1) Remove the screws and washers on either side of

the regulator cover.

2) Unscrew the cover retaining ring.

3) Remove the cover and diaphragm. Inspect the

diaphragm for holes or tears. If it torn or punctured it

must be replaced. Inspect the interior of the regulator

for foreign matter and remove if necessary.

4) Carefully insert the tip of a flat blade screwdriver

in the slot at the top of the lock clip and slide the clip

away from the regulator main tube.

5) Using the 1” open end wrench, loosen the pack-

ing nut about 1 turn. While depressing the lever arm,

grasp the flex knob and pull it straight away from

the regulator body. This will remove all of the main

components of the regulator valve mechanism as a

single, easy to handle unit.

6) Unscrew the flex knob assembly from the main

tube.

7) Loosen the packing nut on the flex knob and un-

screw the packing nut. Hold the packing nut while

turning the flex knob clockwise. You will notice the

internal adjustment shaft will travel outward AWAY

from the packing nut.

This shaft may not fall out so after about 10 revo-

lutions of the knob. It will be possible to grab the

chamfered tip of the shaft and pull it straight out

from the assembly.

Remove the cover retaining ring and regulator

cover.

Remove the lock clip from the interior of the

regulator.

Unscrew the packing nut from the regulator body.
