Changing Engine Oil and Filter

Avoid damage! Operating in extreme conditions may require more frequent service intervals:

• Engine components may become dirty or plugged when operating in extreme heat, dust or other severe conditions.
• Engine oil can degrade if machine is operated constantly at slow or low engine speeds or for frequent short periods of time.

1. Run engine to warm oil.

2. Park machine safely on level surface. (See Parking Safely in the SAFETY section.)

3. Lift hood.

   Prepare to drain oil:

   1. Model X330 —Disconnect oil drain hose (A) from side of engine and lower hose.

   2. Models X350, X354, X370, X380, X384, X390, X394 — Put drain pan under drain valve (A).

5. Drain oil:

   1. Model X330 — Remove oil drain cap (B). Carefully lower oil drain hose into an approved container and allow oil to drain completely.

   2. Models X350, X354, X370, X380, X384, X390, X394 — Remove drain cap (B) and drain oil into drain pan. Allow oil to drain completely.

6. Remove dipstick (C).

7. Wipe dirt from around oil filter (D).

8. Place a drain pan or funnel under oil filter tray.

9. Remove old filter and wipe off filter tray.

10. Put a light coat of fresh, clean oil on filter gasket.

11. Install replacement oil filter by turning oil filter to the right (clockwise) until the rubber gasket contacts filter base. Tighten filter an additional one-half turn.

12. Install and tighten drain cap.

13. Model X330 — attach drain hose to side of engine.

14. Avoid damage! Do not overfill. Some residual oil could remain in engine after draining. Overfilling can cause smoking, hard starting, fouling of spark plug, and oil saturation of air filter.

    Add oil slowly and stop to check oil level every few ounces to avoid overfilling. Add oil no higher than FULL mark on dipstick. Do not overfill.

    • Model X330 — Begin with approximately 1.9 L (2 qt).
    • Models X350, X354, X370 — Begin with approximately 1.7 L (1.8 qt).
    • Models X380, X384, X390, X394 — Begin with approximately 2.1 L (2.2 qt).
    
    

15. Install dipstick.

16. Start and run engine at idle to check for leaks. Stop engine. Fix any leaks before operating.

17. Check oil level. Add oil if necessary.
