9. Cleaning air cleaner element (dual element)
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 premature wearing.
For operation in a dusty environment, clean the air cleaner
element every 50 hours or earlier and replace it every 400
hours or earlier.
For operation in a normal condition, clean it every 100
hours and replace it every 1000 hours or every year.
(1) Open the cap and take out the outer element. Tap
dust out of the outer element. If much dust on the
element, blow air from inside of the element. Be
careful not to damage the fins.
(2) Return the outer element, close the cap as “TOP” mark
upward and clip firmly.

IMPORTANT
1) Do not take out the inner element. It avoid from getting
dust into the engine air intake part. It is not necessary
to replace the inner element unless it is damaged or
very dirty.
2) Never operate engine with inner element only. Inner
element cannot catch fine dust like as the outer
element.
