GENERATOR/WELDER MAINTENANCE

STORAGE: Store the POWER-ARC 5500 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 R EMOVAL AND R EPLACEMENT: See Figure D.5. 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.

NOTE: Lincoln offers a rotor removal kit for any ser- vice which requires removal of the rotor from the engine. See the ACCESSORIES section for further details.

Removal of engine/generator assembly from the cradle can be achieved as follows:

•Remove the two 5/16-18 hex head cap screws from the engine block via the access hole located in the cradle cross support channel. Leave all other engine mountings intact.

•Remove the two hex nuts from the isolator thread- ed posts at the stator support bracket located opposite the engine. Leave all other stator mount- ings intact.

•With a jib hoist or crane, lift the unit upward and remove loose cradle from engine/generator assembly.
