The secondary air cleaner element is not serviceable
or washable. The secondary air cleaner element
should be removed and discarded for every three
cleanings of the primary air cleaner element. When
the engine is operating in environments that are
dusty or dirty, air cleaner elements may require more
frequent replacement.

Cleaning the Primary Air Cleaner
Elements
The primary air cleaner element can be used up to
six times if the element is properly cleaned and
inspected. When the primary air cleaner element is
cleaned, check for rips or tears in the filter material.
The primary air cleaner element should be replaced
at least one time per year. This replacement should
be performed regardless of the number of cleanings.
Use clean primary air cleaner elements while dirty
elements are being cleaned.
NOTICE
Do not clean the air cleaner elements by bumping or
tapping. This could damage the seals. Do not use el-
ements with damaged pleats, gaskets or seals. Dam-
aged elements will allow dirt to pass through. Engine
damage could result.
Visually inspect the primary air cleaner elements
before cleaning. Inspect the air cleaner elements for
damage to the seal, the gaskets, and the outer cover.
Discard any damaged air cleaner elements.
There are four common methods that are used to
clean primary air cleaner elements:
• Pressurized water
• Pressurized air
• Vacuum cleaning
• Washing with nonsudsing detergent
Pressurized Water
Pressurized water will clean the primary air cleaner
element unless carbon and oil have accumulated on
the surface of the primary air cleaner element. The
maximum water pressure for cleaning purposes must
be below 275 kPa (40 psi). Do not use a spray
nozzle.
Note: When the primary air cleaner element is
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 water flows inside the
element along the length of the filter in order to help
prevent damage to the paper pleats. Do not aim the
stream of water directly at the primary air cleaner
element. Dirt could be forced further into the pleats.
Note: Refer to “Drying the Primary Air Cleaner
Elements”. Refer to “Inspecting the Primary Air
Cleaner Elements”.
Pressurized Air
Pressurized air can be used to clean primary air
cleaner elements that have not been cleaned more
than two times. Pressurized air will not remove
deposits of carbon and oil. Use filtered, dry air with a
maximum pressure of 207 kPa (30 psi).
