OD: welcome to the forum from a neighbor across the water. i don't have the Snappy answer for you, but might i suggest doing a search either in General tools section or do a google search and in most cases they will have a GJ link near or at the top to click on that might bring up some older threads that are not easily found on GJ's search engine.
good luck and if you do find threads talking about your Snap on and you don't find your answer ask a question on that thread where you have members talking about it instead of this intro thread where not many members even know it's here.
cheers
