GENERATOR/WELDER MAINTENANCE
STORAGE: Store the POWER ARC 5000 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.6. It's normal for the brushes and slip
rings to wear and darken slightly. Inspect the
brushes when a general overhaul is necessary.
Remove the brushes and clean the slip rings with
fine grit emery paper.
CAUTION
Do not attempt to polish slip rings while engine is
running.

To reinstall the brushes, press them upward and
slide a cable tie or wooden stick through the brush
holder tabs. Install the brush holder into the bear-
ing end bracket and secure with the screws previ-
ously removed. Remove the cable tie or wooden
stick and the brushes will seat onto the slip rings.
RECEPTACLES: Keep the electrical receptacles in
good condition. Remove any dirt, oil, or other
debris from their surfaces and holes.
CABLE CONNECTIONS: Check the welding cable
connections at the weld output terminals often. Be
sure that the connections are always tight.
