I bought an electric chainsaw for cutting firewood, was told it's a lot less hassle maintenance wise.
The thing scares me slightly. As someone said previously, it would be easy for a life changing event to happen whilst using one of these things.
I drive a cab, a fella told me a story about how he was going back to the west country to visit his friends family because the father, that he remembered using chainsaws for 30 years had been cutting a fallen tree and the thing sprung over and crushed him. Sounded awful. I suppose the energy stored in this fallen tree was like a 3 ton spring.
I've bought a cordless reciprocating saw as well, i use this 90% of the time
