1st Cut 2nd Cut Figure 16 - Bucking Log When Log Is Supported On Both Ends TRIMMING A TREE (Pruning) WARNING: Avoid kickback. Kickback can result in severe injury or death. See Kickback, page 3 to avoid risk of kickback. Trimming a tree is the process of cutting limbs from a living tree. Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet. Follow directions below to trim a tree. 1. Make first cut six inches from tree trunk on underside of limb. Use top of guide bar to make this cut. Cut 1/3 through diameter of limb (see Figure 17). 2. Move two to four inches farther out on limb. Make second cut from above limb. Continue cut until you cut limb off. 3. Make third cut as close to tree trunk as possible on underside of limb stub. Use top of guide bar to make this cut. Cut 1/3 through diameter of stub. 4. Make fourth cut directly above third cut. Cut down to meet third cut. This will remove limb stub. WARNING: Do not operate chain saw while • in a tree • on a ladder or any other unstable surface • in any awkward position You may lose control of saw causing severe injury. WARNING: Do not cut limbs higher than your shoulders. CAUTION: Seek professional help if facing conditions beyond your ability. 2nd Cut Pruning Cut 4th Cut (to avoid pinching) Final Stub 2" to 4" 6" 1st Cut - Pruning Undercut (to avoid splintering) 3rd Cut - Stub Undercut (to avoid splintering) Cut Figure 17 - Cutting A Limb 097017 11 ® ® ELECTRIC CHAIN SAW CLEANING AND MAINTENANCE NOTICE: Below are instructions for servicing your chain saw. Any servicing not mentioned below should be done by an authorized service center. CLEANING SAW BODY 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. 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 18). 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 Normal Guide Bar Maintenance 1. Remove guide bar from chain saw. 2. Remove sawdust from guide bar groove periodically. Use putty knife or wire. 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, on back cover, for proper bar. Burr WARNING: When cleaning saw body, • do not submerge saw in any liquids • do not use products that contain ammonia, chlorine, or abrasives • do not use chlorinated cleaning solvents, carbon tetrachloride, kerosene, or gasoline Keep saw body clean. Use a soft cloth dampened with a mild soap and water mixture. Wipe saw body to clean.

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 20 and 21). 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 20). 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 20). 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. 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.
