Electronic governor

To set the engine speed

Ensure that the speed control lever (I3) on the fuel injection pump is held in the xed position and that

adjustment screws are both locked.

Set the screw (I2) to position 30 on the dial.

Note: The settings on the dial are in increments of 10.

Turn the adjustment screw (I1) for the engine speed, in a counter-clockwise direction 20 complete turns.

Then turn the screw in a clockwise direction 5 complete turns.

Start the engine and allow it to reach its normal temperature of operation. Initially, the engine speed will

be low. To increase the speed of the engine, gradually turn the speed adjustment screw (I1) in a clockwise

direction, until the correct engine speed is obtained.

Note: As load is applied to or removed from the engine, the engine speed will be electronically governed to

within ±0.25%. If this does not happen, further adjustments will be necessary.

If the time taken is too long for the engine to return to its correct speed, turn the adjustment screw (I2)

gradually in a clockwise direction, to a position just above 30 on the dial.

Apply a load to the engine and check that the speed and governing are correct. If necessary, repeat operation

If the time taken is too quick and the engine is erratic, turn the adjustment screw (I2) gradually in a counter-

clockwise direction, to a position just below 30 on the dial.

Apply load to the engine and check that the speed and governing are correct. If necessary, repeat operation

Note: It may be necessary to make further adjustments to the screws (I1) and (I2) until the correct speed and

governing are obtained.

Caution: Any adjustments to these screws must be made gradually.
