Note: When the primary air cleaner elements are
cleaned, always begin with the clean side (inside) in
order to force dirt particles toward the dirty side
(outside).
Aim the hose so that the air flows inside the element
along the length of the filter to prevent damage to the
paper pleats. Do not aim the stream of air directly at
the primary air cleaner element. Dirt could be forced
further into the pleats.
Note: Refer to “Inspecting the Primary Air Cleaner
Elements”.
Vacuum Cleaning
Vacuum cleaning is a good method for cleaning
primary air cleaner elements which require daily
cleaning because of a dry, dusty environment.
Cleaning with pressurized air is recommended prior
to vacuum cleaning. Vacuum cleaning will not
remove deposits of carbon and oil.
Note: Refer to “Inspecting the Primary Air Cleaner
Elements”.
Inspecting the Primary Air Cleaner
Elements
Illustration 43 g00281693
Inspect the clean, dry primary air cleaner element.
Use a 60w blue light in a dark room or in a similar
facility. Place the blue light in the primary air cleaner
element. Rotate the primary air cleaner element.
Inspect the primary air cleaner element for tears and/
or holes. Inspect the primary air cleaner element for
light that may show through the filter material. To
confirm the result, compare the primary air cleaner
element to a new air cleaner element that has the
same part number.
Do not use a primary air cleaner element that has
any tears and/or holes in the filter material. Do not
use a primary air cleaner element with damaged
pleats, gaskets, or seals. Discard damaged primary
air cleaner elements.
Storing Primary Air Cleaner Elements
If a primary air cleaner element that passes
inspection will not be used, the primary air cleaner
element can be stored for future use.
