6.10 Air Filter Replacement
NOTE
A dirty air filter will restrict air flow to the carburetor. To prevent carburetor
malfunction, service the air cleaner regularly. Service more frequently when
operating the generator in dusty areas.
WARNING
Never use petrol or low flash point solvents for cleaning the air filter element. This
could result in a fire or explosion.
NOTE
Never run the engine without an air filter. Rapid engine wear will result from
contaminants such as dust and dirt being drawn in to the engine.
6.11 Unscrew the wing nut and remove the air filter cover (1).
6.12 Unscrew and remove the foam air filter element from the housing (2).
6.13 If there is light dust on the filter it can be blown clean with an airline.
6.14 Ideally the air filter should be replaced if dirty.
6.15 To reinstall, reverse the process.
