Change Engine Oil and Replace FilterIMPORTANT: If fuel sulfur content exceeds 0.5 percent, change engine oil at 1/2 the normal interval. If engine has not run 250 hours before the season changes, change oil.
1. Run engine to warm oil. Park machine on a level surface. Engage park brake. (See Prepare Machine for Maintenance in Periodic Maintenance chapter.) NOTE: Dispose of waste oil properly. 2. Remove engine oil drain plug (A). Allow oil to drain into a container. 3. Using a suitable filter wrench, turn engine oil filter (B) counterclockwise and remove from base. Clean mounting surfaces of base as necessary. 4. Apply a thin film of oil to sealing ring on new engine oil filter, and install by turning new filter clockwise by hand until gasket touches mounting surface.
