Yeah Luk I love that saw. I also have a target that runs on 220 but it so much heavier, and I have to hard wire into the electric box in basement and carry my own breakers with me when I use it. Its a real pain in the butt. This say is great cuz I can carry it with one hand and I also take up on the scaffolding for doing the high gables. Easier on tender and faster than waiting.
I am not exactly sure what the freezing temp of mortar is. I figured 32 just like everything else since its made of water also. When the temp gets even close to that I carry a 100lb LP gas tank and a torch attachment to set on the drum of the mixer to heat it up while its mixin. Gettin it nice and warm is the key. Inside the tent its ok because with the heaters in there I work in a tshirt most of the time.
