Changing Engine Oil and Filter
WARNING
Potential of cancer. Prolonged or repeated contact with used motor oil has been
shown to cause cancer in laboratory animals. Thoroughly wash exposed areas with
soap and water. (000127a)
When changing oil, it is not necessary to drain oil from reservoir.
1. Stop engine and let cool for at least 10 minutes.
2. Close valve below oil reservoir.
3. Place a container below oil drain port.
4. Remove oil drain plug.
5. Open drain valve at the engine oil pan. Verify oil level regulator valve is open.
6. Allow oil to drain completely into the container.
7. Remove oil filter and discard it. Gasket from filter might separate and become stuck to the engine. If so,
remove the gasket and discard it.
8. Before installing new oil filter, lubricate oil filter gasket with a thin film of clean engine oil.
9. Install new oil filter, turning one full turn after initial gasket contact.
10. Close engine oil drain valve and reinstall plug at the skid frame drain port.
11. Remove oil fill cap on engine valve cover and add fresh oil. See General Information for oil capacity and oil
type.
12. Check the oil dipstick. Oil level should be between ADD and FULL marks.
13. Open oil reservoir valve.
14. Top off the oil in the reservoir.
There is no need to run the unit and re-check the oil level. The filter automatically fills up with oil and the oil switch
allows the proper amount of oil to supply the engine until full.
