W0111A
Whenever carrying out a welding operation on the undercarriage or upperstructure carriage as authorized by the
manufacturer and in accordance with his instructions, disconnect the batteries, disconnect the alternator B+ and D+
terminal wires and connect the welding apparatus earth cable to the component on which the welding operation is
to be performed. Never connect the welding apparatus to the undercarriage when welding on the upperstructure (or
vice-versa). Never connect the welding apparatus earth to a component of the hydraulic system.
To avoid damage to the electronic/electrical systems, always observe the following:
1. Never make or break any of the charging circuit connections, including the battery connections, when the engine
is running.
2. Never short any of the charging components to ground.
3. Always place the key of the battery master switch in
“O”
(Off) position and disconnect the ground cable from the
battery before arc welding on the machine (if equipped).
• Position the welder ground clamp as close to the welding area as possible.
• If welding in close proximity to a computer module, then the module should be removed from the machine.
• Never allow welding cables to lay on, near or across any electrical wiring or electronic component while welding is
in progress.
4. Always disconnect the negative cable from the battery when charging the battery in the machine with a battery
charger.
ATTENTION:
If welding must be performed on the unit, either the machine, the battery ground cable must be discon-
nected from the machine battery. The electronic monitoring system and charging system will be damaged if this is
not done.
Remove the battery ground cable. Reconnect the cable when welding is completed.
