CLEANING THE EXHAUST PORT AND MUFFLER
Depending on the type of fuel used, the type and amount of oil used, and/or your operating
conditions, the exhaust port and muffler may become blocked with carbon deposits. If you
notice a power loss with your petrol powered tool, a qualified service technician will need to
remove these deposits to restore performance.
