for a new learner I would definitily stay with the safety chain for a while. Yes it cuts a small amunt slower, but the danger of kickback with a newbie is IMO way too high. Even though 16 is fairly short, until you get that sense of where the tip is all the time, subconsciously in your peripheral vision, I'd stay with the REDUCED (not eliminated) kickback chain. You will lkely have one situation where you bump the tip and realize how easy it can happen. Don't let it scare you off, just learn.
goose: I see a huge difference between chipper rounded chain and chisel square corner, so I think that is way more difference than safety v. non safety. Cutting green ash, elm, or oak I use the chisel because it is faster nticeably. But if the bark is dusty or dirty, or dead hard dry wood, I go back to chipper becasue the chisel doesn't hold the edge as long.
I would also strongly recommend learning to touch up file the chain. Even couple tanks on chsel in hardwood, maybe 3 or 4 tanks on chipper. Even by changing chain often, you will be running much of the time on chain that is not really dull but is no longer razor sharp. Filing is not that tough, get a guide, the right diameter, see the angles of the tooth and understand what part works how. Get a depth gauge also to check the rakers/depth gauges occasionally.
I run quite long bars on small saws, (lot of limbing, whre the 026 20 inch shines) way over the 'rules of thumb', but I keep the chain razor sharp. Hit the dirt, stop and file it two or three strokes. Touch steel or rock, change the chain and have it ground. I want it pulling into the wood on its own and with weight of saw. if I have to force it even a small amount, the chain is dull. Yu will feel the difference the instant the tooth hits the wood.
A razor sharp chain also slightly reduced the chance of kickback-it can bite and cut even on the tip. Not a reason to be sloppy but it helps.
and personally, I'd run the 16, save the money. The difference is slightly important in power, and it is cheap enough to try for learning purposes or for your comfort level, but I'd put the money to PPE or the savings fund. At some point, you will want a larger saw, 50-60-70cc (or all of the above!)
sure it is a cheap homeowner saw, but even that is SO much better than what most of started out with, in speed, dafety, reliability, weight, and cost. I would have loved to have your saw when I started cutting.... I think at times the cheaper saws get ridiculed too much by bigger saws and even bigger egos.
utlimate, personal preferences, welcome aboard.
I really like the tagline f a guy on AS: Always remember your ltools are out to get you.
Not from fear, but healthy respect.
