Welding Precautions
When welding, the following must be done to avoid damage to the machine electrical
systems.
1. Turn the night switch to the OFF position as per
the Night Switch procedure in this manual.
2. Both the positive (+) and the negative (-) battery leads must be disconnected
before welding.
3. Unplug the following four computer harnesses, located in the cab riser prior to

near electrode so that no current will flow through bearings, bushings or pinned
connections.
