6. Remove the static valve assembly from the system and place it on the

workbench (see

Figure 5-21

7. Using a 2.5-mm hex wrench, remove

the two mounting screws that secure
the valve body to the base plate of
the valve assembly.

8. Follow these steps to remove the piston from the static valve:

a. Locate the slot in the piston

holder. If necessary, rotate the
piston holder so that the opening
in the slot faces up.

b. Guide the piston out of the

piston holder by lifting the valve
body straight up. This removes
both the piston and the valve
body.

Do not drop the piston.

Figure 5-21. Static Valve

Dropping the piston may cause scratches or breakage. If the piston is
damaged, it cannot be used again and must be replaced.
