Filter Function and Conditions Requiring Service
This air filter prevents solid particles from contaminating components in the vacuum system.
CAUTION: Examine air filter regularly and empty when necessary.
Open each filter regularly to determine whether liquid or other contaminants are trapped inside.
Remove any liquid or contaminants found. Clean or replace the filter element if it has an overall
dirty appearance, or if there is a noticeable increase in the time required to attain full vacuum
(see REPLACEMENT PARTS LIST).
