of the pump). Remove the key.
9) After 3 seconds reinsert the key in the engine shut-o switch (the starter switches on). Under the
cap of the mounting tool you should see a spark on the spark plug electrode.
Remark: In daylight it may be more dicult to see the spark. It does not have to be one spark but
you can see more tiny sparks.
Warning: The spark test can be repeated maximum ten times. Overusing the starter may
cause its overheating and damaging.
DIAGNOSTICS
A) If the spark plug does not spark, proceed according to the table on page 51 - TROUBLE-
SHOOTING, 1st line highlighted dark.
B) If the spark plug sparks after the engine shut-o key is pulled out, proceed according to the
table on page 51 - TROUBLESHOOTING, 2nd line highlighted dark

ICU charging and insert the connector in the blind plug, remove the cap from the spark plug.
12) Remove the plug from the boot and if it is not faulty, insert it back in the engine seat. FIRST
SCREW THE SPARK PLUG IN BY HAND in order not to damage the thread. When the spark plug
is in the seat, tighten it carefully with a spark plug spanner. If the spark plug is brand new, tighten
it with a spanner by 2/3 of a turn. If the spark plug has been used before, tighten it only by 1/8 –
