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 damaged or cracked
receptacles can be both dangerous 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 generator 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 arresters, the
spark arrester must be removed every 50 hours for
cleaning and inspection. Replace if damaged.
