STEP 1
Ensure firing mechanism safety lever is in SAFE position, and charge lever is not in the CHARGE position before inserting or removing rocket or inserting spotting rifle magazine. Do not let muzzle of the launcher touch the ground during this operation. If muzzle should touch the ground, perform procedures on page 2-33.
WARNING
UP.
B. Remove a rocket from the backpack. STEP 2
The rocket encasement end cap, when in place on the rocket encasement, shunts the rocket motor igniter. This shunt prevents accidental rocket motor ignition due to electrical interference. When an unfired rocket is removed from the launcher for any reason, im- mediately replace the end cap. Failure to replace the end cap could result in accidental rocket motor ignition.
the other hand, remove the tape seal from the end cap/rocket encasement joint; then rotate the front end cap (2) 1/4 turn CCW. Remove end cap from round and place it on ground so the spotting rifle magazine is accessible.
A. Inspect the rocket as described in step 2 of PMCS, pages 2-8 and 2-9.
B. Insert rocket (1) into launcher (2) and rotate rocket CW approximately 1/4 turn until it locks in place.
If the muzzle of the launcher touches the ground, perform steps A and B.
Clear the SMAW before performing any maintenance procedures, checks, or inspections. Ensure that the spotting rifle chamber and magazine well are empty. See pages 2-54, 2-55, and 2-56, step 3A.
WARNING
A. Check inside the launch tube for dirt, rocks, or other foreign materials. If needed, clean as directed on page 3-19.
A. Remove spotting rifle magazine (1) from forward end cap (2).
B. Insert spotting rifle magazine (1) into the magazine well (3). Ensure spotting rifle magazine is locked in place.
C. To load and cock the spotting rifle, pull cocking handle (4) to the rear and release.

(1) DANGER AREA – No personnel allowed in this area; death or severe injury may be sustained from blast and flying debris.
(2) CAUTION AREA – Personnel must wear helmet, body armor, ballistic goggles, and hearing protection. (3) CAUTION AREA – Personnel should remain clear of this area. Injury may be sustained from flying debris
the rocket should hit them.
b. Fragments of the rocket which are formed by the detonation of the tactical rocket warhead can be hazardous to the gunner and other personnel on or close to the firing line. Ricocheting fragments of the practice and tracer cartridges can also pose a danger to personnel. The velocity of these fragments increase with target hardness. For safety reasons, the following minimum safe engagement ranges should be observed.
c. Rear Danger Area. Ensure no friendly troops are in Areas 1 or 3 and Area 1 (see page 2-36) is clear of obstructions and loose objects. Solid objects in the backblast area can deflect shock waves or debris toward the operator.
