Preliminary Work

Information 

• If an air cleaner housing, which was last replaced four years ago, is opened before the relevant service interval is reached (e.g. visual inspection at the request of the customer or similar situation), the air-cleaner element must be replaced and the housing must be cleaned. 
• A used air-cleaner element (which was last replaced four years ago) must not be re-installed due to the risk of leaks in the housing (loss of elasticity in the air-cleaner seal over time). 
• Always replace the air-cleaner element when you open the air cleaner housing (which was last replaced four years ago)!
