Never operate a chain saw holding it with one hand only. [. . . ] Inexperienced users of chain saws should not fell trees. NEVER ATTEMPT A TASK YOU ARE UNSURE OF. A Start by cutting from below (about 1/3 of the way through). A Safe distance The safe distance between a tree that is to be felled and anyone else working nearby is at least 21/2 tree lengths. Make sure that no-one else is in this “risk zone” before or during felling. B Finish by cutting from above so that the two cuts meet. 3 The log is supported at both ends. There is a high risk that the chain will jam. B Felling direction The aim is to fell the tree in the best possible position for subsequent limbing and cross-cutting. You want it to fall on ground where you can move about safely. The main point to avoid is letting the tree fall onto another tree. It can be both difficult and dangerous to remove a tree in such a position (see point 4 in this section). Once you have decided which way you want the tree to fall you must judge which way the tree would fall naturally. Several factors affect this: Lean of the tree Bend A Start by cutting from above (about 1/3 of the way through). B Finish by cutting from below so that the two cuts meet. Limbing When limbing thick branches you should use the same approach as for cutting. Cut difficult branches piece by piece. 1 2 3 Wind direction Arrangement of branches Weight of snow You may find you are forced to let the tree fall in its natural direction because it is impossible or dangerous to try to make it fall in the direction you first intended. Another very important factor, which does not affect the felling direction but does affect your safety, is to make sure the tree has no damaged or dead branches that might break off and hit you during felling. During critical felling operations, hearing protectors should be lifted immediately when sawing is completed so that sounds and warning signals can be heard. English – 21 SAFETY INSTRUCTIONS C Clearing the trunk and preparing your retreat Remove any branches that are in the way. To do this it is best to work from the top down and keep the trunk between you and the chain saw. Never limb above shoulder height. FELLING CUT The felling cut is made from the opposite side of the tree and it must be perfectly horizontal. Stand on the left side of the tree and cut with the bottom edge of the bar. Make the FELLING CUT about 3-5 cm (1. 5-2 inches) above the flat section of the DIRECTIONAL CUT. Remove any undergrowth from the base of the tree and check the area for obstacles (stones, branches, holes, etc. ) so that you have a clear path of retreat when the tree starts to fall. Your path of retreat should be roughly 135 degrees behind the intended felling direction. Use full throttle and bring the bar and chain slowly into the tree. Make sure the tree does not start to move in the opposite direction to your intended felling direction. Drive a WEDGE or BREAKING BAR into the cut as soon as it is deep enough. Finish the FELLING CUT parallel with the DIRECTIONAL CUT LINE so that the distance between them is at least at least 1/10 of the trunk diameter. The uncut section of the trunk is called the BREAKING STRIP. D Felling Felling is done using three cuts. First you make the DIRECTIONAL CUTS, which consist of the TOP CUT and the BOTTOM CUT; followed by the FELLING CUT. [. . . ] We recommend that you as replacement use the listed chains or "Low kickback saw chains" which are available at your dealer.
