Important Safety Precautions for Chain Saw Users A. Kickback Safety Precautions !Warning! 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 towards the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back towards the operator.

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. Have your STIHL dealer show you how to operate your chainsaw.
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 By vehicle: The chain guard must be fitted on the guide bar when transporting the saw in a vehicle. The saw should be secured so that it cannot move and become damaged, or cause damage. 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.
english / USA !Warning! !Warning! !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).
english / USA If you use an extension cord, be sure to use one heavy enough to carry the current your electric saw will draw. An improper gauged extension cord will cause a drop in wire voltage resulting in loss of power and overheating. Use only extension cords having an electrical rating not less than the rating of the product. The following table shows the correct size to use depending on cord length and machine label ampere rating.
english / USA !Warning! Breathing asbestos dust is dangerous and can cause severe or fatal injury, respiratory illness or cancer. The use and disposal of asbestos containing products have been strictly regulated by OSHA and the Environmental Protection Agency. Do not cut or disturb asbestos, asbestos containing products (e.g. asbestos containing drywall or other construction products), or products such as pipes which are wrapped or covered with asbestos insulation.
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, the reactive 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 ANSI B 175.1-2000 chainsaw kickback standard Section 5.12 of ANSI standard B 175.1-2000, sets certain performance and design criteria related to chainsaw kickback, which has been adopted for electric chain saws in UL 16 62 in section 30.
english / USA On this electric chainsaw model, as soon as you release the trigger switch completely, the coasting chain brake is engaged and stops the chain. See the chapter entitled "Chain Brake" in your Owner's Manual. 001BA075 LÄ !Warning! When a kickback occurs, the guide bar may rotate around the front handle.
english / USA Please ask your STIHL dealer to properly match your powerhead with the appropriate bar/chain combinations to reduce the risk of kickback injury. Green labeled bars and chains are recommended for all powerheads. See your "STIHL Bar and Chain Information" leaflet for details. !Warning! Use of other, non-listed bar/chain combinations may increase kickback forces and increase the risk of kickback injury.
english / USA To avoid kickback 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. Do not cut limbs with the nose of the guide bar. Be especially careful when cutting small, tough limbs, small size brush and saplings which may easily catch the chain. 4 Don't overreach. 5. Don't cut above shoulder height. 6. Begin cutting and continue at full throttle. 7.
!Warning! !Warning! Working with an electric chain saw in the woods - i.e. felling or limbing - is very dangerous. The freedom of movement necessary for this work is impaired by the power cable! Electric saws are intended for stationary use in yards, buildings, etc. Always observe the general condition of the tree. Inexperienced users should never attempt to cut trees which are decayed or rotted inside or which are leaning or otherwise under tension.

If the tree has large buttress roots, cut into the largest buttress vertically first (horizontally next) and remove the resulting piece. A = felling notch - determines the direction of the fall Then, establish two paths of escape (B) and remove all obstacles.

In order to reduce the risk of personal injury, never stand directly behind the tree when it is about to fall, since part of the trunk may split and come back towards the operator (barber-chairing), or the tree may jump backwards off the stump. Always keep to the side of the falling tree.
english / USA If you are inexperienced with a chainsaw, plunge-cutting should not be attempted. Seek the help of a professional. 001BA089 LÄ 3 First, cut a large, wide felling notch. Make a plunge cut in the center of the notch. 2 001BA048 KN 1 Avoid repositioning the saw more than necessary. When repositioning for the next cut, keep the guide bar fully engaged in the kerf to keep the felling cut straight. If the saw begins to pinch, insert a wedge to open the cut.
Bucking 2. Cut only one log at a time. Bucking is cutting a log into sections. 3. Shattered wood should be cut very carefully. Sharp slivers of wood may be caught and flung in the direction of the operator of the saw. 4. When cutting small logs, place log through "V" - shaped supports on top of a sawhorse. Never permit another person to hold the log. Never hold the log with your leg or foot. !Warning! 1. When bucking, do not stand on the log. Make sure the log will not roll downhill.

Warranty claims following repairs can be accepted only if the repair has been performed by an authorized STIHL servicing dealer using original STlHL spare parts. This will make re-ordering simpler.
5. 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. Before you switch on the motor, make sure that the saw chain is not contacting anything. 8. Carry the chainsaw with the motor stopped, the guide bar and saw chain to the rear. 9. Do not operate a chainsaw that is damaged, improperly adjusted, or not completely and securely assembled. 10.
