Inspecting and Cleaning Fresh Air Intake Filter Element
1.
Tap the sides of the filter element gently to loosen dirt. Do
NOT
tap the element against a hard surface.
2.
Using a dry element cleaner gun, clean the element with compressed air.
IMPORTANT:
Air pressure must
NOT
exceed 414 kPa (60 psi). Do
NOT
direct air against the outside of the element, as dirt might be
forced through to the inside.
3.
Hold the air nozzle next to the filter element
’
s inner surface, and move up and down the pleats.
4.
Repeat the previous steps to remove additional dirt as required.
5.
Hold a bright light inside the element and check carefully for holes. Discard any element that shows the slightest hole.
6.
Check the outer screen for dents. Vibration would quickly wear a hole in the filter.
7.
Check the filter gasket for cracks, tears, or other signs of damage. If the gasket is damaged or missing, replace the
element.
