Use and maintenance
Start the engine.
The values may be displayed in three different ways: one numeric format and two graphic formats; to select the desired display
type, press the “Value display” icon (F).
The measured value is indicated alongside the letter (A) or (C) identifying the cable used for the measurement: i.e. if you used
connector (A) of the cable (3), the measured value will be displayed next to the letter (A) on the screen.
Oil pressure test values:
Warm engine
(Minimum oil temperature = 80 °C)
1100 to 1300 rpm
greater than 0.8 bar
3500 ÷ 4000 rpm
greater than 4 bar
Important
The maximum pressure must never exceed 6.0 bar.
Excessively high pressure may indicate that the relief valve is stuck. Excessively low pressure, on the other hand, may be caused
by the relief valve being stuck in the open position, the relief valve spring being too weak, or a faulty oil pump. Other causes are
excessively worn seals and gaskets or a badly worn engine.
