WARNINGS AND SAFETY INSTRUCTIONS (continued) OPERATE YOUR. SAW SAFELY 1. Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. 2. Operate the chain saw only in outdoor areas. 3. Do not operate saw from a ladder or in a tree. 4. Position all parts of yourbodytothe left of the cut and away from the saw rhain when the engine is running. 5. Cut wood only. Do not cut metal, plastics, masonry, non-wood buildingmaterials, etc. Do not use thesaw to pry or shove away limbs, roots, or other objects. 6. Make sure the chain will not make contact with any object while starting the engine. Never try to start the saw when guide bar is in a cut or kerf. 7. Use extreme caution when cutting small size brush and saplings. Slender material can catch the saw chain and be whipped toward you or pull you off balance. 8. Be alert for springback when cutting a limb that is under tension so you will not be struck by the limb or saw when tension in the wood fibers is released. 9. Do not put pressure on the saw at the end of a cut. Applying pressure can cause you to lose control when the cut is completed. 10. Stop the engine before setting the saw down. 11.Engage the chain brake when engine is running but not involved in a cutting procedure. MAINTAIN YOUR SAW IN GOOD WORKING ORDER 1. Have all chain saw service performed by a qu- alified service dealer with the exception of the items listed in the maintenance section of this manual. For example,ifimpropertools are used to remove or hold the flywheel when servicing the clutch, structural damage to the flywheel can occur and cause the flywheel to burst. 2. Keep fuel and oil caps, screws, and fasteners securely tightened. 3. Keep the handles dry, clean, and free of oil or fuel mixture. 4. Make certain the saw chain stops moving when the throttle trigger is released. For cor- rection, refer to the "Trouble Shooting Chart." 5. Stop the saw if chain strikes a foreign object. Inspect unit and repair or replace parts as necessary 6. Disconnect spark plugbefore performingany maintenance except for carburetor adjustments. 7. Never modify your saw in any way. Use only at- tachments supplied or specifically recommended by the manufacturer. 8. Always replace the chain brake immediately if it becomes damaged, broken, or is other wise removed. 9. Keep the vibration isolators in good condition. Periodically inspect isolators for tears, rips, or separation of the rubber portion from the metal mountings. Have a qualified service dealer replace the isolators if worn or damaged, if vibration increases, or if mounts develop an out of round or swol- len shape from exposure to gasoline and/or oil. CARRY AND STORE YOUR SAW SAFELY 1. Hand carryyour sawwith the engine stopped, the muffler away from your body, and the guide bar and chain to the rear covered preferably with a scabbard. 2. Before transporting in any vehicle or storing in any enclosure, allowyour sawto cool complete- ly, cover the bar and chain, and properly secure to avoid turnover, fuel spillage, or damage. 3. Empty the fuel tank before storing the tool. Use up the fuel left in the carburetor by starting the engine and letting the engine run until it stops. 4. Store unit and fuel in a dry area out of the reach of children. Do not store where fuel vapors can reach sparks or an open flame from hot water heaters, electric motors or switches, furnaces, etc. NOTICE: Refer to the Code of Federal Regulations, Section 1910.266(5); 2.5.1 of American National Standard Safety Requirements for Pulpwood Logging, ANSI 03.1-1978; and relevant state safety codes when using a chain saw for logging purposes. A WARNING The following features are available for your saw (in models equipped with 16",'20", and 24" 0.050 gauge bars) to help reduce the hazard of kickback; however such features will not totally eliminate this dangerous reaction. As a chain saw user, do not rely only on safety devices. You must follow all safety precautions, instructions, and maintenance in this manual to help avoid kickback and other forces which can result in serious injury. KICKBACK SAFETY FEATURES • Position of front and rear handlebars, designed with distance between handles and "in line" with each other. The spread and "in line" position of the hands provided by this design work together to give balance and resistance in controlling the pivot of the saw back toward the operator if kickback occurs. • Chain Brake, if activated during kickback, is a device to stop the chain. Do not rely on the chain brake to protect you against injury from kickback. Although it may appear the chain is stopping quickly, it still may not be fast enough to provide protection in the event of kickback. • Optional Reduced-Kickback Guide Bar, designed with a small radius tip which reduces the size of the kickback danger zone on the bar tip. Figure 5 . A reduced-kickback guide bar has been demonstrated to reduce the hazard of kickback. • Optional Low-Kickback Chain, designed with a contoured depth gauge and elongated guard link which allows wood to gradually ride into the cutter. Figure 5. Low-Kickback Chain has been demonstrated to reduce kickback significantly. •Small Reduced lakback Radius Tip Symmetrical Guide Bar Contoured de, Depth Gauge Elongated Guard Link Low-Kickback Chain ( Deflects lOckback Force And Allows Wood To Gradually Ride Into Cutter Symmetrical Guide Bar R Large Radius Tip Chain With High Kickback Potential Figure 5 Can Obstruct Material
