2. Generator Maintenance - Any major generator
service, including the installation or replacement
of parts, should be performed only by a qualified
electrical service technician. USE ONLY FACTORY
APPROVED REPAIR PARTS.
a. Bearing - The bearing used in these generators
is a heavy duty double sealed ball bearing.
They require no maintenance or lubrication.
b. Receptacles - Quality receptacles have been
utilized. If a receptacle should become cracked
or otherwise damaged, replace it. Using dam-
aged or cracked receptacles can be both dan-
gerous to the operator and destructive to the
equipment.
CLEANING
Remove dirt and debris with a cloth or brush. DO
NOT use high pressure spray to clean either the
engine or the generator. This high pressure spray
could contaminate the fuel system and the genera-
tor components.
1. Keep the air inlet screen on both the engine and
generator free of any dirt or debris to insure proper
cooling. At least yearly, remove the blower housing
on the engine and clean the chaff and dirt out of the
engine cooling fins and flywheel. Clean more often
if necessary. Failure to keep these areas clean may
cause overheating and permanent damage to the
unit.
2. Periodically clean muffler area to remove all
grass, dirt and combustible debris to prevent a fire.
3. On engine mufflers equipped with spark arrest-
ers, the spark arrester must be removed every 50
hours for cleaning and inspection. Replace if dam-
aged
