Cleaning the Primary Air Cleaner
Elements
NOTICE
Perkins recommends certi
fi
ed air
fi
lter cleaning ser-
vices that are available at Perkins dealers. The
Perkins cleaning process uses proven procedures to
assure consistent quality and suf
fi
cient
fi
lter life.
Observe the following guidelines if you attempt to
clean the
fi
lter element:
Do not tap or strike the
fi
lter element in order to re-
move dust.
Do not wash the
fi
lter element.
Use low pressure compressed air in order to remove
the dust from the
fi
lter element. Air pressure must not
exceed 207 kPa (30 psi). Direct the air
fl
ow up the
pleats and down the pleats from the inside of the
fi
lter
element. Take extreme care in order to avoid damage
to the pleats.
Do not use air
fi
lters with damaged pleats, gaskets, or
seals. Dirt entering the engine will cause damage to
engine components.
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
fi
lter 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 two common methods that are used to
clean primary air cleaner elements:
•
Pressurized air
•
Vacuum cleaning
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
fi
ltered, dry air with a
maximum pressure of 207 kPa (30 psi).

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
fl
ows inside the element
along the length of the
fi
lter in order to help 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.

Elements”.
