SAE 30: 40 °F and higher (5 °C and higher) is good for all
purpose use above 40°F, use below 40°F will cause hard
starting.
10W-30: 0 to 100 °F (-18 to 38 °C) is better for varying
temperature conditions. This grade of oil improves cold
weather starting, but may increase oil consumption at 80°F
(27°C) or higher.
Synthetic 5W-30: -20 to 120 °F (-30 to 40 °C) provides
the best protection at all temperatures as well as improved
starting with less oil consumption.
5W-30: 40 °F and below (5 °C and below) is recommended
for winter use, and works best in cold conditions.
Checking Oil Level
Oil level should be checked prior to each use or at least
every 5 hours of operation. Keep oil level maintained.
1. Make sure generator is on a level surface.
2. Clean area around oil fill and remove oil fill cap.
3. Verify oil is at the point of overflowing at oil fill
opening.
4. Replace and tighten oil fill cap.
Adding Engine Oil
1. Make sure generator is on a level surface.
2. Check oil level as described in Checking Oil Level.
3. If needed, slowly pour oil into oil fill opening to the
point of overflowing at oil fill.
4. Replace and tighten oil fill cap.
Changing Engine Oil
Change the oil after the first 5 hours of operation. Change
oil every 50 hours thereafter. If you are using your
generator under extremely dirty or dusty conditions, or in
extremely hot weather, change the oil more often.

USED OIL TO COLLECTION CENTERS.
Change the oil while the engine is still warm from running,
as follows:
1. Make sure unit is on a level surface.
2. Disconnect the spark plug wire from the spark plug
and place the wire where it cannot contact spark plug.
3. Clean area around oil drain plug (A). The oil drain
plug is located at base of engine, opposite carburetor
(Figure 11).
4. Remove oil drain plug and drain oil completely into a
suitable container.
5. Reinstall oil drain plug and tighten securely. Remove
oil fill cap.
6. Slowly pour oil (about 28 oz.) into oil fill
opening (B) to the point of overflowing (C) at oil fill
cap (Figure 11). DO NOT overfill.
7. Reinstall oil fill cap. Finger tighten cap securely.
8. Wipe up any spilled oil.
