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 4).
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).
Refill amount: 0.35 ~ 0.40 L
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 properly maintained air filter will help prevent dirt from entering your
engine. Dirt entering the carburetor can be drawn into small passages
in the carburetor and cause premature engine wear. These small
passages can become blocked, causing starting or running problems.
Always use an air filter specified for your engine to ensure it seals and
performs as designed. You will need to clean the filter more frequently
if you operate the engine in very dusty conditions.
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.
1. Press down on the
air cleaner cover [1]
tabs, and then
remove the cover.
2. Remove the filter [2]
from the air cleaner
housing [3].
3. Inspect the filter, and
replace it if it is
damaged.
4. Clean the filter by
tapping the filter
several times on a hard surface to remove dirt, or blow
compressed air (not exceeding 207 kPa) through the filter from the
inside. Never try to brush off dirt; brushing will force dirt into the
fibers.
5. Wipe dirt from the inside of the air cleaner housing and cover,
using a moist rag. Be careful to prevent dirt from entering the air
duct that leads to the carburetor.
6. Reinstall the filter and cover.
Spark Plug Service
Recommended spark plugs:
NOTICE
Incorrect spark plugs can cause engine damage.
For good performance, the spark plug [1] must be properly gapped
and free of deposits.
1. Disconnect the spark plug cap [2],
and remove any dirt from around the
[1]
spark plug area.
[2]
[3]
2. Remove the spark plug with a spark
plug wrench [3].
