1. Ensure that the fuel tank contains little or no fuel so
that fuel does not leak out when you tip the mower
onto its side.
2. Run the engine a few minutes before changing the
oil to warm it.
Note: Warm oil flows better and carries more
contaminants.
3. Disconnect the wire from the spark plug. Refer to
Preparing for Maintenance.
4. Remove the dipstick.
5. Tip the mower onto its side, with the dipstick down,
to drain the used oil out through the oil fill tube
(Figure 21).
6. Return the mower to the operating position.
7. Slowly pour oil into the oil fill hole, wait a few
minutes, and check the oil level on the dipstick by
wiping the dipstick clean and then inserting, but not
screwing in, the oil fill cap into the hole.
Note: Max. fill: 20 oz. (0.59 l), type: SAE 30
or SAE 10W-30 detergent oil with an API service
classification of SF, SG, SH, SJ, SL, or higher.
Note: Fill the engine crankcase with oil until the
dipstick indicates that the engine oil level is correct
as shown in (Figure 22). If you overfill the engine
with oil, remove the excess oil as directed in 5.
