4. Clean the outer element using either method A,
B, or C, depending on the element’s condition.
Methods A or B should be used for dry dust.
Method C should be used if the element is sooty,
oily or heavily contaminated, or after cleaning the
element six times using methods A or B.
Method A
Lightly tap the ends of the element against the
palm of the hand.
IMPORTANT: Do not tap the element against a hard
surface as this damages the element.

Method B
Use compressed air, not exceeding 2 bar (30
PSI). Insert the air line nozzle inside the element.
Hold the nozzle 150 mm (6″) from the element
and blow the dust from the inside through the
element to the outside.
WARNING
Wear eye protection and a face mask when
carrying out this operation.

Method C
Immerse the element in warm water containing
a small amount of non-sudsing detergent. Allow
to soak for at least 15 minutes. Keep the open
end of the element above the water line.
IMPORTANT: Never use fuel oil, gasoline, solvent or
water hotter than the hand can stand, otherwise the
filter element may be damaged.
After soaking, agitate the element in the water,
taking care not to allow dirty water outside the
element to splash over to the inside.
