At temperature more low - 25 C (-13F), it is recommended to use candles with a sign (*) for the best work of the engine.



  1. Establish a candle () ignitions (3) and tighten them according to the specified twisting moment of an inhaling. An inhaling twisting moment: a candle () ignitions: 25 Н•м (2.5 kg th, 18.0 pounds-foots).
  2. Establish assemblage of the coil of ignition (2) reliably.
  3. Tighten a bolt of the coil of ignition (1), and then connect муфту ignition coils.
