ENGINE MAINTENANCE

Engine Oil Change
Drain the oil while the engine is warm. Warm oil drains quickly and
completely.
1. Put the throttle lever in the STOP position and turn the fuel valve
OFF. This will reduce the possibility of fuel leakage (page 5).
2. Wipe the oil filler area clean, and then remove the oil filler
cap/dipstick.

3. Place a suitable container
next to the mower to catch
the used oil, and 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 pour it down a drain.
4. Fill with the recommended oil
(page 6). Do not overfill.
Measure the oil level as shown.
5. After changing the engine oil
and before starting the engine,
check the oil level with the
mower on a level surface:
a. Remove the filler
cap/dipstick [1].
b. Wipe the dipstick clean.
c. Insert and remove the
dipstick without screwing
it into the filler neck.
Check the oil level shown
on the dipstick.
d. If the oil level is below
the low level mark [3],
add oil to reach the high
limit mark [2] on the
dipstick. Do not overfill. If
the engine is overfilled,
the excess oil may get
transferred to the air
cleaner housing and air
cleaner filter.
NOTICE
Running the engine with a low oil level can cause engine
damage.
e. Screw in the filler cap/dipstick securely.
Air Cleaner Service
A dirty air filter will restrict air flow to the carburetor, reducing engine
performance. If you operate the mower in very dusty areas, clean the
air filter more often than specified in the MAINTENANCE SCHEDULE
(page 15).
NOTICE
Operating the engine without an air filter, or with a damaged filter, will
allow dirt to enter the engine, causing rapid engine wear. This type of
damage is not covered by the warranty.
