C05019 Air Filtration System C5-5
Have a new safety (secondary) filter element on
hand before removing the used filter element. Do
not keep the intake system open to the
atmosphere any longer than necessary.
5. If the safety filter element must be replaced,
remove the indicator and remove the safety fil-
ter element. Discard the filter element. Do not
clean the damaged or dirty safety filter element.
6. Reset the safety filter indicator from red to
green by gently blowing air into the threaded
hole from gasket side of the indicator nut.
7. Install the new safety filter element. Tighten the
wing nut to 13 N•m (10 ft lbs).
8. Install main filter element (10) into the air
cleaner and secure it with wing nut (5). Tighten
the wing nut hand tight. Do not use a wrench or
pliers. If the original filter element is being
reused, ensure the sealing gasket is not
damaged. The gasket must seal completely.
9. Close and latch the dust collectors on the bot-
tom of the air cleaner assembly.
AIR CLEANER ASSEMBLY CLEANING
Main Filter Cleaning
Only the main filter elements may be cleaned,
and then only if they are structurally intact. Do
not reuse an element that is damaged. Do not
clean and reuse the safety (secondary) filter
elements. Replace them with new parts.
After inspection, determine the condition of the main
filter element and choose either the washing method
or compressed air method for cleaning the element.
If the element is clogged with carbon, soot, oil and/or
dust, the complete washing procedure will produce
the best results.
Wash elements with water and detergent as follows:
1. Soak the element in a solution of detergent and
water for at least 15 minutes. Rotate the
element back and forth in the solution to loosen
dirt deposits. Do not soak elements for more
than 24 hours.
2. Rinse the element with a stream of fresh water
in the opposite direction of normal air flow until
rinse water runs clear. Maximum permissible
water pressure is 276 kPa (40 psi). A complete
and thorough rinse is essential.
3. Dry the element thoroughly. If drying is done
with heated air, the maximum temperature must
not exceed 60°C (140°F) and must be
circulated continually. Do not use a light bulb to
dry elements.
