Well this year is my first time ever cutting wood and I have had the end sprocket get jammed up 4 times now since cutting about 4 cords of wood in the last couple of months. I always manage to get it unstuck but it usually takes me quit some time to clean out the wood chips that are jamming it. Just wondering if this is a common thing or am I doing something wrong maybee my chain is to tight or or something Im not sure. All i know is its frustrating and a big waste of time to go back to the truck and take off the chain to try and free up the sprocket. Any tips from you more experienced cutters would be helpful.
