WARNING: Read and understand all instructions. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury. READ ALL INSTRUCTIONS  Know your tool. Read the operator’s manual carefully. Learn the saw’s applications and limitations as well as the specific potential hazards related to this tool. ■ Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut. Tip contact in some cases may cause a lightning-fast reverse reaction, kicking the guide bar up and back toward the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back toward the operator. Either of these reactions may cause you to lose control of the saw, which could result in serious personal injury. Do not rely exclusively upon the safety devices built into the saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accident or injury. • With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents. • Keep a good firm grip on the saw with both hands when the engine is running. Place your right hand on the rear handle and your left hand on the front handle with your thumbs and fingers encircling the chain saw handles. A firm grip together with a stiff left arm will help you maintain control of the saw if kickback occurs. • Make 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 that could be hit while you are operating the saw. • Cut at high engine speeds. Always cut with the engine running at full speed. Fully squeeze the throttle trigger and maintain a steady cutting speed. • Do not overreach or cut above chest height. • Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. • Only use replacement bars and chains specified by the manufacturer or the equivalent.  Do not operate a chain saw with one hand. Serious injury to the operator, helpers, bystanders, or any combination of these persons may result from one-handed operation. A chain saw is intended for two-handed use.  Do not operate a chain saw when you are fatigued. Fatigue causes carelessness. Be more cautious before rest periods and towards the end of your shift. Never operate a chain saw when you are tired or under the influence of medication, drugs, or alcohol.  Use safety footwear. Wear snug-fitting clothing, ­protective gloves, and eye, hearing, and head protection devices.  Heavy protective clothing may increase operator fatigue, which could lead to heat stroke. During weather that is hot and humid, heavy work should be scheduled for early morning or late afternoon hours when temperatures are cooler.  Do not stand on any unstable surface while using the chain saw, that includes ladders, scaffolds, trees, etc.  Use caution when handling fuel. Move the chain saw at least 30 feet from the fueling point before starting the engine.  Do not allow other persons to be near the chain saw when starting or cutting with the chain saw. Keep bystanders and animals out of the work area.  Do not start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree.  Keep all parts of your body away from the saw chain when the engine is running.  Always carry the chain saw with the engine stopped and the chain brake engaged, the GENERAL SAFETY RULES

WARNING: The warnings, labels, and instructions found in this section of the operator’s manual are for your safety. Failure to follow all instructions may result in serious personal injury.  Do not cut vines and/or small underbrush (a diameter of less than 3 in.).  Muffler surfaces are very hot during and after operation of the chain saw; keep all body parts guide bar and saw chain to the rear, and the muffler away from your body. When transporting the chain saw, use the appropriate guide bar scabbard.  Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released. ■ Shut off the engine before setting the chain saw down. Do not leave the engine running unattended. As an additional safety precaution, apply the chain brake prior to setting down the saw. ■ Use extreme caution when cutting small-size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance. ■ When cutting a limb that is under tension, be alert for springback so that you will not be struck when the tension in the wood fibers is released. ■ Keep the handles dry, clean, and free of oil or fuel ­mixture.  Beware of carbon monoxide poisoning. Operate the chain saw only in well-ventilated areas. ■ Do not operate a chain saw in a tree unless you have been specifically trained to do so.  Do not cut from a ladder; this is extremely dangerous.  All chain saw service, other than the items listed in the instruction manual and all maintenance, should be performed by competent chain saw service personnel. (For example, if improper tools are used to remove the flywheel or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel could occur and subsequently could cause the flywheel to burst.)  Always have a fire extinguisher available when using chain saw.  Use only the replacement guide bars and low kickback chains specified for the saw. ■ Do not adapt the powerhead to a bow guide or use it to power any attachments or devices not listed for the saw. ■ The gas powered saw (or electrically powered saw) is classified by CSA as a Class 1C (or Class 2C) saw. It is intended for infrequent use by homeowners, ­cottagers, and campers, and for such general applications as clearing, pruning, cutting firewood, etc. It is not intended for prolonged use. Prolonged periods of operation can cause circulatory problems in the user’s hands due to vibration. For such use, it may be appropriate to use a saw having an anti-vibration feature.  Save these instructions. Refer to them frequently and use to instruct other users. If you loan someone this product, loan them these instructions also. away from the muffler. Serious burns may occur if contact is made with the muffler. ■ Always hold the chain saw with both hands when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles. ■ Never let anyone use the chain saw who has not received adequate instructions in its proper use. This applies to rentals as well as privately owned saws. GENERAL SAFETY RULES SPECIFIC SAFETY RULES

Refer to Adjusting the Carburetor in the Maintenance section of this manual. If the saw chain still moves at idle speed after adjustment has been made, contact an authorized service center for adjustment and discontinue use until the repair is made. REFUELING (DO NOT SMOKE!) ■ To reduce the risk of fire and burn injury, handle fuel with care. It is highly flammable. ■ Mix and store fuel in a container approved for gasoline. ■ Mix fuel outdoors where there are no sparks or flames. ■ Select bare ground, stop the engine, and allow it to cool before refueling. ■ Loosen the fuel cap slowly to release pres- sure and to keep fuel from escaping around the cap. ■ Tighten the fuel cap securely after refueling. ■ Wipe spilled fuel from the unit. Move 30 feet away from refueling site before starting engine.  Never attempt to burn off spilled fuel under any circumstances. KICKBACK  Kickback is a dangerous reaction that can lead to serious injury. Do not rely only on the safety devices provided with the saw. As a chain saw user, you must take special safety precautions to help keep your cutting jobs free from accident or injury. See the General Safety Rules and Operation sections of this manual for added information on kickback and how to avoid serious personal injury. ■ Before you start the engine, make sure the saw chain is not contacting any object.  Wear snug-fitting clothing. Always wear heavy, long pants, boots, and gloves. Do not wear jewelry, short pants, sandals, or go bare- foot. Do not wear loose fitting clothing, which could be drawn into the engine or catch the chain or underbrush. Wear overalls, jeans, or chaps made of cut-resistant material or ones that contain cut-resistant inserts. Secure hair so that it is above shoulder level. ■ Wear non-slip safety footwear and heavy- duty gloves to improve your grip and to protect your hands. ■ Wear eye protection with side shields which is marked to comply with ANSI Z87.1, as well as hearing and head protection, when operat- ing this equipment.  Keep bystanders and animals out of the work area. Do not allow other persons to be nearby during starting or cutting with the chain saw. NOTE: The size of the work area depends on the job being performed as well as the size tree or workpiece involved. For example, felling a tree requires a larger work area than making other cuts (i.e., bucking cuts, etc.).  Keep SAFE-T-TIP® anti-kickback nose guard properly mounted on the guide bar to prevent rotational kickback.  Follow the sharpening and maintenance instructions for the saw chain.  Never operate a chain saw that is damaged, improperly adjusted, or is not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released. If the saw chain moves at idle speed, the carburetor may need ­adjusting.
