SAFETY INFORMATION 

WARNING 

Be sure to clear weapon before starting inspection. 

If cover is opened on a fiot cartridge (hot ban-el), an open-cover cookoff could occur and result in 
serious Injury or death. Evacuate area for 1 5 minutes and then do IMMEDIATE ACTION. Refer to 
page 2-35. 

Never reload a runaway machine gun until it has been repaired. Be sure machine gun is cleared 
before moving it. 

When removing a stuck unfired cartridge, stay clear of the muzzle. Do not allow cartridge to 
contact any hard surface. Cartridge may fire on contact. Remove a stuck unfired cartridge using 
the same procedures for removing a stuck or ruptured cartridge case. 

Before field stripping check that the bolt is in forward position. 

Bolt assembly is under spring tension; it can twist and injure your hand. 

Barrels issued for a specific gun will not be changed from gun to gun. Each ban-el and bolt 
assembly should be tagged during cleaning with the serial number of the receiver (gun) and 
should remain together as initially assigned. Interchanging ban-els may result in injury or death. 
Insert the hinge pin from one side and the hinge pin latch from the opposite side. 
After unloading dummy round, be sure the barrel Is cleared. 
Ammunition to be used in machine gun is authorized in Chapter 5. 



SAFETY INFORMATION (CONT) 

WARNING 

Keep weapon pointed at target - down range/impact area. 

Keep safety on S until you're ready to fire. 

Always check the chamber/bore after clearing the weapon. 

Checl( barrel bore and chamber before firing. 

Do not interchange bolt assemblies or components from one weapon to another. This may cause 
injury or death to personnel. 

Change f|ot barrels with your heat protective mitten only or by holding bipod legs. (Refer to page 
3-5 for additional hot barrel procedures.) 

Do not interchange leaf springs from one model weapon to another. 

Check that assigned and spare barrels have been headspaced and tagged to your receiver 
Rotate usage of the ban-els. »» 7 

Firing Blank Cartridges 

Do not fire blank ammunition toward personnel within 20 feet of the muzzle. Fragments of a ckjsure 
wad or particles of unbumed propellant might inflict injury within that range.

GENERAL 

Always keep in mind the CAUTIONS and WARNINGS when performing your before (B) or during 

(D) PMCS. The numbers in the item number column shall be used for the "TM Number" column on 

DA Fomn 2404, Equipment Inspection and Maintenance Worksheet, in recording results of PMCS. 

After you operate, perform your after (A) PMCS. 

Perfomn BEFORE PMCS if: (1) you are the assigned operator and the machine gun has been 

stored and not used for a period of 90 days or (2) you have been issued the machine gun for the firs 

time. 

WARNING 

DO NOT INTERCHANGE BARREL ASSEMBLY OR BOLT ASSEMBLY FROM ONE 
MACHINE GUN TO ANOTHER. DOING SO MAY RESULT IN INJURY OR DEATH.

Section IV. OPERATION UNDER UNUSUAL CONDITIONS 

PROTECTIVE MEASURES FOR UNUSUAL CONDITIONS 




In Extremely Cold Climate: Lubricate according to Lube Guide (p 3-0). Use CLP lightly and 
keep weapon free of moisture. 



2-43 



PROTECTIVE MEASURES FOR UNUSUAL CONDITIONS (CONT) 

In Hot, Wet Climate: Lubricate and inspect at least twice monthly. Use light coat of CLP and 
keep weapon dry. 

In Hot, Dusty, and Sandy Areas: Inspect daily and clean frequently. Wipe CLP from exposed 
surfaces and keep sand out of parts. Cover weapon as much as possible. 

After Exposure to Water: First make sure weapon is dry before lubricating. Then disassemble, 
clean, lubricate, and reassemble weapon as soon as possible.

DATA SECTION (DETAILED LEGEND) FOR RANGE CARD 

Purpose of the Range Card and Data Section: To prerecord information on various targets to 
use during limited visibility or to adjust fire rapidly. 

Target Numbers (Reference Numbers): Indicate reference points in field of fire. 

Information on Eacfi Target includes: 

• Target description. 

• Range to target. 

• Elevation setting on traversing and elevating mechanism to hit target. 

• Deflection setting on traversing and elevating mechanism to hit target. 

• Any pertinent remarks. 

Reference: FM 23-67 



2-45 



PREPARING A RANGE CARD 

In a defensive situation, make a range card. The essential elements of the range card are: 

1 A known Reference Point (RP). 

2 The direction and distance from the RP to the machine gun. 

3 The machine gun position. 

4A The sector of fire with left and right limits (in this case, also Final Protective Line, FPL). 

4B Secondary sector. 

5 The MAGnetic AZimuth (MAG AZ) of the FPL. 

6 Dead space in the FPL where there is no grazing fire. 

7 Reference points (target numbers) within the sector of fire (7A thru 7F). 

8 Magnetic north. 

9 Gun unit and date. 

A detailed legend or data section will accompany the range card. See page 2-45.

CHAPTER 5 
AMMUNITION 



WARNING 

This is the only ammunitJon authorized for use in your machine gun. If it is not shown, it 
is not authorized. 

AMMUNITION WHICH FAILS TO FIRE. Dispose of any ammunition, which fails to fire, 

according to authorized procedures.

CARE, HANDLING, AND PRESERVATION. 

a. Do not open ammunition containers until the ammunition is to be used. Ammunition 
removed from the airtight containers, particularly in damp climates, is likely to corrode. 

b. Protect ammunition from mud, dirt, and water. If the ammunition gets wet or dirty , wipe it off 
prior to use. Wipe off light con'osion as soon as it is discovered. Heavily corroded cartridges or 
cartridges which have dented cases or loose projectiles should not be fired. 

c. Do not expose ammunition to the direct rays of the sun. If the powder is hot, excessive 
pressure may be developed when the gun is fired. 

d. Do not oil or grease ammunition. Dust and other abrasives collecting on oiled or greased 
ammunition will damage the operating parts of the gun, and oil on cartridges will produce 
excessive chamber pressure.
