7.1 General
The electric system for this forklift truck is of the single-pole type，in which the
frame of the truck provides the return path for the electricity. The electric system
seems like “the nerve centre” of the truck.
For service and maintenance of Cummins QSB6.7 engine, please refer to the
documents supplied together with the machine and attention should be paid to the
following points for the entire truck:
(1) When the key is turned to the ON position, turn on the fault diagnosis switch.
