CLEANING THE EXHAUST PORT AND
MUFFLER
NOTE: Depending on the type of fuel used, the type and
amount of oil used, and/or your operating conditions, the
exhaust port, muffler, and/or spark arrestor screen may be-
come blocked with carbon deposits. If you notice a power loss
with your gas powered tool, you may need to remove these
deposits to restore performance. We highly recommended
that only qualified service technicians perform this service.
SPARK ARRESTOR
The spark arrestor must be cleaned or replaced every 25
hours or yearly to ensure proper performance of your product.
Spark arrestors may be in different locations depending on
the model purchased. Please contact your nearest service
dealer for the location of the spark arrestor for your model.
