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.
