Precautions for electric welding
Inadvertent electric welding on a cab or frame may cause reverse welding current from the grounding
circuit, resulting in damage to electric and electronic parts. Observe the following items for electric
welding.
(1)
Turn "OFF" the starter switch.
(2)
Make sure that switches are "OFF".
(3)
Disconnect the minus (-) terminal of the battery according to the removal procedure of the battery cable.
(4)
Disconnect connectors of each computer.
(5)
Remove all fuses. (For locations of fuses, refer to "Electrical Chapter".)
(6)
Be sure to connect grounding of the electric welding machine near the welding area.
Connect grounding from a bolt (plated bolt) or a frame near the welding area.
Remove paint of the frame for connection of grounding from the frame.
(7)
Other precautions
a.
Put a cover on rubber hoses, wire harnesses, pipes, tires, etc. around the welding area so that they
may not be exposed to spatter.
b.
Perform welding under appropriate conditions and minimize heat effect in the peripheral area. Also
maintain welding quality.
(8)
After welding, connect and assemble in the order of the fuse and the minus terminal of the battery
disassembled. When paint is removed from a frame or cab, apply rust preventive coating with the same
color.
(9)
After reassembly, check the function if it operates correctly.
