So... how many fire departments use battery powered chainsaws, roof saws, demo saws, etc? I know a lot have switched to battery powered jaws-of-life equipment (my department has begun using some). Most of our apparatus has at least one of each - chainsaw, roof (ventiliation) saw, and demo saw (K12 type circular saw). All (except one) 2 stroke gas powered. We have one battery powered K12 type saw. It is smaller than the traditional saws. Also, when people unfamiliar with it try to use it they inevitably push too had and jam/stop the blade, then complain about it. If you back off a bit and let it cut, it will go through almost any metal. Also, too many of our members are not really familiar with gas powered saws, so inevitably (not all the time, just seems that way sometimes) they will flood them when trying to start them. I was talking with someone about the saws, and he mentioned looking into battery saws. Realistically, for the amount we use them (especially the standard chain saws), that could solve a lot of the maintenance and use issues. They are usually smaller though, and in my experience have less power. Anyone here use chainsaws / roof saws that are battery powered in firefighting? Your thoughts?
