I own a J5C09. I was just using the air compressor and as I was nearing the end/running out of charge, I noticed a small amount of smoke coming from the unit. I should probably note that I have used the unit ''mostly'' to inflate tires (as opposed to jump-starting). However, probably still less than a dozen times. Is my air compressor starting to die? If so is there any way to fix this, remedy or prevent it from happening?
