General Recommendations
To ensure efficient operation and longer life of the air
compressor, prepare and follow a routine maintenance
schedule. The routine described in this section is intended for
an air compressor used under normal daily working conditions.
If necessary, modify the schedule to suit the conditions under
which you use your compressor. Modifications will depend
upon hours of operation and working environment. Operating
air compressors in extremely dirty or hostile environments will
require more frequent maintenance checks.
NOTE: See Features and Controls and Operation for control
locations.
Inspect Safety Valve
1. Pull ring on safety valve (A) and observe that safety
valve operates freely.
2. If valve is stuck or does not operate smoothly, it must
be replaced with same type of valve. Take unit to
authorized service facility for repair.
Inspect Tank Drain Valve
1. Push ON - OFF switch to OFF and unplug unit.
2. Disconnect air tool or accessory from unit.
3. Pull ring on safety valve to reduce air pressure. Release
safety valve ring.
4. Open drain valve (turn fully counterclockwise) and
permit accumulated water to be discharged. Valves
should operate smoothly and have full range of
operation.
5. After water has drained, close drain valve fully
clockwise.
NOTE: If drain valve is plugged, pull safety valve ring to fully
drain air from tank. Remove, clean and reinstall drain valve
