Do not relax your grip on chain saw handles. Do not let moving chain touch ground. Ground will dull moving chain. After cutting through log, release trigger to turn saw off before moving saw. Follow directions below to buck a log. LIMBING A TREE Figure 12 - Limbing A Tree WARNING: When cutting limb that is under tension, use extreme caution. Be alert for wood springing back. When wood tension is released, limb could spring back and strike operator causing severe injury or death. WARNING: Avoid kickback. Kickback can result in severe injury or death. See Kickback, page 3 to avoid risk of kickback. Limbing is removing branches from a fallen tree. Make sure your footing is firm. Keep feet apart. Divide your weight evenly on both feet. Do not remove larger limbs under tree that support log off ground. Remove each limb with one cut (see Figure 12). Clear cut limbs from work area often. This will help maintain a safe work area. Make sure you start your cut where limb will not pinch saw during cutting. To avoid pinching, start cut on freely hanging limbs from above limb. Start cut on limbs under tension from under limb. If pinch occurs, turn saw off, lift limb, and remove saw. Entire Length Of Log On Ground Cut log from top (see Figure 13). Figure 14 - Bucking Log When Log Is Supported On One End 1st Cut 2nd Cut OPERATING CHAIN SAW Continued Log Supported On One End 1. Make first cut on underside of log (see Figure 14). Use top of guide bar to make this cut. Cut 1/3 through diameter of log. This cut will keep section from splintering when cut. 2. Make second cut directly above first cut. Cut down to meet first cut. This cut will keep log from pinching guide bar and chain. OWNER’S MANUAL OPERATING CHAIN SAW Continued Log Supported On Both Ends 1. Make first cut from above log (see Figure 15). Cut 1/3 through diameter of log. This cut will keep section from splintering when cut. 2. Make second cut on underside of log, directly under first cut. Use top of guide bar to make this cut. Cut up to meet first cut. This will keep log from pinching guide bar and chain. 1st Cut 2nd Cut Figure 15 - Bucking Log When Log Is Supported On Both Ends TRIMMING A TREE (Pruning) WARNING: Avoid kickback. Kickback can result in severe injury or death. SeeKickback, 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 16). 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 16 - Cutting A Limb 11 For more information, visit ® ® 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 17). 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, page 19, for proper bar.
