Replacing the Spark Arrestor
See Figure 9.
NOTE:
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 gas powered
tool, you may need to remove these deposits to restore
performance. We highly recommended that only qualified
service technicians perform this service.
The spark arrester may need to be replaced after repeated
use. If replacement is necessary, use Toro part number
