Foam Air Filter Replacement

The foam air filter should be cleaned every 30 days (more frequently in environments with high levels of dust). If, after cleaning, it is determined that the filter is degrading, it should be replaced.

  The equipment images in this document may differ slightly from your equipment, however the instructions are the same unless otherwise noted.
