6 Place the spark plug again carefully, start screwing with your hand to avoid
the threads. Once the spark plug is threaded to the end of the thread, make the
final tightening:
New spark plugs, 1/2 turn with the spark plug spanner.
1/8 to 1/4 turn used spark plugs with spark plug spanner.
7 Install the spark plug pipette or cap and close the spark plug access cover,
fixing it with the screw.
NOTE: The spark plug must be tightened firmly. A loose spark plug may
overheat and even damage the engine. Similarly, overtightening may damage
the spark plug and, worse, the engine cylinder head thread.
