[. . . ] Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc. Take great care when removing small branches and avoid cutting bushes (i. e. cutting many small branches at the same time). Small branches can be grabbed by the chain and thrown back at you, causing serious injury. • Never put a chain saw down while the engine is running unless you have it in clear view and the chain brake is on. Switch the engine off before leaving your chain saw for any length of time. • Basic cutting technique General • • • Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc. ) in case you have to move suddenly. Take great care when working on sloping ground. Reduce the speed to idle after every cut (running the engine for too long at full throttle without any load, i. e. without any resistance from the chain during cutting, can lead to serious engine damage). • Cutting from above = Cutting on the pull stroke. • Cutting from below = Cutting on the push stroke. Cutting on the push stroke increases the risk of kickback. See instructions under the heading How to avoid kickback. Terms Cutting = General term for cutting through wood. Limbing = Cutting branches off a felled tree. Splitting = When the object you are cutting breaks off before the cut is complete. 18 – English SAFETY INSTRUCTIONS There are five important factors you should consider before making a cut: 1 Make sure the cutting equipment will not jam in the cut. Cut all the way through the log from above. Avoid letting the chain touch the ground as you finish the cut. Maintain full throttle but be prepared for what might happen. 2 Make sure the object you are cutting will not split. If it is possible (can you turn the log?) stop cutting about 2/3 of the way through the log. 3 Make sure the chain will not strike the ground or any other object during or after cutting. Turn the log and finish the cut from the opposite side. 4 Is there a risk of kickback? The log is supported at one end. There is a high risk that it will split. 5 Do the conditions and surrounding terrain affect how safely you can stand and move about? Two factors decide whether the chain will jam or the object that you are cutting will split: the first is how the object is supported before and after cutting, and the second is whether it is in tension. In most cases you can avoid these problems by cutting in two stages; from the top and from the bottom. [. . . ] A hard nose bar having the same length and nose radius as a sprocket-nose bar may be considered to have equivalent or less kickback energy than the sprocket-nose bar. Low kickback saw chain is a chain which has only met the kickback performance requirements of ANSI B 175. 1 safety requirements for gasoline powered chain saws when tested on the representative sample of chain saws below 3. 8 cu. We recommend that you as a replacement use the listed chains or "Low kickback saw chains" which are available at your dealer.
