Engine Oil Change; Checking The Spark Plug - Honda HRX476C Manual De Instrucciones

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. Tip the mower on its side.
2. Place a receptacle [1] under
the casing filler tube hole.
And rock the mower on the
right side.
3. Remove the oil filler cap [2].
4. Return the mower to the
upright position on its wheels
when the casing is completely
empty.
5. Fill up [3] to "high level" [4]
using the recommended oil
(see page 6).
6. Screw the filler cap fully on to
avoid the risk of leaks.
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 plugs: NGK - BPR5ES
CAUTION:
• Use only recommended spark plugs. Using spark plugs 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 very hot.
1. Pull off spark plug cap [6] and remove spark plug [7] using a plug
spanner [8].

2. Carefully inspect the spark plug. Replace the plug if there are a
lot of deposits or if the insulator is cracked or broken.
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. Check that the sealing washer is in good condition; then screw
the plug down by hand until finger tight and correctly seated.
5. Using a plug spanner, give an additional 1/2 turn for a new spark
plug, to compress the washer. If you refit the same plug, just
1/8 to 1/4 turn will do from the finger tight position.
6. Refit the spark plug cap.
CAUTION:
• The spark plug must be correctly tightened. A plug incorrectly
screwed down can become very hot and damage the engine.
MAINTENANCE OF SPARK
ARRESTER
(OPTIONAL PART)
(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 mower 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 three flange
bolts [9] from the muffler
protector [10] and remove
the muffler protector.
2. Remove the two 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.
