Procedure Number 3, M732 Series, M728, and M514 Series Proximity VT Fures - Continued

To set the M732 series, M728, and M514 series fuzes for proximity action, rotate nose cone with the

M27 fuze setter, normally in a clockwise direction while looking down on the nose of the fuze, until the

index mark coincides with the announced time. The fuze setting can be changed one or more times with

no harmful effects.

For impact functioning set the M728 and M514 series fuze to 90 seconds and M732 series fuze on PD

mark using the M27 fuze setter.

The M732A2 fuze is set manually by alining the index mark on the movable aluminum setting ring (4) to

the desired setting as marked on the fuze sleeve.

To set the M732A2 fuze for proximity function, simultaneously depress the two locking pushbuttons on

the setting ring and rotate the setting ring to aline the index mark on the desired time setting. After

pushbuttons are released, the setting will be locked in place. This procedure may be repeated as

necessary.

For impact functioning of the M732A2 fuze, aline the index mark with the PD mark on the fuze sleeve.

Do not fire projectile unless fuze is fully seated. lnbore explosion may result, leading to injury or

death of personnel.

NOTE

Firing the M728 series fuze above charge 7 may result in excessive impact (PD) duds.

Firing temperature limits for M728 and M732 series proximity fuzes are -40 to 140°F (-40 to 60°C).
