2.0 Routine Maintenance
Maintenance is a planned program which provides an orderly series
of service and inspection procedures, together with cleaning. A well
planned maintenance program lowers maintenance costs, reduces
down time and can prevent possible accidents due to failed
components.
Shut down the Welder/ Compressor for 5 minutes to allow
system to depressurize.
