Kickback may also occur when wood pinches chain at guide bar nose. A sudden reverse action will also result. The following steps will reduce the risk of kickback: • Use both hands to grip saw while saw is running. Use firm grip. Thumbs and fingers must wrap around saw handles. • Keep all safety items in place on saw. Make sure they work properly. • Do not overreach or cut above shoulder height. • Keep solid footing and balance. • Stand slightly to left side of saw. This keeps your body from being in direct line with chain. • Do not let guide bar nose touch anything when chain is moving (see Figure 1). • Never try cutting through two logs at same time. Only cut one log at a time. • Do not bury guide bar nose or try plunge cut (boring into wood using guide bar nose). • Watch for shifting of wood or other forces that may pinch chain. • Use extreme caution when re-entering a previous cut. • Use low-kickback chain and guide bar supplied with this chain saw. Only replace these parts with chains and guide bars listed in this manual. • Never use dull or loose chain. Keep chain sharp and tensioned correctly.

Do Not Let Nose of Guide Bar Touch Object While Chain is Moving Continued 100583 3 ®® ELECTRIC CHAIN SAW SAFETY WARNINGS Continued Saw Maintenance and Kickback Safety Follow maintenance instructions in this manual. Proper cleaning of saw and chain and guide bar maintenance can reduce chances of kickback. Inspect and maintain saw after each use. This will increase the service life of your saw. Note: Even with proper sharpening, risk of kickback can increase with each sharpening. PUSHBACK AND PULL-IN WARNING: Avoid pushback and pull-in. These hazards can cause you to lose control of chain saw. Pushback or pull-in can cause severe injury. Cause Of Pushback and Pull-In Pushback may occur while cutting with top of guide bar. Pushback will force saw back towards you. Pull-in may occur while cutting with bottom of guide bar. Pull-in will force saw in towards wood you are cutting. These hazards can occur if chain is pinched, caught, or contacts a non-wood object. The following steps will reduce the risk of pushback or pull-in: • Use both hands to grip saw while saw is running. Use firm grip. Thumbs and fingers must wrap around saw handles. • Do not overreach or cut above shoulder height. • Keep solid footing and balance. • Stand slightly to left side of saw. This keeps your body from being in direct line with chain. • Have saw running at full speed before starting a cut. • When cutting, make sure spike of saw is against wood (pull-in only). See Product Identification, page 6, to locate spike. • Never try cutting through two logs at same time. Only cut one log at a time. • Watch for shifting of log or other forces that may pinch chain. • Use extreme caution when re-entering a previous cut. • Do not twist saw when removing guide bar from undercut. • Use wedges made of plastic, wood, or light alloy (never steel or iron) to hold cut open. CHAIN SAW OPERATION 1. Stay alert. Use common sense while operating chain saw. 2. Keep work area clean. Cluttered areas invite injuries. 3. Be aware of extension cord while operating chain saw. Be careful not to trip over cord. 4. Keep children, animals, and bystanders away from chain saw and extension cord. Only chain saw user should be in work area. 5. Do not cut down a tree unless you are trained or have expert help. 6. If two or more persons perform bucking and felling operations at the same time, provide plenty of distance between operations. Provide distance of at least twice the height of tree being felled. 7. Secure wood you are cutting by using clamps or chocks. 8. Grip chain saw firmly with both hands. Never operate chain saw with one hand. Never use hand guard as handle. 9. Keep finger off trigger until ready to make cut. 10. Before starting chain saw, make sure chain is not touching anything. 11. Avoid body contact with grounded object...
