3rd.— Remove guard. 4th.— Withdraw recoil spring. 5th.— Remove recoiling mechanism. Replace defective part by a spare, and mount by reversing operations. The extractor and extractor spring can also be removed without stripping gun as follows:— 1st.— Insert an empty cartridge case in the ejection slot, perpendicular to chamber. 2nd.— Close breech gently, i.e., by holding it back with cocking handle, on to empty cartridge case, thus giving access to extractor and extractor spring. 3rd.— Remove extractor spring and extractor by means of hand extractor. Replace defective part by a spare, cock the gun and withdraw empty cartridge case. POINTS TO BE ATTENDED TO BEFORE FIRING. 1. Cock gun. 2. Pass cleaning rod down the bore to make sure that barrel is clear. 3. See that regulators of all available barrels are properly set. 4. Oil mechanism. A moderate quantity of oil will suffice. It is useless to flood the mechanism. As the essential parts are sufficiently accessible through the ejection slot and by opening the feed piece cover, dismounting is not necessary. 5. Test action of both ejector and cartridge stop by pushing on their points. They should work freely, their springs being elastic but without stiffness. 6. Test action of mechanism by rapidly opening and closing breech several times. It should work freely and smoothly. OPERATING THE GUN. In firing, the prone position will be taken ordinarily, the barrel rest being used to steady the gun. In high grass or under conditions where more height is desirable, ammunition boxes may be placed under the barrel rest so as to increase height. In short, any sort of rest available may be used, for instance, the top of a parapet or the limb of a tree. In going into action the following operations must be performed:— (1) Set barrel rest. (_a_) Free legs from their catches. (_b_) Turn legs forward until at right angles to barrel. (_c_) Open legs with a sharp movement such that the separators catch in one another. (_d_) Place the feet in desired position and force points into the ground. (2) Mount elevating mechanism. (_a_) Place elevating mechanism foot on ground in such position that it is at right angles to axis of gun. (_b_) Bring gun to approximately the required elevation by turning outer elevating screw. (3) Take firing position. (_a_) Take prone position, resting on the elbows. (_b_) Grasp pistol grip and trigger with right hand, pressing stock well into hollow of right shoulder. (_c_) Grasp outer elevating screw with left hand. (_d_) In case elevating gear is not used, left hand grasps stock to rear of receiver and pulls shoulder strap down solidly against shoulder. (4) Cock gun. (_a_) Throw cocking handle knob to left to a stop.
