To ensure efficient operation and longer life of the air compressor outfit, a routine
maintenance schedule should be prepared and followed. The following routine
maintenance schedule is geared to an outfit in a normal working environment oper-
ating 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 outfits 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.
To Check Safety Valve
If the safety valve does not work properly, over-
pressurization may occur, causing air tank rup-
ture or an explosion.
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.
