13.
Discard and replace the flush valve’s o-rings and seals, after reading the note
below.
Note: Do not replace o-ring (O-K-008) unless it is worn or damaged. This o-ring is
designed for use with all solvents. In some cases O-K-008 o-ring can be replaced
with the more economical o-ring (O-E-008).
Remove Actuating Stem
1. Unscrew the actuating stem from the valve rod. Tightly clamp the actuating stem
into a soft jawed vise and rotate the whole gun block.
Note: The screw driver slot in the end of the actuating stem should not be used for
removal as if it becomes damaged the stem will not fit into the actuator bushing.
Make sure the actuating stem is smooth or it will wear out the actuator bushing.
