Outer Primary Element
All air cleaner manufacturers agree that attempting to clean or wash an
element increases the chance for element damage. It is highly
recommended that you consider the value of cleaning an element against
the risks which could lead to engine damage. Adopt the policy that all
elements should be replaced with new and not cleaned.
Inner Safety Element
An inner safety element should never be washed or reused. Always install a
new element. Replace inner safety elements after every third primary
element change. DO NOT remove an inner safety element until you have
thoroughly cleaned the inside of the air cleaner canister. This will prevent
dirt, which could damage the engine, from entering the induction manifold.
CAUTION:
NEVER run the engine with only the inner safety
element installed. Severe engine damage will result from dust
entering the engine.
