GENERAL SAFETY PRECAUTIONS • Number of drive links. The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket. • A sharp chain eats its way through the wood and produces long, thick chips or shavings. • Bar groove width (inches/mm). The groove in the bar must match the width of the chain drive links. • The cutting part of the chain is called the cutter and consists of a cutting tooth (A) and the depth gauge (B). The cutters cutting depth is determined by the difference in height between the two (depth gauge setting). • Chain oil hole and hole for chain tensioner. The bar must be matched to the chain saw design. When you sharpen a cutting tooth there are four important factors to remember. 1 Filing angle Chain • Chain pitch (inches) 2 Cutting angle • Drive link width (mm/inches) 3 File position • Number of drive links. 4 Round file diameter Sharpening your chain and adjusting depth gauge setting General information on sharpening cutting teeth • Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the chips will be very small. If the chain is very blunt it will produce wood powder and no chips or shavings. It is very difficult to sharpen a chain correctly without the right equipment. We recommend that you use our file gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain. See instructions under the heading Technical data for information about sharpening your chain. 12 - English 115 10 82-26 Rev.2 2008-06-03
