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.
