Filing out the gullet A File position fs and stroke (top view) .025 depth gauge setting B ?.K rlLuvCi FUWEH SHARP CHAIN Correct gullet shape .030 depth gauge setting File position and stroke (top view) This chain was designed so that 80% of the needed sharpening is accomplished by the saw's built-in sharpener. While the chain is being sharpened by the built-in sharpener, the cutting edges of the chain are gradually being altered. These edges may also be damaged if you saw into rock, dirt, nails, or other foreign materials. In either case, it will be necessary to reshape the side cutting edge with a file. To properly file the Power Sharp Chain you will need a fileholder and the correct size file. Follow these instructions: 1. If possible, remove the chain from the saw and put it in a saw chain filing vise. If you do not have a filing vise, tension the chain up snugly on the guide bar. Use a No. 5595 Fileholder and hold it level at a 24° angle to the chain. Always file from inside of chain toward the outside. 2. When cutters have been filed back to a point where the gullet (see fig. A ) extends beyond the cutting edge by 1/16 inch, the gullet should be removed. Do this before your next cutting edge filing, using the same 7/32- file and maintaining the same 24° Top Plate Angle. The correct gullet shape will then be as shown. 3. The factory Depth Gauge settings are .025 inch. The mark on the depth gauge (see fig. 8 ) is for setting of .030 inch. If you wish to use this setting, simply file off metal behind the mark with a round file as shown in figure 8 (see arrow). 1/32" 1/32" A Correctly Shaped Side Plate. (inside of cutter) 24 0 C A Correctly Shaped Top Plate Angle ... (top view of cutter) Remember: (a) Normal sharpening is accomplished by the built-in sharpener. (b) File cutters only when dull and attempt to keep all cutters the same length. The Side Plate should always be kept approx. 1/32- longer than the top plate (see fig. C). (c) Preserve the original filing angles carefully and uniformly. (d) Care should be taken never to file into the bottom of the Top Plate. a. 9
