Don't panic Dave Smith, the new bit is the 40volt battery operation, I have had a conventional 2stroke powered chainsaw for over 40years - not the same one... Very pleased with the results.
I use an extremely sturdy metal saw bench with a pivoting clamp and shield arrangement to which the saw is attached, becoming a sort of chop saw. Freehand chainsawing is avoided.
Splitting is no longer done with a maul (wide axe) after a bit flew up and whacked me on the head, a 5ton electro-pneumatic splitter was bought a few years ago with the winter fuel allowance. Highly recommended.
Meanwhile, back in church, rough area Diapason?
