manual abstract
. BACKWARD SLOPE - Needs too much feed pressure, causes excessive wear to bar and chain. Results from using a file with diameter too large, or file held too high. Depth Gauge Clearance See Figure 36 - 38. . The depth gauge should be maintained at a clearance of .025 in. Use a depth gauge tool for checking the depth gauge clearances. . Every time the chain is filed, check the depth gauge clearance. Use a flat file and a depth gauge jointer to lower all gauges uniformly. Depth gauge jointers are available in .020 in. to .035 in. Use a .025 in. depth gauge jointer. After lowering each depth gauge, restore original shape by rounding the front. Be careful not to damage adjoining drive links with the edge of the file. Depth gauges must be adjusted with the flat file in the same direction the adjoining cutter was filed with the round file. Use care not to contact cutter face with flat file when adjusting depth gauges.

Fig. 36 GUIDE BAR MAINTENANCE See Figure 39. When the guide bar shows signs of wear, reverse it on the saw to distribute the wear for maximum bar life. The bar should be cleaned every day of use and checked for wear and damage. Feathering or burring of the bar rails is a normal process of bar wear. Such faults should be smoothed with a file as soon as they occur. A bar with any of the following faults should be replaced. . Wear inside the bar rails which permits the chain to lay over sideways. . Bent guide bar. . Cracked or broken rails. . Spread rails. In addition, guide bars with a sprocket at their tip must be lubricated weekly with a grease syringe to extend the guide bar life. Using a grease syringe, lubricate weekly in the lubricating hole. Turn the guide bar and check that the lubrication holes and chain groove are free from impurities. TRANSPORTING AND STORING See Figure 40. . Do not store or transport the chain saw when it is running. The chain saw should always be idle before storing or transporting. . Always place the guide bar scabbard on the bar and chain before storing or transporting the chain saw. Use caution to avoid the sharp teeth of the chain. . Clean the chain saw thoroughly before storing. Store the chain saw indoors, in a dry place that is locked and/or inaccessible to children. . Keep away from corrosive agents such as garden chemicals and de-icing salts.
