1. Before starting compressor, pull
the ring on the safety valve to
make sure that the safety valve
operates freely. If the valve is
stuck or does not operate
smoothly, it must be replaced
with the same type of valve.
To ensure efficient operation and longer life of the air compressor, a routine
maintenance schedule should be prepared and followed. The above routine
maintenance schedule is geared to an air compressor in a normal working
environment operating on a daily basis. If necessary, the schedule should be
modified to suit the conditions under which your air compressor is used. The
modifications will depend upon the hours of operation and the working
environment. Compressors in an extremely dirty and/or hostile environment will
require a greater frequency of all maintenance checks.
Risk of Unsafe 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.
