1. 4.3.3 OIL & OIL FILTER CHANGE PROCEDURE To change the oil, proceed as follows:
2. 1. Start the engine by moving the AUTO/OFF/MANUAL switch to MANUAL and run until it is thoroughly warmed up. Then shut OFF the engine by moving the switch to the OFF position.
3. 2. Immediately after the engine shuts OFF, pull the oil drain hose (Figure 4.1) free of its retaining clip. Remove the cap from the hose and drain the oil into a suitable container.
4. 3. After the oil has drained, replace the cap onto the end of the oil drain hose. Retain the hose in the clip. Change the engine oil filter as follows:
5. 1. With the oil drained, remove the old oil filter by turning it counterclockwise.
6. 2. Apply a light coating of clean engine oil to the gasket of the new filter. See the Specifications section for recommended filter.
7. 3. Screw the new filter on by hand until its gasket lightly contacts the oil filter adapter. Then, tighten the filter an additional 3/4 to one turn (Figure 3.4).
8. 4. Refill with the proper recommended oil (see the Engine Oil Recommendations section). See the Specifications section for oil capacities.
9. 5. Start the engine, run for one (1) minute, and check for leaks.
10. 6. Shutdown and recheck oil level, add as needed. DO NOT OVER FILL.
11. 7. Reset the AUTO/OFF/MANUAL switch to the AUTO position.
