i just bough a 20in homelite 46cc chainsaw from home depot. i am using it to take out a 40in diameter palm tree stump. the tree was originally 80ft tall but we had someone take it down to about 2 1/2 ft high. i have used a tiny electric chainsaw before but this thing is way out of my league. i want to know everything i should know when using this tool. i have heard about "kick back" (where the tip hits something and it shoots up at you) and when the chain gets jammed on the top and it shoots the chainsaw towards you, but have never experienced them so i don't know what i should be doing to prevent it. the saw has a tip guard on it, but after testing it for a min, i can see already i am going to need to take it off. if i get some replies in here ill post pics of what i have done so far, and what needs to be done. to be honest im scared. this thing is a beast. please give me anything, im reading the operators manual right now and its just making me think this is going to be very very dangerous. i am already telling my friends that help me and my family what to do if i get my foot or hand cut off.
