Starting relay

Assistant start button

The assistant start button is located at the right side of cab rear support. When the engine need to be repaired

under the truck, put the ignition switch to "ON" position and make the ignition relay's contactor pull-in. Let the
transmission in idle position and join up the idle switch. Press the sub-starting button under the truck to start the

Electromagnetic Main Power Switch

Operation principle

When this switch is turned on, the current passes through the coil and the contactor closed to connect the bat-

tery cathode and chassis frame.

As soon as fuse is burnt the electromagnetic main supply switch will automatically cut off the battery nega-

tive earthed circuit. So there will be no electricity in the complete truck.
