Depth gauges The depth gauge determines the height at which the cutter enters the wood and thus the thickness of the chip removed. The cutting capacity and life of a saw chain are therefore influenced by the distance between the depth gauge and the cutting edge, i. e. the depth gauge setting. This selling varies according to chain pitch and must be checked with the appropriate filing gauge. The best cUlling results are obtained with the sellings listed in the table on the right. However, the depth gauge selling may be increased by 0.2 mm for cUlling softwood in mild weather conditions. As the culler is sharpened the depth gauge selling is reduced. This means the height of the depth gauge must be checked and lowered if necessary. If the depth gauge projects from the filing gauge, it must be filed down level with the gauge. On Rapid chain the depth gauge should also be rounded off to its original shape.

The essential points are correct chain tension and ample lubrication. See also "Culling Attachment". Clean the chain thoroughly in gasoline after sharpening in order to remove filings or grinding dust. Then lubricate the chain by immersing it in an oil bath. If the chain has not been used for an extended period, clean it with a brush and 34 immerse it in an oil-paraffin bath. ~tpj 1---------."
