Hello Members, We are using .095 Diamond Edge trimmer line (the orange one). We are having problems with the string sticking inside the spools while sitting in our trailer. We have tried spraying silicone lubricant on the heads with little success. It seems the string is kind of melting together. If you take the spool out of the head, sometimes we cannot physically pull the string off the spool so naturally it will not dispense freely. This problem only happens on string sitting in the trimmers between yards etc. It does not happen with pre-filled spools sitting in the truck or while the string is still on the big spool. We have an open trailer and the string is exposed to the elements. We have been told to keep the string inside but our dispenser is mounted on the trailer and I don't really want it inside the truck. Any suggestions? Thank you in advance.
