4.5 Stopping Procedures
① Close the service valve completely and operate the machine about 5 minutes, until it cools
down.
② Turn the starter switch to “STOP” position to stop the engine.
③ Remove the key from the compressor every time when you stop the engine. Keep the key and
be careful not to lose it.
Unless all the service valves are fully closed upon stopping operation, the compressed air will be
sent in reverse direction in the hoses (pipes) connected to air tools and relieved to atmosphere
continuously through the auto-relief valve. Further, when re-starting operation next time,
compressor oil will be jetted out through service valves.
