Not low enough decreases cutting ability. . If cutter teeth have hit hard objects such as nails and stones, or have been abraded by mud or sand on the wood, have service dealer sharpen chain. NOTE: Inspect the drive sprocket for wear or damage when replacing the chain. If signs of wear or damage are present in the areas indicated, have the drive sprocket replaced by a Craftsman Service dealer. How to Sharpen the Cutters See Figures 33 - 34. Be careful to file all cutters to the specified angles and to the same length, as fast cutting can be obtained only when all cutters are uniform. . Wear gloves for protection. Properly tension the chain prior to sharpening. Refer to Chain Tension Section earlier in this manual. Do all of your filing at the mid-point of the bar. . Use a 5/32 in. diameter round file and holder. . Keep the file level with the top plate of the tooth. Do not let the file dip or rock. . Using light but firm pressure, stroke towards the front corner of the tooth. . Lift file away from the steel on each return stroke. . Put a few firm strokes on every tooth. File all left hand cutters in one direction. Then move to the other side and file the right hand cutters in the opposite direction. Occasionally remove filings from the file with a wire brush. WARNING: Improper chain sharpening increases the potential of kickback. WARNING: Failure to replace or repair damaged chain can cause serious injury. WARNING: The saw chain is very sharp, always wear protective gloves when performing maintenance to the chain. Top Plate Filing Angle See Figure 35. . CORRECT 30° - File holders are marked with guide marks to align file properly to produce correct top plate angle. . LESS THAN 30° - For Cross Cutting. . MORE THAN 30° - Feathered Edge Dulls Quickly. MAINTENANCE Side Plate Angle See Figure 36. . CORRECT - 80° Produced automatically if correct diameter file is used in file holder. . HOOK - “Grabs” and dulls quickly. Increases potential of KICKBACK. Results from using a file with diameter too small, or file held too low. . 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 37 - 39. . The Raker (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. GUIDE BAR MAINTENANCE See Figure 40. 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. Reversing the guide bar . Remove the chain from the bar and turn the bar over. NOTE: Bottom of bar should not be on top. . Replace the chain on the bar. Refer to Assembling the Bar and Chain earlier in this manual for specific information. . Tighten the screw with your finger. . From the finger-tight position, tighten the screw an additional 3/4 of a turn using a wrench. WARNING: Remove the battery pack and make sure the chain has stopped before you do any work or making any adjustments on the saw. Failure to do so may result in accidental starting and possible serious injury. TRANSPORTING AND STORING See Figure 41. . 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 chain cover 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. MAINTENANCE TROUBLESHOOTING Problem Cause S...
