Is anyone using the chain mortiser on a generator I have the 240volt version which I need to run on a generator as I am without mains power. In order to purchase the right size generator I need to know the approximate peak watts that is drawn by the 103 at startup. Does anyone have any idea or has anyone run one on a generator and if so what size? Thnks

Best to ask a generator seller... as a guide, it's something like : Generator KVA = 3 to 3.5 x motor kw So for the LS103 (2.5kw) you'll need a 7.5 to 8.75 KVA generator.
I used to run an induction motor table saw off a generator, had to hold the NVR switch in on the table saw for 20 seconds until it got up to speed. it was OK when running, but neither machines liked starting.

Thanks, Tried asking the tool seller what the startup draw is but unfortunately I don’t think they completely understood the problem because their answer was that the startup draw was LOWER than the continuous operating draw. I’ve never heard of that being the case. Everything if seen written is that it ranges from double the continuos operation to 5 times, and that you need to find out about your specific machine. I have asked Mafell.de by email but haven’t heard back at this stage. Unfortunately we have no Mafell dealer in Australia so I can’t walk in and ask. The other issue is getting a good clean sine wave from the generator I know that I can do that with a Honda up to about 7.5kva but above that takes me into a whole different realm of generators pretty much

I’ve added a Honda EU-3000is HANDI to my daily carry in the van and love it, particularly on older Minneapolis homes where they frequently don’t have outlets on the outside of the home. For high draw scenarios I link a pair of the EU-3000 generators and they seem to be able to tackle anything I throw at them. They start my Erika 70 just fine, which is rated at 2200 watts.
I think you’re on the right path looking at a Honda EU-7000. That would get you a nice clean sine wave, and should give you enough oomph (that’s a technical term) to get your machine running. Like you said, anything larger than that and you’re in a different world of generator.
Is there a local Honda dealership that would let you plug in your LS103 to see if the generator can keep up?
