The sharpening stone looks like a really good way of introducing a highly efficient grinding paste to the drive sprocket and bearings when mixed with the inevitable bar oil that will be thrown around in there.

Good video Andy !

Thank you for the video and a glance at the internal hardware. I was curious at the insides so I could compare to the Makita 16 inch corded. This one is around 100 US dollars while the Makita is roughly 150 more. There's no direct comparison between the two I can find. I've only found one Makita repair video. These two are at the top of my list, im trying to justify the extra 150 into the Makita. Again thank you for the video.

Hi Andy. If a washing machine motor is rated at 350w for the spin phase it is hard to imagine this motor going over 2kw! I had a very decent cheap Lidl mitre box saw years ago. Chopped and chopped and chopped until the reduction gear stripped and that was that. No parts for these machines. There is an interesting trade off emerging. A machine like this that is buy use forget. No fixing ever. Maybe a warranty replacement. Or The device as a service. You buy a laptop/ car/ phone/ é scooter etc. you can’t replace any parts because they are all chipped and the device can recognise a non oem repair. Maybe for the bodger the cheap tat is more acceptable to paying a monthly subscription to use a chainsaw. It’s a natty oil pump. The irony is outstanding. You were in there in seconds and could have replaced any of the parts. But you can’t get replacement parts! Cheers from windy Ireland!

Andy, this is the same as a Qualcast, the brushes are available ( allegedly) from Oregon dealers , probl’y not in stock I don’t think other parts are stock able

Andy, the Kobalt brand 18" corded chainsaw that was available from Lowes has almost the exact same design in every way except motor orientation and of course voltage rating here in the US. I've had two burn out in the same fashion as yours. They are fantastic chainsaws when they run but they do not get adequate cooling and suffer from these design faults. In my opinion, either the brush holders' plastic have too low of a melting point (causing heat to rapidly increase as it warps/arcs), and/or the brushes are too soft. Additionally, I noticed a lot of the wire seems quite anemic for its 15 ampere rating on 120VAC. No idea why they thought giving it a 5 year warranty was a good idea, or offering 3 additional years for protection plans--but it is now no longer available for sale if that gives any indication of the failure. Because I love how this cuts I'm looking to replace the motor. Please let me know if you happen to find a source for these motors, I've checked many vacuum/blower brushed motor importers to no avail. On a side note, I don't mess with the self sharpening system at all.

Same thing happened to a worm drive skilsaw I brought from Canada, shame when a good tool goes down

hello and how the saw works how it works?

Isn't this the Oregon Power Sharp system? I always thought they had a special scabbard you put on and pushed it into a log which created lots of sparks to sharpen it.

Great

r there any electric corded chainsaws that are brushless?

All that arcing around the commutator does not look good, I agree Andy. Shame. I also don't like that sharpening stone - as Thornwarbler says, it's just a steel grinding paste generator. I don't understand the tooth shape at all, I've never seen anything like those. Plus the sharpener is going to miss the depth gauges completely so you'd still have to check those from time to time. I resurrected my incredibly basic Black and Decker saw from the 80s, after my Stihl saw of the same age was stolen, and I must say, for small use near to mains it's ideal - even though it's not very powerful and has no chain brake, so I have to be careful, luckily it's only a short bar. Cheers, Dave

Shame that , would of been handy as an emergency saw if you run out of 2 stroke etc etc etc .... you win some , you lose some .. on the note of self sharpening .... , I'd be intrested to hear if anyone thinks these type of systems work .cheers . .

Good try......never mind. Stick with a normal saw. Normal chain. Normal chain tensioner. Much safer. 👍👍😂😂. Great video. Thank you.
