cleaner elements
The air cleaner serves to keep the engine in favorable
conditions by removing dust in air and preventing the
cylinder liner and piston ring from wearing.
For operation in a dusty environment, clean the air
cleaner element every 50 hours and replace it every 300
hours.

said intervals, replace it every year.
