each user has hi"
own specifications for oil, no attempt is made here to
a specification. If desired, however, W. A. B. Co.
specifications for recommended lubricants will be sup­
plied upon request.
Maintenance and General Care
The strainer in the filler inlets should be
and inspected from time to time and cleaned if necessary.
When the lubricator is removed for general inspection,
it should be subjected to prescribed tests before
returned to service. Cart:: must be exercised to replace
each pump in the p.vlinder from which it was removed.
REPAIR SHOP AN);) ROAD TESTS
The Interstate Commerce Commission's "Rules and
Instruction for Inspection and Testing of Steam Loco­
motives and Tenders" dated 1919, snecified as follows
regarding steam compressor tests:
"The compressor or compressors shall be tested for
capacity by orifice test as often as conditions may re­
but not less frequently than onre each three
months."
The above Rules and Instructions also specify that
with a 9-32" orifice to atmosphere and main reservoir
pressure maintained at 60 pounds, the 8%" compressor
must make not more than 100 single strokes per minute.
For altitudes Dver 1,000 feet, the speed of the compressor
may be increased five single strokes per minute for each
1,000 feet increase altitude.*
Wc recommend the following method for making the
above test:
Before making any test, the main reservoir should
be drained and it and its connections should be tested
for leakage as follows: After obtaining the main reser­
voir pressure corresponding to the governor setting, close
the throttle to the compressor. Then close the main res­
ervoir cut-out cock when the SD (or SF) governor is
used; if, however, the SG type of governor or the SF
with a manifold providing for a single main reservoir
'NOTE-The above figures are for 8%"-150 compressor
only. The use of a
UN
diameter orifice atmosphere with the
8%"-120 compressor, other test conditions remaining the same,
will provide approximately the same relative condemning point for
this machine.
