Cleaning the air filter element
The air filter protects the engine from dirt
which can enter with the intake air and cause
rapid engine wear. This dirt is filtered from
the air by the air filter element. This model
uses a cartridge type air filter element which
consists of foam rubber moistened with oil.
When this filter element becomes dirty it
should be cleaned with solvent and reoiled.
Cleaning method
1. Remove the air filter element from its
case, remove element from core and
clean with solvent. After cleaning,
remove the remaining solvent by
squeezing the foam rubber.
