Within the limits of the magazine capacity the gun continues to fire so long as the trigger is held back, and stops firing whenever the trigger is released. Full Automatic Fire. Continued pressure on the trigger results in full automatic fire, which need be interrupted only by the four seconds interval required to replace emptied magazines by loaded ones. During firing, before the magazine has been emptied, the gun stops at the beginning of the forward stroke, in the “ready to feed” position. In this position the action is open and the chamber empty, but firing can be resumed on pulling the trigger. General Note. =Before Firing.=—See to it that bore is clear, working parts properly lubricated, and that tension of main spring is sufficient to avoid missfires. =After Firing.=—See that gun is immediately unloaded, and that bore, working parts, and bearing surfaces are carefully examined, cleaned, and properly lubricated as soon as possible. It is especially important to oil piston head and inside of gas cylinder; and to remove oil, and replace gas regulator cup. Burrs found raised on any working part should be removed, and any roughening on a bearing surface should be smoothed down with fine emery or an oilstone. TO STRIP AND ASSEMBLE. The gun may be taken apart starting with the mechanism in any position, but it is best, whenever practicable, to see that the magazine is removed, the chamber empty, and the charging handle at the extreme forward end of its stroke, before commencing to dissemble. If this procedure is followed there will be no need to readjust the mainspring tension or to make any other adjustment when the gun is reassembled. Stripping. To dissemble gun, insert point of a bullet into slot leading to butt latch and push forward against force of butt latch spring. At the same time twist buttstock up and to left, then remove by withdrawing it to the rear. This removes buttstock group which should not be further dissembled. Next, hold back trigger and pull back guard until clear of receiver. This removes guard, which contains trigger mechanism and butt latch. Pull down gear casing until it drops clear of rack. Pull back charging handle until it reaches end of slot, then withdraw by pulling it out away from receiver. Withdraw operating rod complete and bolt complete by pulling them both together to rear until clear of receiver. With point of a bullet push back on receiver lock pin, then twist receiver up and to left and unscrew it from barrel. The foregoing operations divide the gun into convenient groups. DETAILED STRIPPING. Buttstock Group. It is best never to strip this group, but if found necessary, the screws securing buttplate and butt tang to buttstock are readily removed. Receiver Group. See that the feed operating arm is pushed to the right, then pull back and remove feed cover.
