Both must be read and understood for proper and safe operation. X7503203103 X750003242 06/05 RULES FOR SAFE OPERATION A. 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. [. . . ] The remaining wood between the notch cut and felling cut (about 2") will act as a hinge when the tree falls, guiding it in the desired direction. When the tree starts to fall, kill the engine, place the saw on the ground and make your retreat quickly. To fell big trees with a diameter exceeding twice the bar length, start the notching cuts from one side and draw the saw through to the other side of the notch. Start the back cut on one side of the tree, pivoting the saw through to form the desired hinge on that side. Insert the saw in the first cut, very carefully so as not to cause kickback. The final cut is made by drawing the saw forward in the cut to reach the hinge. LIMBING Limbing a fallen tree is much the same as bucking. Always use both hands. 13 Don't cut with the saw overhead or the bar in a vertical position. If the saw should kick back you may not have good enough control to prevent possible injury. BUCKING Bucking is the sawing of a log or fallen tree into smaller pieces. When cutting on a slope or hillside, always stand uphill. Uphill position FINISH CUT Keep in mind that the wood is heavy and that it will bend and pinch the saw if improperly supported. The trunk will weaken at the point where you make the cut unless the tree is lying on perfectly flat ground or supported as shown. If you make the cut with the tree on the ground, don't let the saw's chain dig into the earth; it is harmful for the saw, and you stand a good chance of being struck by flying debris. The first cut should be no deeper than one-third the trunk diameter. FIRST CUT Board or flat stones KICKBACK WARNING DANGER · Improper thrust cutting. KICKBACK IS DANGEROUS Kickback is generated when the rotation of the chain is arrested for some reason. The most dangerous effect of this action occurs when the nose of the bar contacts another object, the chain is momentarily stopped and all the energy of the engine throws the bar upwards and backwards towards the operator. The chain saw industry and government agencies have attempted to prescribe various safety devices, but the best protection is to avoid kickback.
