a Required distance between depth gauge and cutting edge When cutting softwood outside of the frost season, the distance can be increased by up to 0.2 mm (0.008"). Chain pitch Inches 1/4 P 1/4 3/8 P 0.325 3/8 0.404 (mm) (6.35) (6.35) (9.32) (8.25) (9.32) (10.26) Depth gauge Distance (a) mm (Inches) 0.45 (0.018) 0.65 (0.026) 0.65 (0.026) 0.65 (0.026) 0.65 (0.026) 0.80 (0.031) Lowering the depth gauges The depth gauge setting is lowered when the cutter is sharpened. N Check the depth gauge setting after each sharpening Saw chains with humped drive link (2) - upper part of the humped drive link (2) (with service mark) is lowered at the same time as the depth gauge of the cutter. WARNING The rest of the humped drive link must not be filed; otherwise, this could increase the tendency of the chain saw to kick back. N Rework the depth gauge so that it is flush with the file gauge 689BA051 KN English WARNING Depth gauges that are too low increase the kickback tendency of the chain saw. N Lay the file gauge on the saw chain - the highest point of the depth gauge must be flush with the file gauge N After sharpening, clean the saw chain thoroughly, removing any filings or grinding dust - lubricate the saw chain thoroughly N In the event of extended periods of disuse, store saw chains in cleaned and oiled condition 689BA052 KN 689BA044 KN 1 2 689BA061 KN N Lay the appropriate file gauge (1) for the chain pitch on the saw chain and press it against the cutter to be checked - if the depth gauge protrudes past the file gauge, the depth gauge must be reworked N Afterwards, dress the leading edge of the depth gauge parallel to the service mark (see arrow) - when doing this, be careful not to further lower the highest point of the depth gauge MS 441 C-M 49
