The tachometer specifies number of turns of the engine in thousands of turns/min. |
Watch the indication of a tachometer at gear shifting to avoid an engine overload at increase of number of turns above the nominal.
The movement on big turns of the engine results in its premature wear and to the increased fuel consumption. Remember that the number of turns of the engine are lower, the profitability is higher.
Prevention
The driving when the arrow of a tachometer is in a red zone is not allowed, otherwise the engine quickly fails.
