Removing the spark plug
¨
Remove the housing cover on the right, see “7.4.2.1 Removing the housing cover” on
page 109 .
¨ Open the rubber tab next to the fuel tank’s fill
level indicator.
¨ Remove any dirt that could drop down into the
combustion chamber after the spark plug is
removed.
¨ In the housing, pull the spark plug connector
off the spark plug. Use a screwdriver as a lever
to do this if necessary.
¨ Guide the spark plug spanner into the housing
through the opening next to the fuel tank’s fill
level indicator.
¨ Loosen and remove the spark plug.

Checking and cleaning the spark plug
¨
Visually check that the spark plug meets the following criteria:
– The porcelain body of the insulator is undamaged. No visible cracks or splintering.
ATTENTION!
A hairline crack in the insulator cannot be seen in a visual check but can result
in faults during operation. You should replace the spark plug in this case.
– The electrodes are dry and free of deposits. Strong ignition sparks require the
electrode edges to be clean and sharp.
– The electrode gap is as specified, see “ Checking and adjusting the electrode gap” on
page 111 .
– The spark plug produces a strong ignition spark, see “ Testing the spark strength” on
page 112 .
¨
Use a fluff-free cleaning cloth to remove oil and petrol from the spark plug.
¨
Use a wire brush to remove minor contamination from the electrodes.
¨ If necessary, use a knife to scratch off stubborn deposits.
ATTENTION!
Tools and cleaning agents that have an abrasive effect can make the electrode
edges round and impair the spark strength.
Checking and adjusting the electrode gap
¨ Use a spark plug gauge to measure the spark gap
between the two electrodes.
The nominal clearance is 0.6 - 0.7 mm.
0,6 – 0,7 mm
¨
Carefully bend the outer electrode to set the correct clearance. The blade of the gauge
should scrape gently against the electrodes when it is pulled out.
