Air Cleaner Element - Clean, Check and Replace

When handling compressed air, wear safety goggles, a dust mask, a hardhat, gloves and other necessary protec-
tive gear. Working without wearing proper protective gear could result in serious injuries.
Never perform maintenance on the air cleaner while the engine is running. Servicing the pre-cleaner while the
engine is running can cause particles of foreign material to enter the engine and result in rapid wear of parts, lead-
ing to a shorter service life of the engine. Never tap, hit or wash the air cleaner element.
If defects such as cuts, pinholes or local wear are found in the element, or if the air cleaner indicator shows a red
sign soon after the cleaned element is installed, change it for new one. Remove the air cleaner slowly to prevent
foreign materials accumulated on the element from falling off.
After removing the air cleaner, immediately cover the air inlet with plastic sheet or similar means to prevent foreign
materials from entering the engine.
1. Remove the air cleaner cap and wing bolt.
2. Remove the air cleaner element from the body.
3. Blow compressed air (0.69 MPa {7 kgf/cm
psi] or lower) onto the inside surface of the element
to remove foreign materials.
4. To remove dust stuck on the air cleaner element,
blow dry compressed air onto the outside surface
from a distance.
Blow compressed air on the inside surface toward
the outside along the pleats. Then, blow com-
pressed air on the outside and inside surface
again.
5. After cleaning, hold the air cleaner element near a
light bulb to illuminate the inside, to check for de-
fects such as cuts, pinholes or local wear.
6. If any defect is found, replace the air cleaner ele-
ment with a new one.
7. Reassemble the air cleaner element as it was.
