pump, and disconnect the air supply line
from the pump.

DRAWING.
Using a 9/16" wrench or socket, remove
the four hex capscrews (items 12). Remove
the air valve assembly from the pump.

Step #2: Disassembly of the air valve.
Using a 7/16" wrench or socket, remove
the eight hex capscrews (items 1-F) that
fasten the end caps to the valve body.
Next remove the two end caps (items 1-E).
Inspect the two o-rings (items 1-D) on each

Wipe spool with a soft cloth and inspect for
