Operation. Unit
cycles automatically when power
is on. When servicing, you may
be 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 lon-
ger life of the air compressor, a rou-
tine 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 ba-
sis. 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 work-
ing 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 the
location of controls.
