1. CHANGE IN PARTS IN THE MAIN CIRCUIT BOARD AND POWER SUPPLY
PWB (TO IMPROVE PRODUCTIVITY).
2. CHANGE IN THE LENGTH OF THE HL HARNESS (MARGIN UP).
3. TROUBLE SHOOTING PS SOLENOID MALFUNCTION (MARGIN UP).
1. Change in parts in the main circuit board and power supply PWB (to improve
productivity)
1.Model name: Z-20, 23, 25, 27
2.General: Some of the parts in the main circuit board and the power supply PWB have been
changed to improve productivity. The parts list should be consulted for details of the
change.
No. : SP-1825
3.Action: From the start of 1994 September production.
2. Change in the length of the HL harness (margin up)
1.Model name: Z-20, 25, 27 (machines bound for areas using the 200 V series).
2.General: As a temporary measure for preventing the HL harness from coming in contact with the
heat sink, the wiring route of the harness was changed, but the length of the harness
line has been extended as a permanent measure, and the wiring route has been
changed back to the original route.
