If the filter is damaged or is wet with oil or fuel,
replace it.

If the filter is dirty, tap it on a hard surface several
times or blow the debris outward from the interior
of the filter using compressed air at less than 207
kPa (30 psi).
Note: Do not brush or blow dirt from the outside

Max. fill: 0.59 L (20 oz), type: SAE 30 detergent oil with an
API service classification of SF, SG, SH, SJ, SL, or higher.

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 (page 17).
4. Tip the mower onto its side, with the dipstick down,
until the upper handle rests on the ground.
5. Set an oil-drain pan under the dipstick.
6. Remove the dipstick and drain the used oil into an
oil-drain pan (Figure 33).
7. After draining the used oil, return the mower to the
operating position.
8. Remove the dipstick (Figure 34) and pour about 3/4 of
the crankcase capacity of oil into the oil-fill tube.
