Electrode condition
Check the electrodes for wear or burning. If they are
extremely used or burnt, substitute the spark plugs. Also
substitute the spark plugs in the case of breakage of the
B
ceramic isolation or damage to threading.
When the spark plugs are renewed, check the
thread pitch size and the length of the thread. If
the threading is too short, carbon deposits will
be placed on the threading of the cylinder head
plughole thereby risking damage to the engine.
Manually screw the spark plugs into their seats to
avoid damaging the threads of the motor head. Tighten
to the prescribed tightening torque.
Spark plugs torque pressure: 12 N·m
