CHAPTER 8 – ELECTRICAL SYSTEM
Precautions To Be Taken Before Performing Any Welding Procedure on the Machine
845B and 865B with ZF Transmission Before performing any welding work on the machine, turn off the ignition switch, making sure to place it to the “OFF” position. Connect the ground cable of the welding equipment to a maximum distance of 0,6 m (2 ft) from the part being welded. For a safe welding procedure performance, some electronic component connectors must be disconnected. Make sure to disconnect the connectors listed below.
Front panel – Disconnect the 70-pin X6 connector (4) from the front panel, located on the right hand-side of the rear chassis, between the cabin mounting brackets. To disconnect, loosen the center screw on the connector using a 4 mm Allen wrench.
