    I recently acquired a Jonsereds 630 chainsaw with an Electrolux motor. It runs like a champ and from what I've read on the forums here, it is well liked. I'm wondering if anyone has an owner's manual or service manual available? Or know where I could get one? I'm primarily interested in specifications both general and tune-up related. Any information regarding the spark plug, oil/gas mixture ratio, chain/lube etc. would be greatly appreciated. Thanks, Dave.

    The oil/gas mix is 50:1 on the 630. Search chainsaw collectors corner. There should tell you a lot about the 630. I have never got picky about bar oil. The cheaper the better. Its best to not let it run out of bar oil befor you add some more. Do a search on chainsaw repair manuals. Most I have seen included the Jonsereds.

    Thanks for the info, but about the gas mixture. Is it 50:1 or 32:1?

    WOW! Chainsaw Collectors Corner has got a lot of info. It appears to have the specs on the 630, however where do the specs come from? Any idea? The gas mixture listed there is 40:1. I'm guessing it's not that critical, but I thought it would have an affect on cold starting.

    I tried running mine at 40:1 and it fouls the plug after a week. I went back to 50:1 and go a long time in between plug changes. The owners manual calls for 50:1. Mine has worked well for 13 years at the 50:1 mix. I have never tried 32:1 but some people do and swear by it.

    My owners manual lumps the 625,630 and 670 all togather. It does not list a differance between any of these 3 saws on the gas mixture. If you can run richer then the 50:1 or 40:1 go for it. My 670 dont take to 40:1 at all.

    I like to hear long term results. Looks like I'm going to give the 50:1 a try. Any now that you mention plug fouling - maybe I should try a different ratio in my weedwacker.

    I would try the 40:1 first on the 630. If it dont foul the plug after a week or two stay with the 40:1 or richer if it will handle it as long as your not fouling the plug. I might try a synthetic oil and mix at 40:1 or 32:1 on my 670 but 40:1 on regular oil is a plug killer for me.

    I have not been able to locate Jonsered Operator manuals on the internet, but I think that the Husky one below will cover your need for an OM pretty good for general use and maintenance - at least it is the closest I am able to find.

    The Husky 61 and Jred 630 both shared the same fore-father - the Husky 162. Porting and carbs is most likely different, though - and the 630 has slightly more power than the 61.

    I was looking at some old papers from Jonsered. Here it clearly states the 630 was used in the last and this -84 sweden championship.

    Here is the good part.
    I found the prospect for it too. :)
    cc: 61,5
    weight: 7,2kg
    fuel: 0,7
    oil: 0,4

    A test driver for this saw in US was Ralf Levine
