Check out this guys video part 1 and 2 on Youtube its not in English but it will show you how to strip a Sumatra down google DESMONTANDO SUMATRA PARTE I Youtube.Very good video
I just received a DVD on the 707 teardown which would also work for the Sumatra with just a few differences. I found it on Ebay and it only cost me $11.00 shipped. I received it in about 10 days which wasn't too bad. I watched about half of it so far and it is well made and easy to follow. Also he speaks English but with a British accent.
Welcome to GTA Andrew. I've got a .25 Sumatra carbine too. Great airgun!
Welcome to the GTA Andrew, enjoy the Sumatra.Merry Christmas.Dave
Welcome to the GTA Andrew! Merry Christmas to you!
RavenHunter, welcome aboard!!!! Merry Christmas, Happy New Year to you and your family!!! You now own a great little carbine!!! The Sumatra Carbine both in .22 and .25 are so nice to handle and accurate. If her bark is a little loud Neil Clauge or Anthony Storey make a great LDC for her. These little guns are my faves for hunting! Remember that you can adjust your power as your poi drops. Gives you a few more spot on shots!! Well, Enjoy your carbine and once again welcome to GTA. Take Care Brother Man
I'm saving up for a Sumatra Carbine now. Can't wait. Congrats!
