This covers it all, from leaners to bars too small etc. even has the adjusted gun that many argue about. Rock Solid Stuff!
A credit to those who made it with great diagrams and covers the lot. I like it!
Also just added the NZ guide, also great with some good cross cutting (bucking) tips, go the Kiwi's.
Another addition, Power Point file, about 3.25mb very good by OSHA USA
