Service candles

Deposits between the porcelain insulator of the central electrode and the body of the candle should be removed if possible sandblasting using spark tester. When screwing the spark required to ensure that pre-carving was thoroughly cleaned. Since the service life of spark is at least 15 000 km, enough to clean them every 10 000 km. When screwing candle should pay attention to the fact that they are tightened too much, otherwise you can only damage the sealing washer. In order not to damage the threads of spark, can not exceed the tightening torque of 25 Nm.
