maintenance, you may be exposed
to voltage sources, compressed
air, or moving parts. Personal
injuries can occur. Before perform-
ing any maintenance or repair, dis-
connect power source from the
compressor and bleed off all air
pressure.
To ensure efficient operation and
longer life of the air compressor out-
fit, a routine maintenance schedule
should be prepared and followed.
The following routine maintenance
schedule is geared to an outfit in a
normal working environment operat-
ing on a daily basis. If necessary, the
schedule should be modified to suit
the conditions under which your
compressor is used. The modifica-
tions will depend upon the hours of
operation and the working environ-
ment. Compressor outfits in an
extremely dirty and/or hostile environ-
ment will require a greater frequency
of all maintenance checks.
NOTE: See "Operation" section for
