Filter Function and Conditions Requiring Service
An 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 in the filter bowl. Clean or replace the filter screen if
it has an overall dirty appearance, or if there is a noticeable increase in the time required to
attain full vacuum.
Filter Service Procedures
1) Unscrew the hex shaped bowl (4) from the body (1) of the air
filter. Support the filter body while twisting the bowl, to protect
the vacuum line fittings from being damaged.
Note: Do
not attempt to remove the snap ring on the bowl.
2) Remove any liquid or other contaminants in the bowl, and
determine whether the filter screen (2) needs further attention
(see Conditions Requiring Service preceding).
If so , proceed to
step 3; if not , skip to step 7.
3) Remove the filter screen from the bowl, taking care not to
damage the screen.
4) Clean the screen with mild soap and water, using compressed air
to remove any liquid or other contaminants. If the screen
cannot be cleaned adequately, replace it.
5) Clean the bowl interior and all internal parts, using mild soap and
water only. Do not use any other cleaning agents.
6) Install the new or cleaned filter screen in the filter body.
7) Lubricate the bowl seal (3) using a mineral base oil or grease, or
silicone.
8) Screw the bowl back into the body, taking care to avoid contaminating the filter screen with
lubricant. Tighten the bowl snugly with a wrench.
