I have recently started to use a K380 I purchased a year or so ago to replace my K375. My problem is with the auto feeder that came with the unit new. it doesn't seem to work real well. the catalog number of the K380 is 87327. is there is way to adjust the auto feed for the smaller cable that came with the k380? the feeder seems to somewhat feed the cable forward a bit, but it doesn't put it back into the drum, weather it is in a drain or not?
