INTRODUCTION
PROTECTING THE ELECTRONIC/ELECTRICAL SYSTEMS DURING CHARGING OR WELD-
ING
To avoid damage to the electronic/electrical systems, always observe the following:
1. Never connect or disconnect any part of the charging circuit, including the battery connections, when the engine
is running.
2. Never short any of the charging components to earth.
3. Always disconnect the ground cable from the battery before arc welding on the combine or on any header attached
to the combine.
• 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 combine
• 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 combine with a battery
charger.
NOTICE:
If welding must be performed on the unit, either the combine or the header (if it is attached), the battery
ground cable must be disconnected from the combine 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.
ATTENTION:
Battery acid causes severe burns. Batteries contain sulfuric acid. Avoid contact with skin, eyes, and
clothing. Antidote - EXTERNAL: flush with water. INTERNAL: Drink large quantities of water or milk. Follow with milk
of magnesia, beaten egg or vegetable oil. Call a doctor immediately. EYES: Flush with water for 15 minutes and seek
immediate medical attention.
