OPERATOR CARE AND MAINTENANCE
5. Spark Plug - Clean and reset gap at .030" every 100
hours of operation. Do not blast clean spark plug. Clean by
scraping or wire brushing and washing with a commercial
solvent. Poor spark will occur if terminal does not fit firmly on
spark plug. If this happens reform the terminal to fit firmly on
spark plug tip.
GENERATOR CARE
Proper care and maintenance of the generator is
necessary to insure a long trouble free life.
1. Exercising The Generator - The generator should be
operated every three to four weeks. It should be
operated for a period of time sufficient to warm the
unit up and to dry out any moisture that has
accumulated in the windings. If left, this moisture can
cause corrosion in the winding. Frequent operation of
the engine generator set will also insure that the set
is operating properly should it be needed in an
emergency.
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.
