I’ve ended up using my little 30cc Echo th more than big saws in the last few years. Trimming oversized firewood chunks, landscape timbers, cutting up pallets, and as main trail/backpack saw for clearing motorcycle trails.
I don’t climb trees.
1. I run low kickback safety chain, because I am in a lot of brush usually.
2. 12 inch bar
3. REALLY cautious, bordering on always fearful, of a one handle potential, and keeping bar way off to my right side.
4. Because of the way they are carried, hand on the handle and index finger on the trottle, I had one time a foot slip and hand reaction was grab tight, and wot. No injuries, but realized I could have fallen face down onto that thing. So I added an aluminum bracket under front of the handle, so my index finger is on that stationary bracket, and I run throttle with second finger. Its also how I run electric drills. Better grip with thumb and index, then switch or throttle control with second finger.
I have no idea if it has made any difference in my safety, but seems to make my grip different and more steady.
