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 (HZE: turn the key OFF)
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
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
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 spark
plug area.
2. Remove the spark plug
with a spark plug wrench.
3. Inspect the spark plug.
Replace it if the electrodes
are worn or if the insulator
is cracked or chipped.
Clean the spark plug with a
wire brush if you are going
to reuse it.
