1.Measure the insulation
resistance of the spark plug. If the insulation resistance
of the spark plug is under the limited value, clean the
spark plug (Refer to ). 2.After
cleaning, measure the insulation resistance again. Replace
the plug unless it is within the limited
value. Limit: Minimum 10 MΩ

2.Using special tool spark
plug brush (MB992273), intensively clean the electrode for 1
to 2 minutes.
note |
Even if using strong force,
the electrode is not damaged.
|
note |
In case of insufficient
cleaning, it is permissible to take longer than
2 minutes for cleaning.
