air Filter element maintenance
1. Remove the air filter cover and the air
filter elements and check for dirt. Clean
or replace as described below.
2. Cleaning:
• For “paper” filter elements:
To prevent injury from dust and debris, wear
ANSI-approved safety goggles, NIOSH-
approved dust mask/respirator, and heavy-
duty work gloves. In a well-ventilated area
away from bystanders, use pressurized
air to blow dust out of the air filter. If this
does not get the filter clean, replace it.
• For foam filter elements:
Wash the element in warm water and mild
detergent several times. Rinse. Squeeze
out excess water and allow it to dry
completely. Soak the filter in lightweight oil
briefly, then squeeze out the excess oil.
3. Install the new filter or the cleaned filter.
Secure the Air Cleaner Cover before use.
