Prior to starting the diesel engine, the MVX valve must be latched open by rotating the reset lever clockwise as far as possible. Once latched, the reset lever will remain in the latched open position until manually released by the stop button.
To carry out an emergency closure of the MVX intake valve to stop the engine, either press or pull the stop button on the valve. No attempt should be made to restart the engine until the MVX valve is again latched open.
