[. . . ] 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. Either of these reactions may cause you to lose control of the saw which could result in serious personal injury. [. . . ] The position of this notch is important since the tree will try to fall "into" the notch. The felling cut is made on the side opposite the notch and at a level about 2" above the bottom of the notch. Do not try to cut through to the notch with the felling cut. 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. Never limb on the tree that you are standing. Be careful of the tip touching other limbs. Always use both hands. 13 Don't cut with the saw overhead or the bar in a vertical position. Pull choke (A) all the way out (close position). Loosen bolt and remove air cleaner (B) cover and filter (C). Lightly brush dust off filter, and inspect for damage. AUTOMATIC OILER B D · The discharge volume of the automatic oiler is adjusted to 3 to 4 cc/mm (@ 7000 rpm) prior to shipment from the factory. · Always check oil discharge when in use. · Turn adjusting screw (D) counter-clockwise to increase oil volume, clockwise to decrease oil volume. OIL STRAINER · Check periodically. - Do not allow dust to enter into oil tank. - Clogged oil strainer will affect the normal lubricating system. - If the strainer (E) is dirty, wash it in gasoline. - When the inside of the tank gets dirty, rinsing the tank out with gasoline will clean it. - Clogged strainer will cause difficulty in starting engine or abnormalities in engine performance. - Pick up the fuel strainer (F) through fuel inlet port with a piece of steel wire, or the like. [. . . ] · Pour a small amount of clean two-stroke oil into spark plug hole, pull starter and crank engine until the piston is at TOP DEAD CENTER. · Store in a dry area, free from dust. 22 CORRECT USE OF CHAIN BRAKE The installation of a chain brake may be mandatory by law or as stipulated by insurance regulations in your area of operation. You should inquire through local government offices, your employer or your local dealer to ensure that your chain saw conforms to the required safety standard. [. . . ]
