Spark Plug Cleaning

Sufficiently apply the brake cleaner to the plug end.
NOTE: Repeatedly applying the brake cleaner is acceptable during the cleaning.
Using special tool MB992273, intensively clean the electrode for one to two 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 two minutes for cleaning.
After the cleaning, sufficiently remove and then dry both of the carbon and the brake cleaner on the plug, using a waste cloth or air blowing.
