User manual MCCULLOCH BC040

[. . . ] In the manual there will be the following call-outs: NOTE:, WARNING / CAUTION and WARRANTY. a NOTE: is used to convey additional information , to highlight a particular explanation , or to expand a description. A WARNING or CAUTION identifies a procedure which, if not undertaken or if improperly done, can result in serious personal injury and/or damage to the unit. The (WARRANTY SYMBOL) serves notice that unless instructions or procedures are followed, any damage caused will void the warranty and repairs will be at owner's expense. [. . . ] 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. 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. Running the saw DRY or with TOO LITTLE OIL will decrease cutting efficiency, shorten chain saw life, and cause rapid dulling of the chain and excessive wear of the bar from overheating. NOTE: The saw chain stretches during use, particularly when it is new, and occasional adjustment will be needed. A new chain requires more frequent adjustment during the break-in period. If the chain and motor fail to stop when the CHAIN BRAKE is engaged, take the saw to the nearest Authorized Service Center. Do not use the saw if the CHAIN BRAKE® is not in proper working order. When diameter of wood being cut is greater than the bar length, make 2 cuts as shown (Figure 5-1D). Small trees up to 6-7 inches (15-18cm) in diameter are usually cut in a single cut. Normal safety precautions must be observed when operating an electrical appliance. The double insulation system is only for added protection against injury resulting from a possible internal electrical insulation failure. For service information, contact the McCulloch Product Service Department toll-free number listed on the back cover of this manual. A retreat path (A) should be planned and cleared as necessary before cuts are started. The retreat path should extend back and diagonally to the rear of the expected line of fall, as illustrated in Figure 5-1A. 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. 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. [. . . ] Check the chain tension frequently and adjust as often as necessary to keep the chain snug on the bar, but loose enough to be pulled around by hand. A new chain and bar will need readjustment after as few as five (5) cuts. 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. [. . . ]
