Remove guide bar from chain saw. 2. Remove sawdust from guide bar groove periodically. Use putty knife or wire (see Figure 21). 3. Clean oil slots after each day of use. 4. Remove burrs from sides of guide bar. Use flat file to make side edges square. Replace guide bar when • bar is bent or cracked • inside groove of bar is badly worn Note: When replacing guide bar, see Replacement Parts and Accessories for proper bar. SHARPENING SAW CHAIN WARNING: Unplug chain saw from power source before servicing. Severe injury or death could occur from electrical shock or body contact with moving chain. WARNING: Cutting edges on chain are sharp. Use protective gloves when handling chain. Keep saw body clean. Use a soft cloth dampened with a mild soap and water mixture. Wipe saw body to clean. CARE OF GUIDE BAR Uneven bar wear causes most guide bar problems. Incorrect sharpening of chain cutter and depth gauge settings often cause this. When bar wears unevenly, it widens guide bar groove (see Figure 20). This causes chain clatter and rivet popping. Saw will not cut straight. Replace guide bar if this occurs. Inspect guide bar before sharpening chain. A worn or damaged guide bar is unsafe. A worn or damaged guide bar will damage chain. It will also make cutting harder. Guide Bar Groove Guide Bar Normal Guide Bar Guide Bar With Uneven Wear Figure 20 - Guide Bar Cross Section Showing Uneven Bar Wear 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.

Adjust chain for proper tension (see Saw Chain Tension Adjustment). 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 Figure 23). Note: File at midpoint of guide bar.

Hold file guide level. Make sure 30° mark on file guide is parallel to center of guide bar (see Figure 22). This will insure that you file cutters at 30° angle. 5. File from inside towards outside of cutter until sharp. Only file in this one direction (see Figure 22). 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. Filing Cutter Depth Gauges The cutter depth gauge clearance is reduced as cutters are sharpened. After every second or third sharpening, reset cutter depth gauges. 1. Place depth gauge tool (.025") firmly across top of two cutters. Make sure depth gauge enters slot in depth gauge tool (see Figure 24). 2. Use medium flat file. File depth gauge level with depth gauge tool. 3. Remove depth gauge tool. With flat file, round off front corner of cutter depth gauge (see Figure 25). After several hand filings, have authorized service center or sharpening service machine sharpen chain. This will insure even filing. Replacing Saw Chain Replace chain when cutters are too worn to sharpen or when chain breaks. Only use replacement chain noted in this manual. Always include new drive sprocket when replacing chain. This will maintain proper driving of chain. Note: For proper chain and drive sprocket, see Replacement Parts and Accessories.
