12. NEW EQUIPMENT.
** ***
m. (Added). New gun may be received with valve spring removed from barrel and valve assembly. Spring comes tied to barrel. This is done to prevent strain on valve diaphragm assembly caused by pressure of spring in gun during storage and shipment. When weapon is being prepared for operation, spring must be untied from barrel and installed in gun, as described in paragraph 75.
n. (Added). Pressure regulator may be shipped at zero adjustment to prevent possibility of strain on diaphragm during shipment and storage. A regulator shipped in this condition has a tag (tied to the tank coupling) stating that the regulator is not set. When weapon is received in this condition, it must be adjusted as described in paragraph 67 before it can be operated.
*These changes supersede TB 3-376A-1, 19 October 1944.
