I just lately got the Husqvarna top handle one, t536li or something close to that. No sooner than I get it home, did get a black friday discount I see they lowered the price from $470 to $400 on the website and guess what they figured mine at.
I put two pictures, the second one is how much firewood I could harvest from a logging left over place going from fully charged 4 lights steady to one light blinking which is discharged by the manual but still cuts. I can't say I notice it loosing power along the way.
They act like it is pro level. I put it with the clutch or sprocket cover removed next to a 338. Note they use the preferred method of one bar nut with the threads between two pins, well they cheated and the front pin is a plastic lump. The forces to clamp the bar go through the plastic clutch cover, the metal insert is up a bit so it won't make a mark on the bar like some brand x however the thickness of the plastic the threaded stud goes through is less than the thickness of the magnesium of the 338.
These things may be more safe than a gasoline chainsaw as I think it throws a circuit breaker in a kickback situation. I have at this point only used up three battery charges. The chain brake works wonderful and also turns off power to the motor. It needs the start button held for a second and it shuts off it seems in about a minute if unused so it may not really be any quicker into action than the 338 in real use. It is variable speed, kind a bit of strange hesitation as the trigger starts getting pulled, not sure if they all are going to be that way. The low speed perhaps is just how far along the variable speed it goes. Works pretty good on economy mode/low chain speed or whatever you want to call it when you push the second button which is instant and the second little light comes on.
It does have a parts sheet though the armature and what turns the oil pump and perhaps more is left out. The oil pick up is fixed not on a tube that is influenced by gravity. One oil filling according to the manual is good for three charges according to the manual. I have a 1/4 8 tooth sprocket on order. I have a good supply of 0.050 gauge 1/4 chain but it is likely one could adapt the 0.043 Stihl stuff, bar and chain that some on here like on the ms150. The bar mount is a095 small husky. The stock bar is made in USA at least the wrapper for the one I got says that.
My idea is to not scare the dog off when I am cutting pricker bushes, piling them on a tractor attachment and hauling them away. The dog has at times left when a gasoline chainsaw is started. I read the manual and it says not to use it to cut bushes.
