GENERATOR/WELDER MAINTENANCE

STORAGE: Store the POWER-ARC 4000 in clean,
dry, protected areas.
CLEANING: Blow out the generator and controls
periodically with low pressure air. Do this at least
once a week in particularly dirty areas.
BRUSH REMOVAL AND REPLACEMENT: See
Figure D.5. It's normal for the brushes and slip rings
to wear and darken slightly. Inspect the brushes
when a generator overhaul is necessary. Remove
the brushes and clean the slip rings with fine grit
sandpaper. To reinstall the brushes, press them
upward and slide a cable tie or wooden stick
