Cleaner (primary) and secondary element. Due to the dusty conditions created during operation, it
is necessary to service the air cleaner when it becomes clogged with dirt. Follow the steps in
to service the primary air cleaner. Check the secondary element (safety) only if the primary air
cleaner element was damaged. Follow the steps in Table 6-3 to change the secondary air cleaner.
