Cleaning the Air Filter Element

The air filter element can be cleaned by using the following methods.
pressure air
Vacuum cleaningPressurized Air
Pressurized air can be used to clean air filter elements. Pressurized air will not remove deposits of carbon and oil. Use filtered, dry air with a maximum pressure of 207 kPa (30 psi).

Note: When the air filter 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 air 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 air directly at the air filter element. Dirt could be forced further into the pleats.Vacuum Cleaning
Vacuum cleaning is another method for cleaning air filter elements which require daily cleaning because of a dry, dusty environment. Cleaning with pressurized air is recommended prior to vacuum cleaning. Vacuum cleaning will not remove deposits of carbon and oil.Replace the air filter element after the air filter element has been cleaned six times. Also replace the air filter element if the air filter element has been in service for 2000 hours.Replacing the Air Filter Element
The air filter element should be replaced immediately if the element is damaged.
