ter element (9). See Parts on page 10. The filter ele-
ment (9) needs to be cleaned or replaced when the
indicator (3) is 3/4 red.

(9), and spring (7) on hand.
2. Follow Pressure Relief Procedure, page 7.
3. Open the fluid drain valve (B, see F
IG
. 1), if used, or
remove the filter plug (8); have a container ready to
catch the drainage.
4. Remove the bowl (2), element (9), and spring (7).
5. Replace immediately with the spare bowl (2), ele-
ment (9), and spring (7) to keep the paint from dry-
ing on the housing (1) and other parts.

b. Lubricate the threads of the bowl (2) with
grease before screwing it to the housing (1).
Tighten securely.
6. Clean the bowl (2), element (9), and spring (7) you
removed with a compatible solvent before the paint
dries. Store until needed.
