Maintenance and care
■
Unscrew the spark plug (18/3) using a
spark plug spanner (18/2).
2. Assessing the condition of the spark plug:
■
If the spark plug is reddish-brown: The
engine is working correctly and the spark
plug is in order. If necessary: Carefully
brush the spark plug clean using a fine
wire brush (18/4).
■
If the spark plug is sooty, oily, encrusted,
melted or bridged: The spark plug is de-
fective. Replace the spark plug with a
new spark plug. Use the specified spark
plug type (see chapter 13 "Technical da-
ta", page 42).
■
If, after a short period of operation, the
spark plug is defective again, the engine
and the carburettor settings must be
checked by an authorised service work-
shop.
3. Check the electrode spacing:
■
Use a feeler gauge (18/5) to check that
the electrode gap (18/6) is 0.6 – 0.7 mm.
If not, carefully tap the electrodes closer
together or carefully bend them apart.
4. If the specified interval is reached or the
spark plug is defective:
■
Replace the spark plug with a new spark
plug. Use the specified spark plug type
(see chapter 13 "Technical data",
page 42).
