ENGINE OIL CHANGE
Drain the oil while the engine is still hot, so that
the oil drains quickly and completely.
CAUTION:
• Used engine oil can cause skin cancer if it remains in contact with
the skin for long periods.
Although this is highly unlikely unless you handle used oil every
day, we recommend that you wash your hands thoroughly with
soap and water each time you handle used engine oil.
1. Put the throttle lever in the
STOP position and turn the
fuel valve OFF. This will
reduce the possibility of fuel
leakage (
see page 9
).
2. Wipe the oil filler area clean,
and then remove the oil filler
cap/dipstick [1].
3. Place a suitable container [2]
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.
4. Fill with the recommended oil
(
see page 7
). Do not overfill.
Engine oil capacity: 0.40
ℓ
5. After changing the engine oil
and before starting the
engine, check the oil level
with the mower on a level
surface. If the oil level is
below the low level mark [3],
add oil to reach the high level
mark [4] on the dipstick.
6. Screw in the oil filler cap/dipstick securely.
NOTE:
The used engine oil must be disposed of in a manner which
respects the environment.
We recommend that you take it to a service station which will ensure
that it is recycled. Never dispose of used engine oil in dustbins or
pour it away on the ground, in the gutter or down the drains.
CHECKING THE SPARK PLUG
Recommended plug: NGK - BPR5ES
CAUTION:
• Use only recommended spark plug. Using spark plug with
inappropriate temperature ranges may damage the engine.
If the engine has just been run, do not touch the muffler and the
spark plug which will still be hot.
1. Pull off spark plug cap [5] and remove spark plug [6] using a plug
wrench [7].
2. 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.
3. Measure the plug gap using a set of feeler gauges; the gap must
be between 0.7 and 0.8 mm. If adjustment is necessary,
carefully bend the side electrode.
4. Install the spark plug carefully, by hand, to avoid
cross-threading.
5. 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 [8].
6. Refit the spark plug cap.
CAUTION:
• A loose spark plug can overheat and damage the engine.
Overtightening the spark plug can damage the threads in the
cylinder head.
MAINTENANCE OF SPARK
ARRESTER
(In Europe and other countries where the machinery directive
2006/42/EC is enforced, this cleaning should be done by your
servicing dealer).
If the lawnmower has just been run, the silencer will still be very
hot. Allow it to cool down before carrying out this operation.
In some regions, it is prohibited to operate an engine without a
spark arrester.
1. Remove the 3 flange bolts [9]
from the muffler protector
[10] and remove the muffler
protector.
2. Remove the 2 tapping
screws [11] from the spark
arrester [12] and remove the
spark arrester from the
muffler.
3. Check the carbon deposits
around the exhaust port and
spark arrester. Clean if
necessary.
4. Replace the spark arrester if
there are any breaks or
tears.
5. Install the spark arrester [12]
and muffler protector [10] in
the reverse order of removal.
