Why have you stopped production ?   We've had a few problems . One of the bolts has worked loose and a blade has snapped off .   OK . Make sure the power is switched off then tighten up all the bolts on the unit and replace the broken blade . Why is there oil all over the floor ?   I think the valve is faulty . I couldn't regulate the pressure and the seal burst . I tried opening the emergency valve but it was jammed .
