C) Disassembling the Dispensing Head
Loosen and remove the two dispensing head-retaining
knobs. The knobs are removed by turning counter
clockwise until loose.
Remove the dispensing head by pulling straight out and
away from the machine.
Disassemble the dispensing head by first opening the
dispensing handle.
Pull the handle-retaining rod out far enough to allow
the handle to disengage.
Return the retaining rod to its original position. Using
the metal rod as a base, lever the piston from the
dispensing head with the handle.
Using the oring removal tool, remove the orings from
each of the piston.
Turn the dispensing head over and remove the large
oring from the rear of the dispensing head.
