WHEN REQUIRED

CHECK, CLEAN AND REPLACE AIR CLEANER ELEMENT

If inspection, cleaning, or maintenance is carried out with the engine running, dirt will get into the
engine and the engine will suffer damage. Always stop the engine before carrying out these opera-
tions.
When using compressed air, there is danger that dirt may be blown around and cause serious injury.
Always use safety glasses, dust mask, and other protective equipment.
Cleaning the outer element
1. Open the engine hood at the rear of the machine, loosen
clip (2), remove dust cup (3).
2. Throw away the dust inside dust cup (3) and clean the
inside of the cup.
3. Take out element (4) and cover the air connector at the
end of the air cleaner body with a clean cloth or tape.
4. Clean interior of the air cleaner body.
5. Direct dry compressed air (less than 0.69MPa (7kg/cm
100 PSI)) to the element from inside along its folds, then
direct it from outside along its folds and again from inside.
1) Replace the element which has been cleaned 6
times repeatedly or used throughout a year.
2) Replace element when the dust indicator red piston
appears soon after installing the cleaned element
even though it has not been cleaned 6 times.
