A general visual inspection should be made to the air inlet and exhaust system. Make sure that there are no signs of leaks in the system.
There will be a reduction in the performance of the engine if there is a restriction in the air inlet system or the exhaust system.
- Inspect the engine air cleaner inlet and ducting in order to ensure that the passageway is not blocked or collapsed.
Hot engine components can cause injury from burns. Before performing maintenance on the engine, allow the engine and the components to cool.
Making contact with a running engine can cause burns from hot parts and can cause injury from rotating parts.
When working on an engine that is running, avoid contact with hot parts and rotating parts.
- Inspect the engine air cleaner element. Replace a dirty element with a clean element.
- Check for dirt tracks on the clean side of the engine air cleaner element. If dirt tracks are observed, contaminants are flowing past the element.
