Instructions: Use clamps of the appropriate series to secure all hose connections. Degrease hose connection pipes and supercharging system hoses before installation. Only the union connections should be lightly lubricated with oil on the lip seal and sealing surfaces. The supercharging system must be sealed. Self-locking nuts must be replaced. Fill the turbocharger with engine oil through the connecting pipe for the feed oil line. After installing the turbocharger, let the engine run at idle speed (do not increase the speed) for 1 minute to ensure that oil is supplied to the turbocharger. Observe the rules for maintaining cleanliness.
