The manual says not to use an extension cord.
Do you think if I brought an heavy duty cord, I could try?
I think if you look at most electric appliances, etc. they will say not to use an extension cord. I think it is more of a CYA then anything personally.
First thing to do is look at the appliance (or treadmill) data plate or manual. Look for the amperage rating. If it does not give amps, but does give watts, divide watts by 110 to get amps.
Then get an extension cord with an ampere rating at least 10% higher than what the machine draws.
Note the term "heavy duty" is meaningless. You need to know the actual numbers.
Extension cords, even those rated "heavy duty" are only for temporary use. Since it is a treadmill and is only "in use" for certain periods of time, I would not see a problem with it. I would, however, unplug it after use, and try not to run it for hours at a time.
Check the cord after you use it. If it is warm/hot to the touch, then it's probably not a good idea to continue with the extension cord.
Does anyone want to give an over/under on how many pages this thread could go to?
220, 221 - whatever it takes ....
