Lever Height Adjustment

17. Pressurize the regulator

18. Slide the notch of the ad-

justing tool 125727 across

the top of the box bottom

(4) The top of the lever

(18) should touch the tool

without causing a leak. At

this point, the lever should

be 2.5 mm above the rim

of the box bottom.

19. If the notch in the tool

depresses the lever

causing a leak, in other

words, if the lever is

too high, unscrew the

locknut (16) with the ¼”

nut driver to lower the

lever (18) to the correct

height.

If the lever does not touch the tool, in other words, the lever

is too low, screw the locknut back in until the lever reaches

the correct height.

20. Once the lever height has been set, turn off the air supply

and purge the regulator. Remove the hose (25).

21. Install the o-ring on to the

venturi switch (9).

22. Install the venturi assem-

bly into the right side of

the box bottom (4). Lock

it in place by inserting

the retaining clip (7). You

should hear it “click” as it

locks into place.

23. Install the exhaust valve cover (11) by positioning the two

square holes in the cover over the mating two lugs on the

box bottom (4). Swing it up into position and engage the

latch. You should hear it “click” as it locks into place.

24. Fit the washer (2) on to the front of the diaphragm (3) and

place the assembly into the box bottom (4).

25. Fit the front cover (1) on to the box bottom (4) starting with

hose side. Visually inspect the cover to ensure that it is

seating evenly all the way around.
