10. Cleaning air cleaner elements (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.
Lift the front end part of air cleaner.
(2) 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.
(3) Return the outer element, close the cap as “TOP”
mark upward and clip firmly.
(4) Push down the front end part of the air cleaner to the
original position.

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 inner element as long as no
damage on it or too much dirty.
2) Never operate engine with inner element only.
Inner element can not work as outer element.
