Slow turning

Slow turning

  • If a slow turning valve is fitted , then this will open instead of the main automatic valve if the engine has been stopped for more than 30 minutes during maneouvring.
  • It will only supply enough air to turn the engine over very slowly . This is a precaution in case a cylinder has oil or water leak into it which would cause damage to engine when starting.
  • If the engine completes a full revolution on slow turn , then the main automatic valve opens and engine will not start
