How To Sharpen A Chainsaw 🧐😎 To manually sharpen a chainsaw chain, use a round file appropriate for the chain size and a flat file for the depth gauge (raker), at an angle of about 25-35 degrees. Keep the engine off and the chain tensioned, then sharpen the saw blade with a pushing motion in one direction, always maintaining a consistent angle and amount of sharpening for all teeth. #fblifestyle #husqvarna #engine #chainsaw #stihl #motosierras #motorfúrész #kettensäge #tronçonneuse #chainsawma
