MAINTENANCE 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.
