Question: Is there a safety mechanism on this saw?  I've never used a saw like this--is it dangerous?
Document: The saw cuts very fast so you got to be more careful, as this trimmer is a little top heavy.I like this saw because the head tilts and the cutting head is streamlined.You can get into places the other saws can't.Compared this model to other pole saw designs, others are really electric chainsaws with a pole attached.The only complaint so far is the person who engineered this pole saw never used it once it left the design board! The way the on/off switch at the bottom of the handle was made... Well lets say it take some effort to push the safety button and on/off switch at the same time.
Well, I had some trees and bushes that needed some serious trimming that was beyond the capacity of my hedge trimmer. I could pay the landscape guy $500 (at least) or try it myself. I went for it. I assembled this unit and had a bit of trepidation, mainly due to safety concerns, having never used a chain saw before. I got it assembled and found there was a bit of a learning curve in terms of handling (definitely designed for a right-hander, which I'm not).
The saw was easy to assemble (and again, I've never used a chainsaw before). You'll need some chain/bar oil - $5 at home depot or you can order it from Amazon at a slightly higher price.Then the first problem... the screw cap for the oil wouldn't screw on. The screw thread on the housing had some residual plastic from the molding/manufacturing process, so the cap wouldn't catch. I debated returning it right there, but decided to try filing the screw threads down myself.
First, I've never used a chainsaw so factor that into how you interpret this review. Second, despite any negatives below, this is a really great saw. I needed something to clear some low hanging, small branches (&lt;10 foot away, and &lt;3 inch diameter) and wasn't in the mood to hire a professional (fees in my area were outrageous... in the thousands of $$$).Box arrived from amazon in two days and in good shape, as usual.
No real damage to the cord, but that plastic should have been rounded... -1/2 star.Then I took it outside. I was worried about handling this saw, seeing as I've never used one and I wouldn't consider myself particularly strong (about average, but probably less than average amongst chain saw users). When completely extended this saw is about 10 feet long, but when fully shortened comes in at about 5 feet. I had no problem with less than 7 feet length. 7-9 feet was tough but doable.
OK...these things need some balance.Someone, for safety sake and for exhaustion sake...please invent one of these with the motor behind the handle, and a flex drive up to the chain cutter...then you can hold it in the air for a long time...these are just plain dangerous and tiring. And the more you fatigue holding it up...the more tired you get...and more prone to a mistake.SO it cuts OK, but it is a real workout.
Wow! Cuts 6&#34; plus branches with ease. Lightweight, telescopes to a loooong length, and is easy to use. I've had mine for about a year and have used it for about 10 hours (off and on throughout the year) and it still looks and works like new. I saved over $1500. pruning my overgrown trees with this saw. I think it is the best buy on the market for pole saws.
My first use was to trim a branch that was exactly 10' away from a 3rd floor deck and 90 degrees straight out, so it was a challenge to get and hold the saw out there, but once in place worked like a charm.The chain rotates toward the downside -- like all chain saws I've used -- but you notice this helps as a pole saw. Place the blade where you want to start the cut (close the trunk), then the saw pulls &#34;down and into&#34; the cut.
I use this for Palm trees and this thing is by far the best tool I've ever used for trimming palm trees. This saw cuts through the green palm fawns like butter and it cuts through the hard dead brown ones like no one's business. I assembled the product using the included tools in about 15 mins and was outside cutting my palm trees in no time at all. I have several very tall palm trees in my yard and one was full of dead hanging hard brown frawns. This tool was cutting them off so fast I had to watch out for them falling so fast.I have no idea how this saw performs on other types of trees but for palm trees it is simply amazing and if you have ever cut palm trees you know how hard it can be to find any decent tools for the task and this saw will cut right up to the tree; no thorny thick stems sticking out anymore.The gardeners want way too much money for trimming now.
I will have to decide what to do next: keep it or try another saw. I've never had trouble with Amazon before, but this has me very disappointed.
