To compress the spring and release tension on the belt, push the blade bearing housing back toward the engine (see Figure 12). 6. Carefully note the twist of the belt around the engine pulley. Remove the old belt. Replace with an original equipment belt. 7. To install a new belt, reverse the above steps. Make sure to twist the new belt as shown in Figure 12.

This will not generally affect its function. The blade is designed to not require sharpening. Do not attempt to sharpen the blade. The blade is also reversible. If nicks or dents are excessive, remove the blade and turn it around. This will provide a fresh cutting edge. Replace the blade if both sides are worn or damaged. WARNING: Do not sharpen the blade. Sharpening can damage the blade and cause it to break, which can cause injury to yourself or to others. To replace the blade, follow the steps below. 1. Disconnect the spark plug wire from the spark plug. 2. Remove the blade locknut that holds the blade to the drive shaft. WARNING: To remove or tighten the blade locknut, always use the method shown in Figure 13. Always position the holding wrench on the nut behind the blade. 3. Remove the blade. 4. Install a new blade and blade locknut. Tighten the blade locknut to a torque of 40–45 foot pounds.

Never store in an enclosed, poorly ventilated area where fumes could reach an open flame, a spark or a pilot light as on a furnace, water heater or clothes dryer. WARNING: Do not remove gasoline while inside a building, near a fire, or while you smoke. Gasoline fumes can cause an explosion or a fire. When the Edger is put in storage for thirty days or more, follow the steps below to make sure the Edger is in good condition the following season. 1. Drain the fuel tank. 2. Let the engine run until it is out of gasoline. 3. Drain the oil from the warm engine. Fill the engine crankcase with new oil. 4. Remove the spark plug from the cylinder. Pour one ounce of oil into the cylinder. Slowly pull the recoil–start grip so that the oil will protect the cylinder. Install a new spark plug in the cylinder. 5. Clean the dirt and debris from the cylinder cooling fins and the engine housing. 6. Completely clean the Edger. 7. Check the Edger for worn or damaged parts. Tighten all loose hardware. 8. Apply a small amount of engine oil to all moving parts, particularly the wheels. 9. Put the unit in a building that has good ventilation. 10. Cover the Edger with a suitable protective cover that does not retain moisture. Do not use plastic. IMPORTANT: Never cover the Edger while the engine and exhaust areas are still warm. NOTE: A yearly checkup or tune–up by an Authorized Service Center is a good way to make sure that your Edger will provide maximum performance for the next season.
