Before Starting
Filling the Crankcase with Oil
The crankcase can hold 26 ounces (0.77 liters) of oil (with
the oil filter installed) and 22 ounces (0.65 liters) of oil
without the oil filter installed. Use only high-quality, SAE
30 or SAE 10W30 weight detergent oil that has the
American Petroleum Institute (API) service classification
SF, SG, SH, or SJ.
Note: Before each use, ensure that the oil level is between
the Add and Full marks on the dipstick (Fig. 7).

To add oil:
1. Move the lawn mower onto a level surface.
2. Clean around the dipstick.
3. Remove the dipstick by rotating the cap
counterclockwise and pulling it out.
4. Wipe the dipstick clean with a clean cloth.
5. Fully insert the dipstick into the filler neck, then remove
it.
Note: To ensure an accurate oil level reading, you must
fully install the dipstick.
6. Read the oil level on the dipstick (Fig. 7).
7. If the oil level reading is below the Add mark on the
dipstick, slowly pour only enough oil into the oil fill
tube to raise the oil level to the Full mark on the
dipstick.
Important
Do not overfill the crankcase with oil and
run the engine; engine damage will result. Drain the excess
oil until the oil level on the dipstick reads Full.
8. Insert the dipstick into the oil fill tube and rotate the cap
clockwise until it is tight.
