D. Cleaning/Replacing Air Cleaner
Your engine has an air cleaner which helps prevent premature engine wear and failure. NEVER run engine without complete air cleaner installed on engine. Your air cleaner periodically needs to be cleaned or replaced. To do this, you first need to determine the type of air cleaner on your engine. Your engine will be equipped with one of the following air cleaners; Type A, B, C, D or E. Follow instructions for the air cleaner type that resembles your model. See Figures 48 thru 52 starting on page 19. Afterward, continue reading instructions below.
NOTES
ALWAYS inspect filter(s) for discoloration or dirt accumulation. If either is present, see "I. Servicing Foam Filters" instructions on this page, and/or see "II. Servicing Paper Filters" instructions on page 19. Afterward, continue reading instructions below.
