Cleaning the Air Filter
WARNING: 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 you may
need to remove these deposits to restore perfor-
mance. We highly recommend that only qualified
service technicians perform this service.

WARNING: Keeping air intake vents free of grass
and debris prevents motor overheating and possible
failure.
