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. Works without wearing proper protective gear could result in serious injuries.
Never service the air cleaner while the engine is running. Servicing the air cleaner while the engine is in operation
can cause particles of foreign matter to enter the engine and result in rapid wear of parts, leading to a shorter ser-
vice life of the engine. Never knock or hit the element.
Cleaning, inspecting and replacing procedure described below is a commonly used procedure. Some application
may be equipped with different air cleaner.
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 dust and other contaminants.
4. To remove dust stuck on the element, blow dry
compressed air onto the outside surface from a dis-
tance.
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 element near a light bulb to
illuminate the inside, to check for defects 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 is.
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, replace the filter element.
Reset the indicator by pressing the reset button to
erase a red sign after installing the clean or new ele-
ment.
