  1. Enter service code "1b". The following information will be displayed: the name of the model, type of engine and type of control levers.

    "1b 45 CH" is an example.

    45 - This number indicates 345B.

    C - This letter indicates a AVSpare engine.

    H - This letter indicates the type of hydraulic control levers.

    Note: When "H" is being displayed in the second position from the right, the display will indicate a "MHI mode" type of engine.

Enter service code "1A". The fine control mode switch (25) is pressed in order to move the number that is flashing to the second position from the left. The boom priority mode switch (23) is pushed until a flashing "A" appears. The third position from the left side indicates the speed dial position. The three numbers from the left will show the engine rpm that is multiplied by 10. Change the speed dial position in order to read the target rpm for the speed position.

This function is used to verify that the setting of the engine speed at each position of the engine speed dial corresponds to the factory settings of the engine speed. For the proper engine RPM, refer to the chart.
