Inspecting Air Filter Insert

1. Shine light on insert interior with lamp and check closely for damage. Discard filter if there is any hole, as small as it might be.
2. Check exterior screen for any deformation. Vibrations quickly open up any hole in the filter.
3. Check if rubber sealing rings are in good condition. If they are damaged, replace filter with a new one.

IMPORTANT: Do not put engine in gear without properly installed filter.
