After removal from the engine spark, make sure there were no
mechanical damage to the heat insulating housing 5 and the electrode spark.
In the presence of soot on the heat insulator cone candle clean
on the blaster, rinse brush in clean gasoline and blow
compressed air. Then check the gap between the electrodes, which
should be in the range 0,8-0,95 mm. When adjusting the gap is not allowed
click on the central electrode, as this may damage the
Check of the candle is made of pressure on the special
instrument. In the healthy spark at a pressure of 8.9 kgf/cm2 should be provided
uninterrupted sparking between the electrodes.
At a pressure of 10 kgf / cm, a new candle must be completely airtight -
air must be held at the junctions of the central electrode
with the insulator and the insulator housing.
