To Dismount Completely.—1. Turn the barrels until the arrow on the rear assembling-disk marked "Dismount" is opposite the arrow on the right upper quarter of breech-piece.
2. Enter a punch in the hole in the breech-piece and back out the keep-bolt of the pin-wheel.
3. Unscrew and take out the pin-wheel.
4. Unscrew the four bolts which secure the frame to the breech-piece.
5. Slip the breech-piece off to the rear.
6. Remove the group of barrels from the frame.
Mounting is done in the inverse order. Start the pin-wheel on before pushing the breech-piece entirely into place. In driving in the keep-pin of the pin-wheel be careful that it is close home so as not to grind in the journal. Also, before dropping the keep-pin in turn the barrels until the arrow marked "Mount" is opposite the one on the breech-piece.
CARE AND CLEANING REQUIRED.
Apply the rules given for mountain-artillery, page 4.
In scrubbing out the barrels it is always best to turn the one to be scrubbed to the extractor-hole, as this position gives the most room for thorough work and the water does not slop into the breech-piece. Elevate the gun slightly and put the water-bucket under the extractor-hole.
