Cleaning, Inspecting And Changing Air Cleaner Element - Mitsubishi S12U Operation & Maintenance Manual

Cleaning, Inspecting and Chang-
ing Air Cleaner Element
When handling compressed air, wear safety gog-
gles, hardhat, gloves and other necessary protec-
tive gear. Compressed air may cause personal
injury when not wearing the proper protective gear.
Do not service the air cleaner while the engine is
running. Maintenance of the air cleaner while the
engine is in operation can cause dust to enter the
engine and result in rapid wear of parts, leading to a
shorter service life.
Never knock or hit the element.
1 Remove the air cleaner cap or the wing nut.
2 Pull out 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 ele-
ment to remove dust and other contaminants.
4 To remove dust stuck on the element, blow dry
compressed air onto the outside surface from a
distance.
Blow compressed air on the inside surface
toward outside along the net pattern.
Then, blow compressed air on the outside and
inside surface again.
5 After cleaning, place a light bulb in the element
to check for damage, pinholes and worn sec-
tions.
6 If any breakage are found, replace the air
cleaner element with the new one.
7 Reinstall the air cleaner element after cleaning,
inspecting or replacing the air cleaner element.
If abnormalities such as damage, pinholes and thin
sections are found in the element or if the air
cleaner indicator shows red sign soon after the
cleaned element is installed, install a new filter ele-
ment in the air cleaner.
If the indicator shows a red sign, after the clean ele-
ment is installed, reset the indicator by pressing the
reset button.
