Risk of Unsafe Operation. Unit cycles automatically when power is on. When servicing, you may be exposed to volt-

age sources, compressed air, or moving parts. Before servicing unit unplug or disconnect electrical supply to the air compressor, bleed tank of pres- sure, and allow the air compressor to cool.

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 environ- ment. Compressors 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

Risk of Bursting. If the safety valve does not work properly, over-pressurization may occur, causing air tank rupture 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.
