[. . . ] 3-4C Using a funnel, fill oil tank with Genuine Factory Parts Chain, Bar and Sprocket oil. Make sure no dirt gets into the oil tank. The saw chain requires lubrication while in use to minimize friction with the guide bar. 5 ozs of oil, enough to lubricate the chain for 12-15 minutes of sawing. We recommend using Genuine Factory Parts Chain, Bar and Sprocket Oil, which contains additives to reduce friction wear and reduce resin residue formations. The oil tank level should be frequently checked during operation to avoid starving the bar and chain of lubrication. NOTE: Your chain saw is equipped with an Automatic Oiler system and is the ONLY source of lubrication for the bar and chain (Figure 3-5A). Adequate lubrication of the saw chain during cutting operations is essential to minimize friction with the guide bar. Your chain saw is equipped with an automatic oiler system. The oiler automatically delivers the proper amount of oil to the bar and chain. The oil tank level can be checked in the inspection slot (A) provided on the right side of the saw. This McCulloch chain saw is equipped with chain brake/hand guard. The Hand Guard protects your left hand in the event it slips off the front handle. The CHAIN BRAKE® is a safety feature which is activated if pressure is applied against the guard or when, in the event of kickback, the operator's hand strikes the lever. When the CHAIN BRAKE® is activated, chain movement abruptly stops and the power supply to the motor is immediately cut off. the purpose of the CHAIN BRAKE® is to reduce the possibility of injury due to kickback. The CHAIN BRAKE® cannot, however, provide the measure of intended protection if the saw is carelessly operated. Before cutting with your saw, the CHAIN BRAKE® should be tested as follows: A. Place the saw on a firm, flat, dry surface that is clear of any debris. Do not let the saw come in contact with any objects. Grasp the front handle (not the CHAIN BRAKE®/Hand Guard Lever) with your left hand. While the motor is running, activate the CHAIN BRAKE® by rolling your left hand forward against the lever. [. . . ] This is normal during the break-in period, and the interval between future adjustments will begin to lengthen quickly. Over a period of time, however, the moving parts of the saw chain will become worn, resulting in what is called CHAIN STRETCH. When it is no longer possible to obtain correct chain tension adjustment, a link will have to be removed to shorten the chain. See your nearest Authorized Service Center to have this repair performed. [. . . ]
