5 SAFETY Precautions Against Kickback Kickback is a dangerous reaction that can lead to serious injury. Do not rely only on the safety devices provided with your saw. As a chain saw user, you must take special safety precautions to help keep your cutting jobs free from accident or injury. SÉCURITÉ Précautions pour éviter le rebond du guide-cha?[...]

6 SAFETY • With a basic understanding of kick- back, 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 run- ning. Place your right hand on the rear handle and the left hand on the front handle with your thumbs and fingers encirclin[...]

7 • 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 operate a chain saw when you are fatigued. • 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 chai[...]

8 SAFETY • Never let anyone use your chain saw who has not received adequate in- structions in its proper use. This applies to rentals as well as privately owned saws. Keep the handles dry, clean, and free of oil or fuel mixture. • Before you start the engine, make sure the saw chain is not contacting any object. • Shut off the engine before [...]

9 A B SAFETY Kickback ROTATIONAL KICKBACK ( A ) occurs when the moving chain contacts an object at the Kickback Danger Zone ( B ) of the guide bar zone. The result is a lightning fast, reverse reaction which kicks the guide bar up and back towards the operator. This reaction can cause loss of control which can result in seri- ous injury. SÉCURITÉ[...]

10 SEGURIDAD • Limpie el combustible derramado existente en la unidad. Desplácese 30 pies (10 m) del punto donde haya echado el combustible antes de poner en marcha el motor. • No intente nunca quemar el combustible derramado bajo ninguna circunstancia. Mantenimiento • No opere nunca una motosierra que esté dañada, ajustada de forma inadec[...]

11 A SAFETY • Never start cutting until you have a clear work area, secure footing, and a planned retreat path from the falling tree. • Use extreme caution when cutting small size brush and saplings, be- cause slender material may catch the saw chain and be whipped toward you or pull you off balance. • When cutting a limb that is under tensio[...]

12 SAFETY Low Kickback Saw Chain The rakers (depth gauges) ahead of each cutter can minimize the force of a kick- back reaction by preventing the cutters from digging in too deeply at the kick- back zone. Only use replacement chain that is equivalent to original chain or has been certified as low kickback chain per ANSI B175.1. Low kickback saw cha[...]

13 SAFETY Chain Brake Chain brakes are designed to rapidly stop the chain from rotating. When the chain brake lever / hand guard is pushed toward the bar, the chain should stop immedi- ately. A chain brake does not prevent kickback. A ) RUN POSITION B ) BRAKE POSITION Chain brake should be cleaned and tested daily. Clean the chain brake per the Mai[...]

22 OPERATION Proper Cutting Stance • Weight should be balanced with both feet on solid ground. • Keep left arm with elbow locked in a "straight arm" position ( D ) to with- stand any kickback force. See Illus- tration ( E ). • Your body should always be to the left of the chain line ( F ). • Thumb on underside of handlebar ( G ). [...]

23 • Always cut with both feet on solid ground to prevent being pulled off balance. • Do not cut above chest height, as a saw held higher is difficult to control against kickback forces. • Do not fell trees near electrical wires or buildings. Leave this operation for professionals. • Cut only when visibility and light are adequate for you t[...]

24 STOP OPERATION Carburetor Adjustment Before adjusting the carburetor, clean the air filter ( A ), see Maintenance-Air Filter Section. Also clean the starter cover vents as shown in Illustration ( B ). Allow the engine to warm up prior to carburetor adjustment. This engine is designed and manufac- tured in order to comply with EPA (Envi- ronmenta[...]

25 STOP W ARNING Weather conditions and altitude may affect carburetion. Do not allow bystanders close to the chain saw while adjusting the carbu- retor.

28 B B OPERATION 1. Pick your escape route (or routes in case the intended route is blocked). Clear the immediate area around the tree, and make sure there are no obstructions in your planned path of retreat. Clear path of safe retreat ( A ) approximately 135° from planned line of fall ( B ). 2. Consider the force and direction of the wind, the le[...]

29 C E F G OPERATION 5. Never cut through to the notch. Al- ways leave a band of wood between the notch and back cut (approxi- mately 2 inches (5 cm) or 1/10 the diameter of the tree). This is called "hinge" ( E ) or “hingewood.” It con- trols the fall of the tree and prevents slipping or twisting or shoot-back of the tree off the stu[...]

30 Bucking Bucking is the term used for cutting a fallen tree to the desired log length. • Cut only one log at a time. • Support small logs on a saw horse or another log while bucking. • Keep a clear cutting area. Make sure that no objects can contact the guide bar nose and chain during cutting, this can cause kickback ( D ). To avoid the dan[...]

31 OPERATION • During bucking operations always stand on the uphill side so that the cut-off section of the log can not roll over you. • Sometimes it is impossible to avoid pinching (with just standard cutting techniques) or difficult to predict which way a log will settle when cut. To avoid pinching while cutting, re- view the following sectio[...]

32 Give special attention to logs under stress to prevent the bar and chain from pinching. Types of Cutting Used Overbucking Begin on the top side of the log with the bottom of the saw against the log; exert light pressure downward. Note that the saw will tend to pull away from you. Underbucking Begin on the under side of the log with the top of th[...]

33 A W ARNING Never climb into a tree to limb or prune. Do not stand on ladders, platforms, a log or in any position which can cause you to lose your balance or control of the saw. OPERATION Limbing and Pruning • Work slowly, keeping both hands on the saw with a firm grip. Maintain secure footing and balance. • Keep the tree between you and the[...]

34 OPERATION • When pruning trees it is important not to make the flush cut next to the main limb or trunk until you have cut off the limb further out to reduce the weight. This prevents stripping the bark from the main member. Underbuck the branch 1/3 through for your first cut ( A ), your second cut ( B ) should overbuck to drop the branch off.[...]

35 D OPERATION Springpoles A springpole ( D ) is any log, branch, rooted stump, or sapling which is bent under tension by other wood so that it springs back if the wood holding it is cut or removed. On a fallen tree, a rooted stump has a high potential of springing back to the upright position during the bucking cut to separate the log from the stu[...]
