Exhaust gas leaks from the exhaust system connections fitted with
gaskets are not allowed and shall be eliminated on the first occasion.
Stuck nuts shall be tightened (see Appendix 2) with preliminary wetting
of thread connections with special liquids or kerosene.
When the feed system or the ignition system is faulty, a lot of unburnt
hydrocarbons ingress into the converter and due to this, the temperature
in the converter can rise above the admissible limit and the converter will
fail. So, special attention shall be paid to operation of the feed system
and the ignition system. Three-cylinder-based operation of the engine
is prohibited even for a short period of time.
