AIR CLEANER MAINTENANCE

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.

ENGINE OIL CHANGE

Drain the oil while the engine is warm. Warm oil
drains quickly and completely.
1. HYEA, VYEA types:
Put the throttle lever in the STOP position and turn the fuel valve OFF.
This will reduce the possibility of fuel leakage (page 7).
HZEA type:
Turn the key OFF and turn the fuel valve OFF. This will reduce the
possibility of fuel leakage (page 7).
VKEA type:
Turn the fuel valve OFF. This will reduce the possibility of fuel leakage
(page 7).
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 7).
Refill amount: 0.35 ~ 0.40 L
Do not overfill. Measure the oil level as
shown.

SAFETY
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.

CHECKING THE SPARK PLUG

Required 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
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.
4. Measure the spark plug electrode
gap with a suitable gauge. The gap
should be 0.7 ~ 0.8 mm. Correct the
gap, if necessary, by carefully
bending the side electrode.
5. Install the spark plug carefully, by
hand, to avoid cross-threading.
6. After the spark plug seats, tighten
with a spark plug wrench to
compress the washer.
If reinstalling the old spark plug,
tighten 1/8 to 1/4 turn after the spark plug seats.
If installing a new spark plug, tighten 1/2 turn after the spark plug seats
to compress the washer [3].
TORQUE: 20 N•m
NOTICE
A loose spark plug can overheat and damage the engine. Overtightening
the spark plug can damage the threads in the cylinder head.
7. Install the spark plug cap onto the spark plug.
