NOTE: Provided that the VENTURI SWITCH Mechanism is in
good condition, removing it is not necessary. The HOUSING

proceed by closely adhering to the following steps:
A. Remove the SWITCH RETAINING RING (37) by pushing on
the exposed Tip of the RETAINING RING with a brass O-ring
Tool until the Body of the RETAINING RING is no longer seated
in the Groove on the VENTURI SWITCH (35) (Fig. 10).
B. Place the end of the brass O-ring Tool through the Mouthpiece
opening in the HOUSING ASSEMBLY (5) and into the space
between the Body of the SWITCH RETAINING RING (37) and
the VENTURI SWITCH (35). Using caution not to damage the
HOUSING ASSEMBLY, slowly pull the SWITCH RETAINING
RING away from the VENTURI SWITCH to remove it (Fig. 11).
C. Grasp the VENTURI SWITCH (35) by the Adjustment Tab
and pull it straight up and out of the HOUSING ASSEMBLY (5) to
remove it. Remove and discard the VENTURI SWITCH O-RING
(36), and DO NOT reuse it.
D. Closely examine the VENTURI SWITCH (35) and the SWITCH
RETAINING RING (37) for signs of distortion, cracks, corrosion,
rust, or other damage. Discard if found.
