Be careful when plate is put against the air inlet opening.Excessive suction can pull the plate quickly against the air inlet opening.To avoid crushed fingers, do not put fingers between plate and air inlet opening.
Place a service person in position near each turbocharger air inlet. Equip the service person with a piece of steel plate. Each piece of steel plate must be large enough to completely cover each turbocharger air inlet.
Start the engine. If the engine starts to run too fast or the engine runs out of control, immediately activate the emergency stop button or else put the steel plates against the turbocharger air inlets. This will stop the air supply to the engine, and the engine will stop.
