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 8). 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 34.
NOTICE
Using nondetergent oil can
shorten the engine's service
life, and using 2-stroke oil
can damage the engine.
