Under dusty condition, element should be cleaned more frequently. If your edger has a Kawasaki engine: Snap cover off air cleaner assembly. Remove element, shake out, and wash in kerosene. Allow filter to dry. Reinstall the element in air cleaner body. Make sure that the surface marked INSIDE faces carburetor. Note: Do not oil filter element. If your edger has a Briggs and Stratton engine: Remove screw securing air cleaner assembly. Remove top cover. Remove element, shake out, and wash in kerosene then allow to dry. Reinstall element in air cleaner body making sure that surface marked INSIDE faces carburetor. Assembly Periodically check that all bolts are tight, especially engine mounting bolts and blade guard mounting bolts. Grease edger periodically at points shown on Figure 13. (use lithium based grease) Note: The spindle bearings are sealed and permanently lubricated. They should require no maintenance. 8 Troubleshooting Guide Problem Engine fails to start Hard starting or loss of power Operation erratic Engine skips at high speed Engine idles poorly Cause Fuel level is low.
