SHARPENING SAW CHAIN

WARNING: Unplug chain saw from power source before servic- ing. Severe injury or death could occur from electrical shock or body contact with moving chain.

Sharpening Cutters

Use file guide for 30° filing.

1.Adjust chain for proper tension (see Saw Chain Tension Adjustment, page 7).

2.Clamp guide bar in vise to hold saw steady. Note: Do not clamp chain.

3.Press 5/32" round file (attached to file guide) into groove between top plate and depth gauge on chain. File guide should rest on both top plate and depth gauge (see Figures 19 and 20). Note: File at midpoint of guide bar.

4.Hold file guide level. Make sure 30° mark on file guide is parallel to center of guide bar (see Figure 19). This will insure that you file cutters at 30° angle.

5.File from inside towards outside of cut- ter until sharp. Only file in this one direc- tion (see Figure 19). Note: Two or three strokes with file should sharpen cutter.

6.After each cutter is sharpened, move chain forward to sharpen next cutter. File all cutters on one side of chain.

7.Move to other side of chain and repeat process.

WARNING: Cutting edges on chain are sharp. Use protective gloves when handling chain.

Keep chain sharp. Your saw will cut faster and more safely. A dull chain will cause undue sprocket, guide bar, chain, and motor wear. If you must force chain into wood and cutting creates only sawdust with few large chips, chain is dull.
