Electric chainsaw question..
« on: August 04, 2011, 04:24:44 PM »
Last spring I had a crabapple tree and some other bushes/shrubs that I wanted to get rid.So I bought one of those cheap yardworks electric chainsaws.Hey,I was surprized at how well it cut.The trunk of the apple tree was approx 9 inches in diameter and it went through it like a hot knife through butter.
So now I'm thinking that it would be great to take out camping just to cut a bit of firewood..My question is ...

Would a portable generator put out enough power to run it?
If so then what size generator should I get? Any ideas?

The saw is a 3hp - 12amp... 16 inch bar.

I've got a cheap little chinese 1000w 2 stroke generator, and it works to beat heck.  For what it cost me I keep waiting for it to blow up, and it just keeps humming along. 
It runs an electric impact wrench with no problem, so I'm certain it'll run your saw.  If you want, I can fire it up and try it, we've got a pole saw with an electric chainsaw on the end we could use.  (for another 40 bucks I could have bought the step up polesaw you could take the chainsaw off of, and boy am I kicking myself for that)

Anyway, I bought mine off ebay from a place in Van. about 5 years ago for 100 bucks shipped.  There's a place in Cal. that sells what I"m certain is the same thing in a different color with a different name on it for 139.00.  I'm actually thinking of buying one as a spare since we bought a little deepfreeze to take up N with us this year.  (2 trips cut short due to hanging meat and warm weather is enough!)
If you want the name of the store, just pm me.

Thanks for the info BruceW.
Looks like you don't really need a huge generator to run an electric chainsaw but I think 800 watts like in the video may be a little to under powered..
Perhaps a 1000 to 2000 watt one would be better.

I have an 1000 watt honda 4 stroke generator, and I reccomend that you go to atleast 2000.  1000's are good for charging cordless batteries, or lighting and small tools, but not much else.  If you get a 2000, you have way more versatility.  Spending a little more first is worth it in my opinion.  I have a 3000 EU Honda too, so that's why I didn't get a 2000.

X2 I have a 1000w that I recieved as a gift but would really suggest at least a 2000w. 1000w is not quite enough I find.

The saw is a 3hp - 12amp... 16 inch bar.
1000 watts = 8.3amps based on 115 volts ac.
2000 watts = 16.6 amps based on 120 volts ac.
  Household wattage is 1500 watts

Watts/volts ac ( 120 or 115 vac ) = amps ( current )
