1. Press the spring-catch and open the cover. 2. Remove the feed-box by lifting it up out of the gun-frame. 3. Remove the lock; to do this, turn the crank-handle, which brings back the lock from the barrel, and disengage it from the guides; now let the crank-handle go slowly backwards and at the same time lift the lock upwards; the lock will rise, and when in this position one eighth of a turn will detach its divided screw from the threads on the connecting-rod, when it can be lifted out. 4. Press the spring-box forward and lift the three lugs out of their respective pins, then disengage the spring from the chain and remove the box with the spring. 5. Drive out the pin, and remove the double-button lever with the spring and cup. 6. Drive out the handle-block pin; start the handle-block by slight blows with a mallet or piece of wood from beneath, lift it out of the gun-frame, and remove the rod. 7. Remove the two small slides by sliding them back out of the gun-frame. 8. Draw the recoiling-frame with barrel out from the gun-frame and water-jacket. INSTRUCTIONS FOR ASSEMBLING. 1. Replace the barrel and recoiling-frame. 2. Replace the two small slides. 3. Replace the rod and put the handle-block in the gun-frame; see that the rod enters its seat in the handle-block before driving the block home, and put in the pin. 4. Engage the double-button lever with the rod, and replace the lever, spring, and cup, and put in the pin. 5. Engage the spring with the chain not wound around the fusee and replace the spring-box. 6. Replace the lock by screwing it into the connecting-rod until the two shoulders meet, then turn the crank-handle forward, guide lock into its guides, and let the crank-handle go slowly back to its place. 7. Replace the feed-box, with the stud in its seat, in the recoil-frame. 8. Close the cover by pressing the spring-catch. TO DISMOUNT THE LOCK. (See Fig. 101.) All pins enter from right to left. In driving out a pin see that the side of the lock round the pin is well supported. See that the carrier is in its highest position; then release the mainspring by lifting the safety-sear and pulling the trigger. 1. Take out the pin (1) which secures the mainspring and the clip which keeps the carrier-levers in their places. Remove the mainspring, clip, and carrier-levers. 2. Take out the pin (2) that secures the sear. Remove the sear. 3. Drift out the pin (3) that secures the hammer. Remove the hammer. 4. Drift out the tapered pin (4) that secures the safety-sear. Remove the safety-sear and the firing-pin. 5. Take out the pin (5) that secures the piece which regulates the downward position of the carrier and keeps the carrier in its place. Remove piece and carrier. 6. Remove the cover (6) at the back of the carrier and take out the upper piece and spring; the lower piece is riveted onto the carrier.
