4. Procedure
_________
Subtask 32-41-00-210-061
A. Check of the Valve Indicator for Correct Operation
(1)
Put the tire inflation cart near the wheel on which you do the check.
(2)
Remove the tire inflation-valve cap.
(3)
Install the tire inflation adaptor and pressure gage on the tire
inflation valve. R
R NOTE : Use a pressure gage with the same accuracy as the pressure
____ R gage used in shop (scale: 0 to 300 PSI).
(4)
Lightly deflate the tire and make sure that the pointer of the valve moves.
(5)
On the indicator of the wheel inflation valve:
-make sure that the tire pressure indications agree with the pressure measured on the pressure gage.
NOTE : THE DIFFERENCE BETWEEN THE TWO INDICATIONS MUST BE EQUAL TO
____
PLUS OR MINUS 5 P.S.I.
(6) Inflate the tire again with nitrogen to the correct pressure (Ref. TASK 12-14-32-614-001).
