Dry-type air cleaner elements
should be replaced after one year of
service or when the maximum allow-

to When to Service the Dry Type Air
Cleaner (page 61).
Inspect the entire air system for leaks
daily. Look especially for torn air inlet pip-

clamps. Have worn or damaged parts
repaired or replaced, as required.
Retighten any loose connections.
