English / USA Some Important Safety Precautions for Chain Saw Users A. A Summary of Warnings on kickback and other Selected Risks – Taken Primarily from ANSI B 175.1 (See also “Safety Precautions“ section of this Owner’s Manual) Do not rely exclusively upon the safety devices built into your saw. As a chainsaw user, you should take several steps to keep your cutting jobs free from accident or injury. 1.
English / USA 4. Use caution when handling fuel. Move the chainsaw at least 10 feet (3 m) from the fueling point before starting the engine. 5. Do not allow other persons to be near the chainsaw when starting or cutting with the chainsaw. Keep bystanders and animals out of the work area. 6. 7. 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. 8.
English / USA Safety Precautions The use of any chainsaw may be hazardous. The saw chain has many sharp cutters. If the cutters contact your flesh, they will cut you, even if the chain is not moving. At full throttle, the chain speed can reach 45 mph (20 m/s). It is important that you read, fully understand and observe the following safety precautions and warnings. Read the Owner's Manual and the Safety Precautions periodically. Pay special attention to the section on reactive forces.
English / USA These conditions reduce the hand's ability to feel and regulate temperature, produce numbness and burning sensations and may cause nerve and circulation damage and tissue necrosis.
English / USA THE SAW Parts of the chainsaw; for illustrations and definitions of the parts see the chapter on "Main Parts of Saw". !Warning! Never modify a chainsaw in any way. Only attachments and parts supplied by STIHL or expressly approved by STIHL for use with the specific STIHL saw models are authorized. Although certain unauthorized attachments are usable with the STIHL powerhead, their use may, in fact, be extremely dangerous.
English / USA !Warning! Proper tension of the chain is extremely important. In order to avoid improper setting, the tensioning procedure must be followed as described in your manual. Always make sure the hexagonal nut(s) for the sprocket cover is (are) tightened securely after tensioning the chain. Never start the saw with the sprocket cover loose. Check chain tension once more after having tightened the nut(s) and thereafter at regular intervals (whenever the saw is shut off).
001BA113 KN Fold the grip flush with the top of the cap. If the grip does not lie completely flush with the cap and the detent on the grip does not fit in the corresponding recess in the filler neck, the cap is not properly seated and tightened and you must repeat the above steps. Starting Slotted Cap !Warning! Unit vibrations can cause an improperly tightened fuel filler cap to loosen or come off and spill quantities of fuel.
English / USA !Warning! Be sure that the guide bar and chain are clear of you and all other obstructions and objects, including the ground. When the engine is started, the engine speed with the starting throttle lock engaged will be fast enough for the clutch to engage the sprocket and, if the chain brake is not activated, turn the chain. If the upper quadrant of the tip of the bar touches any object, it may cause kickback to occur (see section on reactive forces).
English / USA !Warning! !Warning! To reduce the risk of fire or burn injury, keep the area around the muffler clean. Remove all debris such as pine needles, branches or leaves. Your chainsaw produces poisonous exhaust fumes as soon as the combustible engine is running. These gases (e.g. carbon monoxide) may be colorless and odorless. To reduce the risk of serious or fatal injury from breathing toxic fumes, never run the chainsaw indoors or in poorly ventilated locations.
English / USA Your chainsaw is equipped with a chain catcher. It is designed to reduce the risk of personal injury in the event of a thrown or broken chain. From time to time the catcher may be damaged or removed. To reduce the risk of personal injury, do not operate a chainsaw with a damaged or missing catcher. Inspect buffers periodically. Replace damaged, broken or excessively worn buffers immediately, since they may result in loss of control of the saw.
001BA082 KN 001BA018 LA English / USA Position the chainsaw in such a way that your body is clear of the cutting attachment whenever the engine is running. Stand to the left of cut while bucking. !Warning! 001BA031 KN Never touch a chain with your hand or any part of your body when the engine is running, even when the chain is not rotating. The chain continues to rotate for a short period after the throttle trigger is released. !Warning! Do not cut any material other than wood or wooden objects.
English / USA the powerful force used to cut wood can be reversed (and work against the operator). If the rotating chain is suddenly stopped by contact with any solid object like a log or branch or is pinched, there active forces may occur instantly. These reactive forces may result in loss of control which may, in turn, cause serious or fatal injury. An understanding of the causes of these reactive forces may help you avoid loss of control.
English / USA a) saws with a displacement of less than 3.8 cubic inches (62 cm³). – must, in their original condition, meet a 45° computer derived kickback angle when equipped with certain cutting attachments. – and must be equipped with at least two devices to reduce the risk of kickback injury, such as a chain brake, low kickback chain, reduced kickback bar, etc. b) saws with a displacement of 3.
English / USA !Warning! !Warning! Never operate your chainsaw without a front hand guard. In a kickback situation this guard helps protect your left hand or other parts of your body. In addition, removal of the hand guard on a saw equipped with a chain brake will deactivate the chain brake. An improperly maintained chain brake may increase the time needed to stop the chain after activation, or may not activate at all.
English / USA reduce the risk of kickback injury. Other chains are designed to obtain higher cutting efficiency or sharpening ease but may result in higher kickback tendency. STIHL has developed a color codesystem to help you identify the STIHL reduced kickback bars and low kickback chains. Cutting attachments with green warning decals or green labels on the packaging are designed to reduce the risk of kickback injury. The matching of green decaled powerheads under 3.
English / USA Reduced kickback bar STIHL green labeled reduced kickback bars are designed to reduce the risk of kickback injury when used with STIHL green labeled low kickback chains. To avoid kickback The best protection from personal injury that may result from kickback is to avoid kickback situations: 1. Hold the chainsaw firmly with both hands and maintain a secure grip. 2. Be aware of the location of the guide bar nose at all times. 3. Never let the nose of the guide bar contact any object.
English / USA Cutting Techniques Felling B = Pushback: Pushback occurs when the chain on the top of the bar is suddenly stopped when it is pinched, caught or encounters a foreign object in the wood. The reaction of the chain drives the saw straight back toward the operator and may cause loss of saw control. Pushback frequently occurs when the top of the bar is used for cutting. To avoid pushback 1. Be alert to forces or situations that may cause material to pinch the top of the chain. 2.
B English / USA 45° A 001BA019 KN 001BA041 KN B 001BA040 KN 45° Escape path Buttress roots Gunning sight First clear the tree base and work area from interfering limbs and brush and clean its lower portion with an ax. If the tree has large buttress roots, cut into the largest buttress vertically first (horizontally next) and remove the resulting piece.

This is the hinge Do not cut through the hinge - you could lose control of the direction of the fall Drive wedges into the felling cut where necessary to control the fall. !Warning! If the tip of the bar contacts a wedge, it may cause kickback.
English / USA 001BA089 LÄ 3 1 2 3 First, cut a large, wide felling notch. Make a plunge cut in the centre of the notch. 2 001BA047 KN 001BA048 KN 1 Felling cut for large diameter trees: !Warning! Felling a tree that has a diameter greater than the length of the guide bar requires use of either the sectioning felling cut or plunge-cut method. These methods are extremely dangerous because they involve the use of the nose of the guide bar and can result in kickback.
English / USA If you are inexperienced with a chainsaw, plunge-cutting should not be attempted. Seek the help of a professional. Limbing Limbing is removing the branches from a fallen tree. 001BA033 KN There is an extreme danger of kickback during the limbing operation. Do not work with the nose of the bar. Be extremely cautious and avoid contacting the log or other limbs with the nose of the guide bar. Do not stand on a log while limbing it you may slip or the log may roll.
English / USA MAINTENANCE, REPAIR AND STORING 001BA050 LÄ Maintenance, replacement, or repair of the emission control devices and systems may be performed by any nonroad engine repair establishment or individual. However if you claim warranty for a component which has not been serviced or maintained properly or if nonapproved replacement parts were used, STIHL may deny warranty. 5. 6. 7. 24 Logs under strain: Risk of pinching! Always start relieving cut (1) at compression side (A).
English / USA result. If your muffler was equipped with a spark-arresting screen to reduce the risk of fire (e. g. in the USA, Canada and Australia), never operate your saw if the screen is missing or damaged. Remember that the risk of forest fires is greater in hot or dry weather. Keep the chain, bar and sprocket clean; replace worn sprockets or chains. Keep the chain sharp. You can spot a dull chain when easy-tocut wood becomes hard to cut and burn marks appear on the wood.
