exposed to voltage sources,
compressed air, or moving parts.
Before servicing unit unplug or
disconnect electrical supply to the
air compressor, bleed tank of
pressure, and allow the air
compressor to cool.
To ensure efficient operation and
longer life of the air compressor unit,
a routine maintenance schedule
should be prepared and followed.
The following routine maintenance
schedule is geared to a unit in a
normal working environment
operating on a daily basis. If
necessary, the schedule should be
modified to suit the conditions under
which your compressor is used. The
modifications will depend upon the
hours of operation and the working
environment. Compressor units in an
extremely dirty and/or hostile
environment will require a greater
frequency of all maintenance checks.
NOTE: See "Operation" section for
