SPECIFIC SAFETY RULES

nKickback is a dangerous reaction that can lead to serious injury. Kickback may occur when the moving chain con- tacts an object at the upper portion of the tip of the guide bar or when the wood closes in and pinches the chain in the cut. Contact at the upper portion of the tip of the guide bar can cause the chain to dig into the object and stop the chain for an instant. The result is a lightning-fast, reverse reaction which kicks the guide bar up and back toward the operator. If the chain is pinched along the top of the guide bar, the guide bar can be driven rapidly back toward the operator, which can cause loss of control and may result in serious injury. Do not rely exclusively upon the safety devices built into the product.

With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents.

nMake sure that the area in which you are cutting is free from obstructions. Do not let the nose of the guide bar contact a log, branch, fence, or any other obstruction while you are operating the unit.

nCut only when visibility and light are adequate for you to see clearly.

nDo not use on a ladder or unstable support. Always cut with both feet on solid ground to prevent being pulled off balance.

nTo protect yourself from electrocution, do not operate within 50 feet of overhead electrical lines.

nBefore starting the engine, make sure the chain is not contacting any object.

nAlways cut with the engine running at full speed. Fully squeeze the throttle trigger and maintain a steady cutting speed.

nDo not force tool. Use the correct tool for your applica- tion. The correct tool will do the job better and safer at the rate for which it is designed.

nTo protect yourself from falling branches, do not stand di- rectly under the branch or limb being cut. This unit should not be held at an angle over 60° from ground level.

nKeep the handles dry, clean, and free of oil or fuel mix- ture.

nShut off the engine and make sure the cutting attachment has stopped before setting the unit down.

nTo prevent electrical shock or serious personal injury, do not use this product with any AC power head.

nFollow the sharpening and maintenance instructions for the saw chain.

nUse only the replacement guide bars and low kickback chains specified for the unit.

REFUELING

nFUEL IS HIGHLY FLAMMABLE. Take precautions when using to reduce the chance of serious personal injury.

nStore fuel in a cool, well-ventilated area, safely away from spark and/or flame-producing equipment

nStore fuel in containers specifically designed for this purpose.

nOnly refuel outdoors and do not smoke while refueling.

nAdd fuel before starting the engine. Never remove the cap of the fuel tank or add fuel while the engine is running or when the engine is hot.

nIf fuel is spilled, do not attempt to start the engine but move the machine away from the area of spillage and avoid creating any source of ignition until fuel vapors have dissipated.

nReplace all fuel tank and container caps securely.

nIf the fuel tank has to be drained, do this outdoors.
