4.1 Remove the right housing (7) as shown
in operation 3.1
4.2 Undo the 3 mounting screws holding
the pump (14) and remove the pump first by
sliding it away from the orifice and then lift-
ing it out. This sequence is important
because the orifice reaches inside the
pump. Lifting the pump before sliding it
away will damage the orifice tubes.
4.3 Unscrew the orifice
4.4 Use a .6mm drill to clean out each ori-
fice stem.
