Before Starting

Filling the Crankcase with Oil

The engine crankcase can hold 22 ounces (0.65 liters) of oil. Use only high-quality SAE 10W±30 weight detergent oil that has the American Petroleum Institute (API) service classification SH, SJ, or equivalent.

Before each use, ensure that the oil level is between the lower limit and upper limit marks on the dipstick (Fig. 5).

Note: When the crankcase is empty, pour about three-fourths of the crankcase capacity of oil in the crankcase, then follow the procedure in this section.

To add oil:

1.Move the lawn mower to a level surface.

2.Clean around the dipstick (Fig. 5).

3.Remove the dipstick by rotating the cap counterclockwise and pulling it out.

4.Wipe the dipstick clean with a clean cloth.

5.Insert the dipstick into the filler neck (but do not rotate the cap clockwise to secure it), then remove it.

6.Read the oil level on the dipstick (Fig. 5).

7.If the oil level reading is below the lower limit mark on the dipstick, remove the dipstick and slowly pour only enough oil into the filler hole to raise the oil level to the upper limit mark on the dipstick (Fig. 5).

Important Do not overfill the crankcase with oil and run the engine; engine damage will result. Drain the excess oil until the oil level reaches the upper limit mark on the dipstick.

8.Insert the dipstick into the filler neck and rotate the cap clockwise until it is tight.

Filling the Fuel Tank with Gasoline

For best results, use clean, fresh, lead-free gasoline with an octane rating of 87 or higher. To ensure freshness, purchase only the quantity of gasoline that you expect to use in 30 days. Using unleaded gasoline results in fewer combustion deposits and longer engine life.

Important Do not add oil to the gasoline.

Important Do not use methanol, gasoline containing methanol, gasohol containing more than 10% ethanol, premium gasoline, or white gas. Using these fuels can damage the engine's fuel system.

Important Do not use gasoline that is more than 30

days old.
