650 boards not that many cuts? Largest decking I ever made was about 140 m2 and ran around a house on three sides. That was large enough. Triple that? Ouch! I didn't have any problems with the KSS50 except I thought it a bit underwhelming for deeper rip cuts. I expected more grunt and closer to the performance of the KSS60 than the KSS40. Only good thing to come out of that was me being more pleased with the KSS40 and me getting the MT55 18bl instead. Except for the KSS40 acting up I am pleased with the set up and even sold my MT55cc as I honestly don't even need it anymore. The KSS50 I still think is more powerful and cuts better than Festool HKC55 - for both power and quality of cut. Still I think the HKC55 is a very good allrounder and I wish Mafell had that plunge set/lock that the Festool has. Not that many cuts in the sense that it's not enough to 'kill' the saw. (me, maybe!) It's 3x ski chalets at 120m² each - removal and replacement all on my own in 3 weeks - not bad going.
I may get a KSS50 at some point. I re-tried the KS18LTX57 today - OK for a couple of cuts, then stalling every few cm's. Made me regret selling the HKC55 which is a cracker!.. if the KSS50 is better, I'll be happy.

I’ve had my KSS40 for a couple months and it beeps at me a lot. Sometimes it’s just starting up the Saw to make a cut. There are a few times where I have to take off the battery and reattach to get the Saw working again. The last time it happened the battery was on a full charge. I did call Timberwolf Tools on it and they said they would check into it. Jeff called me back and said that he talked with Mafell and they think it has something to do with the batteries getting hot. Not sure I believe this is true bc the last deep episode it was the second cut of the day. I think my next step is going to be switching to only Metabo 5.5 batteries and see if the problem exists.

I use only 5.5 and 8.0 with the KSS40 - the smaller batts just don't cut it. Still beeps at me - temperature changes nothing.

I spoke at length with mafell today and apparently they have a workaround for the issue. New dust bags:  |

I might send mine in when it is 34 months old due to excessive beeping - at least get a service and check over before the warranty runs out.

Hmm, it does seem like there could be some overly sensitive on board electronics on the KSS 40.
Mine hasn't beeped in a while and I rarely work the batteries hot with the KSS40. But it is something to keep in check and it does put a dent in the confidence I have for Mafell. I hope they sort it out, I would hate to have to replace the saw every two/three years within or out of warranty. It is too expensive to have to suffer from faulty electronics.
Still love the saw to bits so keeping my fingers crossed!

To be fair, the 'only' dent in confidence for Mafell is the A10M (cordless) and the beeping KSS40 (cordless)... I hope this isn't the start of bad pattern - all the mains stuff is faultless... for now!

Being mafell I have to think of it as the end of these issues. They must be outsourcing engineering for their cordless electronics, sorta new for them, or they hired a decent in house guy/gal who’s on their own getting the finer details worked out. Either way I think it’s more of a learning curve and they’re getting up to speed. Could even be as specific as tuning algorithms or a supplier who’s already been replaced.

Yes, I believe marrying electronics to hard working hand tools is a path prone to hick ups and failures. I hope they will get on board with the electronics, literally!

I recently purchased kss40.Beep beep and puff dead. I sent it back. Turns out the motor fried. replaced and sent it back. Said it was a fluke... 2nd day on job after repair beep beep again and and shut down. Confused. It turned out that when battery is down to 2/bars it happened again. It seems to be regular thIng now. So I just swap it for a full one when it happens. Anybody else going through this? I really like this saw. Its real time saver. Real time saver.

The challenge with these newer tools is that there are so many "brains" in the works it's hard to trouble shoot. Is it the motor or the battery? Does it give you the bleep-bleep on both batteries when they get down to 2 bars, or just the one battery? It might be worth putting some masking tape on the batteries, marking them "A" and "B", and monitoring whether that condition manifests with both or just one? Which Ah batteries are you using? I can normally drain my Metabo 6.2Ah batteries down to zero. My KSS-40 was one of the very early units to come to North America. |

Pretty sure it happened on both. But I move so fast I could of had an oversight. I have a good thousand cut for it week so I'll have plenty of opportunities. |

Like dewalt flexvolt mitersaw led light blinks when it low.. |

Just logged in for the first time in a while, sorry to hear your KSS40 is acting up.
It is a bit of a mystery but I would start with the battery side of things. Any LiHD 5Ah or up should be fine.
I did get a new KSS40 in the end after my old unit was repaired and sold off and still I really enjoy using it but I don't have 100% confidence in it holding up long term. If it "weasel pops" again I would not buy a third unit.
For plunge sawing I bought back my corded MT55cc from my colleague and sold of my MT55 18bl (!). Part of me regrets selling the MT55 18bl but I don't use the plunge saw that often and sometimes when I do I usually work indoors anyway so corded works - and sometimes I use the KSS40 for that anyway.
