Use a flat file and depth gauge tool to adjust the depth gauge. 1. Put the depth gauge tool above the saw chain. Detailed information regarding how to use the depth gauge tool will be found on the package of the depth gauge tool. 2. Use the flat file to file off the tip of the depth gauge that protrudes through the depth gauge tool. The depth gauge setting is correct when you no longer feel resistance as you draw the file along the depth gauge tool. To tension the saw chain Note: Check the tension of a new saw chain frequently during its running-in period. 1. Loosen the guide bar nuts that hold the clutch cover. Use the combination wrench.

Tighten the saw chain until it does not hang down from the bottom of the guide bar. (Fig. 82) 4. Tighten the guide bar nuts using the combination wrench and lift the tip of the guide bar at the same time. (Fig. 83) 5. Make sure that you can pull the saw chain round freely by hand and that it does not sag.
