When I bought my MS250 they sold me a Stihl sharpening kit with it. It’s a small flat file for the rakers, a round file with a guide and a gauge. The gauge I use for the rakers only. You set it on the chain and there is a place you can see if the raker is sticking up above the flat part of the gauge, they need filed. For me they rarely need it, maybe after 5 to 10 tanks of fuel.
