_,CAUTION!
,_ Never insert any object or tool through the air
cooling slots, even if the engine is not running.
NOTE:
DO NOTuse a gardenhoseto clean generator. Water can enter
the enginefuel systemand causeproblems,in addition,if water
enters the generatorthrough coolingair slots,some water will
be retainedin voidsand crevicesof the rotorand statorwinding
insulation. Water and dirt buildup on the generator internal
windingswill eventually decrease the insulationresistanceof
thesewindings.
3.4.2 TOCLEAN THEGENERATOR
• Use a damp cloth to wipe exteriorsurfaces clean.
• A soft, bristle brush may be usedto loosen caked on dirt, oil,
etc.
• A vacuumcleanermay be usedto pick up loose dirt and debris.
• Low pressure air (not to exceed 25 psi) may be used to
blow away dirt. Inspect cooling air slots and openings on the
generator. T heseopeningsmust be kept cleanandunobstructed.
