8. Inspect the exposed floats for freedom of 13. With the hex wrench inserted until it will not go any <br /> movement or damage. These floats should slide further, the first stage valve flapper should stay in <br /> back and forth on the guide bar freely. If there the closed position. Using a flashlight, you can now <br /> is any binding, the guide bar may be bent. If see this by looking in from the top of the drop tube <br /> necessary, straighten this guide bar(see Figure D). (see Figure G). <br /> 9. Inspect the linkage connecting the floats to the <br /> valve operating mechanism. This linkage should be ` <br /> clean and intact(see Figure D). ' <br /> S� <br /> Figure D <br /> 10. Insert the 1/8"T-handled hex wrench into the open Figure G <br /> hole until it makes contact with the internal valve 14. Slide the second float away from the hex wrench <br /> flapper(see Figure E). (see Figure H).This will release the valve's second <br /> stage flapper(see Figure 1). <br /> Figure E <br /> i <br /> 11. While holding both floats from sliding away from <br /> the inserted hex wrench, lightly try to push the hex Figure H <br /> wrench further into the hole. The flapper should <br /> stay in the locked position and not move closed. <br /> If the flapper closes, the latching mechanism is <br /> defective and valve must be replaced. <br /> 12. Slide the float closest to the hex wrench away from <br /> the wrench.You should now be able to easily push <br /> the hex wrench further into the hole.This will close <br /> the first stage valve flapper(see Figure F). <br /> Figure I <br /> 15. Remove the hex wrench from the inspection port. <br /> The valve's internal flappers should return to their <br /> open positions.To verify that the flapper has reset <br /> and re-latched, re-insert the hex wrench and repeat <br /> Figure F Steps 10 & 11. If the flapper did not reset, replace <br /> the valve. <br /> 11 <br />
