A file holder must always be used for manual sharpening of RapidSuper and Topic-Super chains. File evenly and steadily and note that the file only sharpens on the forward stroke. The file must be lifted off the cutter on the backstroke. Make sure that you do not touch the tie straps and drive links. Burrs on the cutting edge can be removed with a piece of hardwood. Rotate the file at frequent intervals in Order to prevent it becoming worn unevenly. Important: Sharpen the chain frequently and take away as little material as possible. Two or three strokes of the file are usually sufficient to Ikeep the chain sharp. A STIHL electric sharpener greatly simplifies chain shar- pening. 33

The file must be lifted
