Disassemble the inlet and outlet valve units by screwing on an M8 screw long enough to act on the valve and
extract the valve guide from the valve seat (4, fig 17).
If the inlet valve seats remain glued to the head (for example due to incrustation caused by
prolonged pump inactivity), operate as follows:
For HF18A version, use tool p/n’s F26019400, F27513700 and F27513400 (fig. 18 and fig. 19).
For HF22A and HF25A, use tool p/n’s F26019400, F27513700 and F27513400 (fig. 18 and fig. 19).
Note: Always slip off the handle p/n F27513400 before extracting the seats.
