[. . . ] With proper operation and maintenance, it will provide you with years of service. In order to make the best use of your investment, be CERTAIN to familiarize yourself with the contents of the ENTIRE user manual before attempting to operate and maintain your unit. Be sure to carefully follow the step-by-step instructions in this manual to start, operate and maintain your new product. In the manual there will be the following call-outs: NOTE:, WARNING / CAUTION and WARRANTY. [. . . ] NOTE: The brake lever should snap into both positions. If strong resistance is felt, or lever does not move into either position, do not use your saw. Take it immediately to an Authorized Service Center for repair. If saw chain is TOO LOOSE or TOO TIGHT, the sprocket, bar, chain, and crankshaft bearings will wear more rapidly. Study Figure 3-4B for information concerning correct cold tension (A), correct warm tension (B), and as a guide for when saw chain needs adjustment (C). Always wear heavy duty gloves when handling saw chain or making saw chain adjustments. Hold nose of guide bar up and turn adjustment chain ring (A) CLOCKWISE to increase chain tension. Using a Phillips or slotted screwdriver - turn screw 1/4 to 1/2 turn clockwise (to the right). (Figure 5-2H) NOTE: If chain turns while idling - turn screw back to the left until chain stops and unit continues to idle. Some conventional gasolines are being blended with oxygenates such as alcohol or an ether compound to meet clean air standards. Your McCulloch engine is designed to operate on any gasoline intended for automotive use including oxygenated gasolines. The retreat path should extend back and diagonally to the rear of the expected line of fall, as illustrated in Figure 6-1A. As the felling cut gets close to the hinge, the tree should begin to fall. When tree begins to fall, remove saw from cut, stop engine, put chain saw down, and leave area along retreat path (Figure 6-1A). Release trigger and allow engine to return to idle speed. Press STOP switch down to stop engine Figure 5-4A. NOTE: For emergency stopping, simply activate CHAIN BRAKE® and move STOP switch down. If felling a tree on sloping ground, the chain saw operator should keep on the uphill side of the terrain, as the tree is likely to roll or slide downhill after it is felled. nOTE: Direction of fall (B) is controlled by the notching cut. Before any cuts are made, consider the location of larger branches and natural lean of the tree to determine the way the tree will fall. 5-5A Do not cut down a tree during high or changing winds or if there is a danger to property. Do not cut down a tree if there is a danger of striking utility wires; notify the utility company before making any cuts. [. . . ] Chain sharpening requires special tools to ensure that cutters are sharpened at the correct angle and depth. For the inexperienced chain saw user, we recommend that the saw chain be professionally sharpened by the nearest Authorized Service Center. If you feel comfortable sharpening your own saw chain, special tools are available from the nearest Authorized Service Center. Most guide bar problems can be prevented merely by keeping the chain saw well maintained. [. . . ]
