INTRODUCTION
Protecting the electronic and/or electrical systems during charging and welding
To avoid damage to the electronic and/or electrical systems, always observe the following practices:
1. Never make or break any of the charging circuit connections when the engine is running, including the battery
connections.
2. Never short any of the charging components to ground.
3. Always disconnect the ground cable from the battery before arc welding on the machine or on any machine
attachment.
• Position the welder ground clamp as close to the welding area as possible.
• If you weld in close proximity to a computer module, then you should remove the module from the machine.
• Never allow welding cables to lie on, near, or across any electrical wiring or electronic component while you
weld.
4. Always disconnect the negative cable from the battery when charging the battery in the machine with a battery
charger.
NOTICE: If you must weld on the unit, you must disconnect the battery ground cable from the machine battery.
The electronic monitoring system and charging system will be damaged if this is not done.
5. Remove the battery ground cable. Reconnect the cable when you complete welding.
