•Air filter seal does not fit tightly against case •Air filter seal is distorted, worn, or damaged •Air filter element has holes or other damage •Air filter element is saturated with dirt •Air filter element is soaked with fuel mix
6.If air filter is in good condition and can be cleaned and reused, lightly brush debris from air filter element, or blow filter element clean using low pressure (40 psi or less) compressed air directed at inside of filter.
IMPORTANT
When using compressed air, always direct air stream at inside surface of filter so dust and debris will be blown out of filter. Keep air nozzle 6 - 8 inches away from filter to prevent damage to filter.

NOTICE

Continued operation with a damaged or excessively dirty filter will allow dirt and debris to enter engine, and result in poor performance, rapid engine wear, and premature engine failure.
