OPERATOR CARE AND MAINTENANCE
2. Checking the Oil Level: The oil level must always be
checked before the engine is started. Take care to remove
any dirt or debris from around the oil fill plug before
removing. Be sure the oil level is maintained. FILL TO
POINT OF OVERFLOWING or on units with the extended oil
fill to the “FULL” mark on the dipstick.
3. Cartridge Air Cleaner - Remove and clean cartridge
yearly or after every 25 hours, whichever occurs first. Service
more often if necessary. Clean by tapping gently on flat
surface. If very dirty, replace the cartridge using only original
equipment parts available at any engine service center.
Do not use petroleum solvents, such as kerosene, to
attempt to clean the cartridge. They may cause deterioration
of the cartridge. DO NOT OIL CARTRIDGE, DO NOT USE
PRESSURIZED AIR TO CLEAN OR DRY CARTRIDGE.
4. Dual Element Air Cleaner - Clean and re-oil foam pre-
cleaner at three month intervals or every 25 hours, whichever
occurs first. Service more often under dusty conditions.
a. Remove knob and cover.
b. Remove foam pre-cleaner by sliding it off the paper
cartridge.
c. Wash foam pre-cleaner in kerosene or liquid
detergent and water
d. Wrap foam pre-cleaner in cloth and squeeze dry.
e. Saturate foam pre-cleaner in engine oil. Squeeze
to remove excess oil.
f. Install foam pre-cleaner over paper cartridge.
Reassemble cover and screw down tight.
Replace the cartridge included with Dual Element Air
Cleaner yearly or every 100 hours. Service more often if
necessary.
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.
