Page 2 GENERAL SAFETY RULES WARNING: Read and understand all instructions. Failure to follow all instructions listed below, may result in electric shock, fire and/or serious personal injury. protective gloves, and eye, hearing, and head protection devices. 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 brake engaged, the 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. 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, Page 3 GENERAL SAFETY RULES 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 tool, loan them these instructions also. SPECIFIC 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. 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. 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. 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 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. REFUELING (DO NOT SMOKE!)
