Engine Oil Change
Drain the used oil while the engine is warm. Warm oil drains quickly
and completely.
1. Turn the fuel valve OFF (page 19). This will reduce the possibility
of fuel leakage.
2. Wipe the oil filler area clean, then remove the oil filler cap/dipstick.
3. Place a suitable container next to
the mower to catch the used oil,
then tilt the mower on its right side.
The used oil will drain through the
filler neck. Allow the oil to drain
completely.
Please dispose of used motor oil
and the containers in a manner that
is compatible with the environment. We suggest you take it in a
sealed container to your local recycling center or service station for
reclamation. Do not throw it in the trash, pour it on the ground or
down a drain.
4. Fill with the recommended
oil. Do not overfill. Allow a
couple of minutes for the oil
to settle in the engine, then
measure the oil level as
shown on page 32.
NOTICE
Using nondetergent oil can shorten the engine's service life, and
using 2-stroke oil can damage the engine.
