English Chain catcher The chain catcher is located on the power head just below the chain to further prevent the possibility of a broken chain striking the chain saw user. WARNING Do not stand in-line with chain when cutting. Basic techniques for making felling, limbing and bucking cuts The intention of the following information is to provide you with the general introduction to wood cutting techniques. WARNING ○ This information does not cover all specific situations, which may depend on differences in terrain, vegetation, kind of wood, form and size of trees, etc. Consult your servicing dealer, forestry agent or local forestry schools for advice on specific woodcutting problems in your area. This will make your work more efficient and safer. ○ Avoid cutting in adverse weather conditions, such as dense fog, heavy rain, bitter cold, high winds, etc. Adverse weather is often tiring to work in and creates potentially dangerous conditions such as slippery ground. High winds may force the tree to fall in an unexpected direction causing property damage or personal injury. CAUTION Never use a chain saw to pry or for any purpose for which it is not intended. WARNING ○ Avoid stumbling on obstacles such as stumps, roots, rocks, branches and fallen trees. Watch out for holes and ditches. Be extremely cautious when working on slopes or uneven ground. Shut off the saw when moving from one work place to another. Always cut at wide open throttle. A slow moving chain can easily catch and force the saw to jerk. ○ Never use the saw with only one hand. You cannot control the saw properly and you may lose control and injure yourself severely. Keep the saw body close to your body to improve control and reduce strain. When cutting with the bottom part of the chain the reactive force will pull the saw away from you towards the wood you are cutting. The saw will control the feeding speed and sawdust will be directed towards you. (Fig. 22) 12 Fig. 22 ○ When cutting with the upper part of the chain the reactive force will push the saw towards you and away from the wood you are cutting. (Fig. 23) Fig. 23 ○ There is a risk of kickback if the saw is pushed far enough so that you begin to cut with the nose of the guide bar. The safest cutting method is to cut with the bottom part of the chain. Sawing with the upper part makes it much more difficult to control the saw and increases the risk of kickback. ○ In case the chain locked, immediately release the throttle trigger. If the throttle trigger keeps rotating at high speed with the chain locked, the clutch will overheat causing trouble. NOTE Always keep the spiked bumper face to a tree, because the chain may suddenly be drawn into a tree, if so equipped. Felling Felling is more than cutting down a tree. You must also bring it down as near to an intended place as possible without damaging the tree or anything else. Before felling a tree, carefully consider all conditions which may effect the intended direction, such as: Angle of the tree. Shape of the crown. Snow load on the crown. Wind conditions. Obstacles within tree range (e.g., other trees, power lines, roads, buildings, etc.). WARNING ○ Always observe the general conditions of the tree. Look for decay and rot in the trunk which will make it more likely to snap and start to fall before you expect it.
