9. Using a 3.0 mm hex key (P/N 062338), loosen the two screws on the
pump head with the defective seal. Remove the screws, and then carefully
remove the head and place it on a clean surface.
10. Remove the seal wash body from the pump head. Or, if the seal wash
body was not removed with the pump head in Step 9 , pull it straight out of
the pump mechanism now.
11. Pull the piston out of the pump mechanism.
NOTE
A magnet secures the piston in place. If the magnetic
force makes the piston difficult to remove, tilt the pis-
ton to one side and then pull it out of the pump mecha-
nism.
