2. Blow candle wells the compressed air to avoid dirt hit in the engine cylinder at a candle reversing.

3. Turn out a candle...	4.... also take it from a candle well.

Good advice

If the turned-out candle remained in a well of a head of the block of cylinders, she can be taken, having put on a tip of a high-voltage wire a candle.

Note Examine a candle and estimate its condition on appearance (see. «Diagnostics of a condition of the engine on appearance of spark plugs»).

5. Check round shchupy gaps between candle electrodes. They should make 0,6–1,6 mm.

6. If gaps differ from the specified value, adjust them, turning in a lateral electrode.

Prevention Regulate a gap only a podgibaniye of a lateral electrode. Any bend of the central electrode will lead to breakage of an insulator of a candle.

7. At installation of spark plugs screw them at first a hand (without a vorotka), and then tighten a key the moment of 10-14 N · m.
