(optional part)
You can purchase an optional, USDA-qualified spark arrester for this product
from your authorized Honda Power Equipment dealer. Spark arresters are
required in some areas; check local laws and regulations before operating this
Honda product.

The muffler becomes very hot during operation and remains
hot for a while after the engine stops. Be careful not to touch the muffler
while it is hot. Allow it to cool before proceeding.
The spark arrester must be serviced every 100 hours to maintain its
efficiency.
1. Remove the four 6 mm bolts and remove the muffler protector.
2. Remove the two 5 mm screws from the exhaust pipe tip. Remove the
exhaust pipe tip and spark arrester (be careful not to damage the spark
arrester screen).
3.
Use
a wire brush to remove carbon deposits from the spark arrester
screen.
NOTE: Inspect the spark arrester screen for holes or tears. Replace it if it
is damaged.
