WARNING
Before removing the foot control cover, turn the air supply OFF and
bleed all pressure from the system. If this is not done, the stem
assembly may be ejected from the foot control valve. Never turn the air
supply to the foot control ON when the cover is off of the foot control,
unless appropriate steps have been taken to ensure that the stem
assembly cannot be ejected.
(1)
Remove the foot control cover.
(2) Use a soap solution, if necessary, to locate the source of the leakage.
The leak will bubble when you coat the area where the leak is occurring with a heavy
soap-water solution.
