Engine Error Codes

Engine `NO RESTART'. If this message appears theengine will continue to run to allow the machines to bemoved to a position of safety where the machine can berepaired. Once the engine is stopped it will not restart untilthe repair as been carried out.

If the message `LOW POWER' displays the engine poweris reduced to 60% power to protect the engine.
