Flat File Cleaning Groove Burr With Putty Knife Oil Slot Guide Bar Figure 18 - Guide Bar Maintenance SHARPENING YOUR 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 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. Items Needed to Sharpen Chain Purchase these items from your local dealer, hardware store, or chain saw supplies outlet. • 4 mm (5/32") round file • File guide • Medium sized flat file • Depth gauge too • Vise Sharpening Cutters Use file guide for 30° filing. 1. Adjust chain for proper tension (see Saw Chain Tension Adjustment, page 8). 2. Clamp guide bar in vise to hold saw steady. Note: Do not clamp chain. 3. Press four millimeter (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 cutter until sharp. Only file in this one direction (see Figure 19). Note:Two or three strokes with file should sharpen cutter. 6. After each cutter if 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. FILE HOLDER 30° Guide Mark File Guide 4 mm (5/32") Round File Note:This illustration shows file guide placement and filing direction for sharpening cutters on left side of chain.

After every second or third sharpening, reset cutter depth gauges. 1. Place depth gauge tool firmly across top of two cutters. Make sure depth gauge enters slot in depth gauge tool (see Figure 21). 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 22). Flat File Depth Gauge Depth Gauge Depth Gauge Slot Tool Figure 21 - Depth Gauge Tool On Chain Front Corner 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. STORAGE If storing saw for more than 30 days, follow steps below. 1. Drain oil tank. 2. Remove and clean guide bar and chain. Clean guide bar and chain by soaking in petroleum based solvent or mild soap and water mixture. 3. Dry guide bar and chain. 4. Place chain in container filled with oil. This will prevent rust. 5. Wipe a thin coating of oil over surface of guide bar. 6. Wipe off outside of saw body. Do this with soft cloth dampened with a mild soap and water mixture. 7. Store chain saw • in a high or locked place, out of children’s reach • in a dry place • in a carrying case or with scabbard over guide bar • with oil cap tight and saw upside down to prevent excess oil seepage REPLACEMENT PARTS WARNING: Use only replacement parts described in this manual. Use of other parts could damage saw or injure operator. Purchase these parts...
