N Always file from the inside to the outside of the cutter. N The file only sharpens on the forward stroke – lift the file off the cutter on the backstroke.

Tools"). The correct filing angles are marked on the file holder. All cutters must be the same length. MS 362 49 English If the cutters are not the same length, they will have different heights. This makes the chain run roughly and can cause it to break. NFind the shortest cutter and then file all other cutters back to the same length. It is best to have this work done in the workshop on an electric grinder. Depth gauge setting Lowering depth gauges The depth gauge setting is reduced when the chain is sharpened. NUse a filing gauge to check the setting every time you sharpen the chain. NPlace a filing gauge (1) that matches the chain pitch on the chain and press it against the cutter – if the depth gauge projects from the filing gauge, the depth gauge has to be lowered. NFile the top of the depth gauge parallel to the stamped service marking (see arrow) – but do not lower the highest point of the depth gauge in this process. NPlace the filing gauge on the chain – the highest point of the depth gauge must be level with the filing gauge.
