I used my new Stihl Sniper KM 94 RC with pole pruner chainsaw attchemnet and I realized that chain became loose after using it ,,,,very enough I didn't have time to tension that and I stored for couple of weeks
Yesterday when I tried to use it again ,,,,,I have noticed chain is in not loose !!!!
Used it again and then after I finished I have noticed chain is loose again !!!!
Yes I know how to tension it ,,,,,but I don't know why that is happening ?
