(Check that pump flow rate and engine speed have been changed.)
IMPORTANT: After adjusting the engine speed and flow rate to the attachment, turn the engine learning switch to neutral. If the engine is started with the engine learning switch in the engine learning position, the MC will not control the engine, pumps, and valves so that change in the pump flow rate and the engine speed cannot be checked.
1. Turn the key switch OFF.
2. Wait approx. 10 seconds.
3. Turn the engine learning switch to neutral.
4. Disconnect the Dr. ZX. connector (When monitoring with Dr. ZX, pass this step.)
5. Turn the key switch ON.
6. Start the engine.
7. Check operational performances of the machine.
