(_b_) Remove jammed cartridge through ejection slot by using hand ejector or cleaning rod as the case may be, and see that chamber is clear. (_c_) Withdraw the strip if some remedy is to be applied. Otherwise push it forward, bringing the next cartridge to the loading position. STOPPAGES AND THEIR REMEDIES. (1) =Jam on the first round of a strip.= The strip was probably not pushed completely home before trigger was pulled. Always push forward strip until pawl catches, so that both strip and cartridge are positively held in loading position. (2) =Missfire.= Eject defective cartridge by cocking gun, and continue firing. N.B.—A loose primer falling into the mechanism may cause repeated missfires. Dismount the piston and breech block so as to remove primer, which will usually be found either in the piston cams or in the fermeture nut near the entrance to the chamber. Missfires may be also due to a weakened recoil spring. In this case replace the spring with a spare. (3) =Bad introduction.= The cartridge jams at entrance to the chamber when being pushed forward by breech block. The bullet of the cartridge in question may have been imperfectly seated due to defective crimping, or the cartridge insufficiently held by the clips of the feed strip. In the latter case the strip should be put aside for re-sizing. Another cause of bad introduction is incomplete feeding due to lack of power. In this case screw up the regulator 3 to 10 divisions. (4) =Incomplete ejection of the spent cartridge case.= This is due to lack of power. Screw up the regulator 5 to 10 divisions. CLEANING AND CARE. This arm requires the same care as the service rifle. It must be kept clean and free from rust, and all parts lightly oiled. No gritty substances or emery should be used. As soon after firing as practicable the barrel should be thoroughly cleaned and oiled, particular attention being paid to the chamber. The gas cylinder should be kept free from fouling by means of the cleaner so that the regulator can be easily screwed up without using the dismounting wrench. When the gun is not in use the breech should be kept closed so as to avoid weakening the recoil spring. FEED STRIPS. The feed strips hold 30 rounds each. There are three rows of clips which hold the cartridge near the base, the middle and at the neck. A stop lug which catches behind the head of the cartridge case prevents longitudinal motion. FEED STRIP FILLING MACHINE. The feed strip filling machine is constructed for clamping to a bench or plank, as, for instance, the lid of a cartridge box. The hopper and clamp are removable for compactness in packing. The machine must be so placed that the crank can be conveniently turned with the right hand. Proceed as follows:— (_a_) Fill the hopper with cartridges.
