Inspect Filter

Air restriction indicator will not signal correctly if an filter has a break or is not correctly sealed in air cleaner housing. Throw away filter that has even the slightest damage. If gasket is broken or missing, install a new element.

  1. Hold a bright light (A) inside filter and check carefully for holes. Discard any filter that has even the slightest hole.

  2. Be sure outer screen (B) is not dented. Vibration would quickly wear a hole in filter.

  3. Be sure filter gasket (C) is in good condition. Press the gasket on the new filter to see if it springs back. Make sure the new filter has a highly compressible gasket that springs back when finger pressure is released. If gasket is damaged or missing, replace filter.
