When it’s worn, the chain tilts. Check for wear of the guide bar opening. Before each use Worn bar needs to be repaired or replaced.

Most chain saw users will probably never need to use square ground chain, nor learn to perform square ground filing. But in areas where the timber is larger and the guide bars used are longer, the performance advantages of square-ground chain can outweigh the fact that square-ground filing is more difficult and much less forgiving of filing errors. FILE POSITIONING The file will sharpen the top plate, and the side plate, simultaneously. This creates a line, (A), where the top plate cutting angle meets the side-plate angle. For best results, file so that the line joins the cutting corner (B). SIDE VIEW END VIEW TOP VIEW FILE DIRECTION The chain manufacturer recommends that square-ground chain be filed from the outside in (in a downward direction). This leaves a better edge on the chromed cutting surfaces and makes it easier to keep the file’s position, and the resulting cutting edges, in correct alignment as shown in the preceding “File positioning” section. Filing from the outside in will wear out your file faster, however. Some square-ground chain users may prefer to file from the inside out (in an upward direction). You should be aware that inside- out filing is much more difficult. But whichever direction you choose, be sure your file and your cutting edges stay positioned as shown in the preceding “File positioning” section. File all cutters on one side of the chain, then reverse the chain and repeat the process. Use the same file positions for cutters on the opposite side of the chain. TOOLS Only use files specially designed for square-ground chisel cutters, available from your chain saw dealer.
