GENERATOR CARE
Proper care and maintenance of the generator is necessary to ensure a
long trouble free life.
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 ensure that the set is operating properly
should it be needed in an emergency.
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. The 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 ensure 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 fly wheel. 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.
1. Unsnap the air cleaner cover clips,
remove the air cleaner cover and
remove the air filter element.
2. Wash the element in a solution of
household detergent and warm
water, then rinse thoroughly. Or
wash in a non-flammable or high
flash point solvent. Allow the element
to dry thoroughly.
3. Soak the air filter element in clean engine oil and squeeze the
excess oil. he engine will smoke during the initial start up if too
much oil is left in the element.
4. Reinstall the air filter element and the cover.
SEDIMENT CUP
DANGER: PERSONAL INJURY
Gasoline is highly flammable and explosive, and you can be burned or
seriously injured when handling fuel.
1. Remove the fuel valve to the OFF position, then remove the fuel
sediment cup and O-Ring.
2. Wash the sediment cup in non-flammable solvent, and dry
thoroughly.
3. Place the O-Ring in the fuel valve and install the sediment cup.
Tighten the sediment cup securely.
4. Move the fuel valve to the ON position, and check for leaks.
Replace the O-Ring if there is any leakage.
SPARK PLUG
Replace annually or every 300 hours of operation. Always replace with
the same spark plug that came in the engine and check gap before
installing. Spark plug gap is 0.030”. Poor spark will also occur if spark
plug wire does not fit firmly on spark plug. If this happens, reform the
terminal to fit firmly on spark plug tip.
CARBON CANISTER
Designed to collect, store, and dispose of fuel vapors created in the
fuel tank/fuel system. The canister should last the life of the unit as long
as it stays dry.
