CLEAN AIR FILTER
Air Filter
Cleaning the air filter:
A dirty air filter decreases engine perform-
ance and increases fuel consumption and
harmful emissions. Always clean after every
5 hours of operation.
1. Clean the cover and the area around it to
keep debris from falling into the carbure-
tor chamber when the cover is removed.
2. Remove parts as illustrated.
