Improper or careless handling of the round can damage its components and cause the missile to malfunction when launched. If there is any reason to believe the missile has been damaged, the round must be returned to the responsible ammunition personnel for inspection and disposition. Before using the nightsight, the gunner must conduct a preoperational check IAW TM 9-1425-484-10.
a. Releasing the Bipod. Unsnap the bipod-retaining strap (A, Figure 2-2, page 2-3). Push the bipod forward until you feel resistance. Snap off the forward shock absorber. Ensure that the desiccant bag, attached to the forward shock absorber, is not lodged in the launch tube (B, Figure 2-2, page 2-3). While still holding the round, depress the bipod friction lock. Push the bipod legs downward to number 4 or 5, then release the friction lock (C, Figure 2-2, page 2-3).
b. Selecting a Firing Position. Select the firing position that best meets the situation. For training, use the sitting position (discussed later in this chapter). In a combat situation, you can use any one of the three positions: sitting, kneeling, or standing supported.
1. Do not use the shock absorbers as handles to lift the sight. The shock absorbers might tear off.
2. Do not touch the lenses, as this can easily damage them.
c. Removing the Sight from the Carrying Bag or Rucksack. Open the carrying bag or rucksack. Grasp the sight by the trigger mechanism or telescoping barrel. Remove the sight and remove the cover from the electrical connector. Secure the cover to the hook-pile tape on the forward shock absorber.
d. Removing the Lens Cover. Secure the lens cover to the top of the forward shock absorber (Figure 2-3). Visually inspect the lenses for damage or obstruction. When using the nightsight, make sure the ACTUATOR switch is in the ON position.
e. Mating the Sight to the Round. Place the sight guide pins in the slots of the sight bracket guide rails (Figure 2-4, page 2-4). This example uses the daysight, but you will use the same procedure for the nightsight. Use both hands and slide the sight firmly to the rear until the spring clip locks the guide pin in place (Figure 2-5, page 2-4). If the sight does not mate, notify your squad or section leader. Assume the firing position and put the round on your shoulder.
Avoid pressing the safety and the trigger while mating the sight to the round.
f. Adjusting for Height and a Level Sight Picture. Look through the sight to see if the sight picture is level. An unlevel sight picture (more than 6 degrees off level) will cause the sight to send bad commands to the missile. The missile will fly erratically and the missile will hit the ground. To obtain a level sight picture, adjust the bipod friction lock and the foot adjustment lever (Figure 2-6, page 2-5).
