The Engine Air Cleaner
When the air cleaner element becomes
dirty, the engine does not start smoothly,
and sufficient output cannot be obtained.
Machine operation will be affected and the
engine life will be shortened greatly. Do not
forget to clean the element. (For details,
please see the separate engine operation
manual.) If the element cannot be cleaned,
replace it with a new one.(Fig.27)
