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.
•Bar groove width (inches/mm). The groove in the bar must match the width of the chain drive links.
•Chain oil hole and hole for chain tensioner. The bar must be matched to the chain saw design.

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.
•A sharp chain eats its way through the wood and produces long, thick chips or shavings.
•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).
When you sharpen a cutting tooth there are four important factors to remember.
