Reassemble machine gun per TM 9-1005-313-10.
Check the overall machine gun and make sure black finish surfaces do not reflect light. Weapon with more than 1/3 of exterior finish worn off should be sent to depot for overhaul.
Check the tightness of all attaching screws, bolts, nuts, cotter pins, and rivets.
Check for adequate lubrication.
A machine gun that has been repaired should be function fired whenever possible to be sure it operates properly. If weapon cannot be function fired, use dummy rounds and function test manually. If a machine gun fails the function firing test, it must be reinspected to determine the cause of the failure and corrective action must be taken.
Upon completion of firing, machine gun must be cleaned and lubricated.
Make an overall inspection of the machine gun for cleanliness and general appearance.
This inspection is conducted on materiel in units alerted for overseas duty to be sure that such materiel will not become unserviceable in a relatively short time. It prescribes a higher percentage of remaining usable life in serviceable materiel to meet a specific need beyond minimum serviceability.
