6.1 Preparatory Data
Precautions on operation
1. Ignition system inspection: please perform inspection in the sequence listed in the fault diagnosis table.
2. Ignition system uses electronic-type automatic timing device, which is solidified in the CDI assembly, so it
is unnecessary to adjust the ignition time.
3. Ignition system inspection: please perform inspection in accordance with the sequence listed in the fault
diagnosis table.
4. Ignition system CDI shall not be dropped and hung, or heavily knocked (this is also the main reason for its
failure). Pay special attention to this while removing it.
5. Most of the ignition system problem due to poor contact of sockets. Please check first if parts of the
connector are well contacted.
6. Check if heat value of spark plug is proper. Improper spark plug may result in unsmooth engine running or
burn of spark plug.
7. The maximum voltage is taken to introduce inspection items in this Part. Inspection methods for impedance
value of ignition coil are also recorded and judged.
8. Check ignition switch according to the continuity test table.
9. Remove alternator and stator on operation instructions.
