DUAL ELEMENT AIR FILTER
Clean and/or replace the foam pre-cleaner and the air filter annually or
every 100 hours. Service more often under dusty conditions.
WARNING: EQUIPMENT DAMAGE
Never start or run the engine with the air filter removed.
A. Loosen snaps (A) and
remove cover (B).
B. Remove the nut (D) and the
retainer
(E).
C. Remove the air filter (F).
D. Remove the pre-cleaner (G)
from the air filter.
E. To loosen debris, gently tap the
air filter on a hard surface. If the
air filter is excessively dirty
replace with a new filter.
You can use pressurized air
(not to exceed 30 psi)
to clean the filter. Always blow the compressed air from inside to
the
outside.
F. Wash the pre-cleaner in liquid detergent and water. Then allow it
to thoroughly air dry. DO NOT oil the pre-cleaner.

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.

ENGINE CARE
If major engine service or repair is required, contact
an authorized engine service center. The manufac-
turer of these engines has established an excellent
world-wide engine service organization. Engine ser-
vice is very likely available from a nearby authorized
dealer or distributor. Check the yellow pages of your
local telephone directory under “Engines-Gasoline”
for the closest engine repair center or ask the dealer
from whom you purchased the power plant.
1.
Change the oil
after the
fi
rst 5 hours of operation
and yearly or 100 hours thereafter under normal op-
erating conditions. Change engine oil every 50 hours
of operation if the engine is operated under heavy
load, or in high ambient temperatures.
a. Start the engine and warm it up, stop the engine
and remove the spark plug wire to prevent it
from accidently being started.
b. Remove oil drain plug at base of the engine
(Ref “B”) and drain the oil into an approved
container.
c. Remove the oil
fi
lter (Ref “C”) and dispose of it
properly.
d. Before you install the new oil
fi
lter, lightly lubri-
cate the oil
fi
lter gasket with fresh clean oil.
e. Install the oil
fi
lter by hand until the gasket
contacts the oil
fi
lter adapter, then tighten the oil
fi
lter 1/2 to 3/4 turns.
f. Replace oil drain plug.
g. Remove oil
fi
ller plug and re
fi
ll with new oil.
Refer to the table on page 5 for the proper
grade of oil based on your operating
temperature.
NOTE: This engine requires 78 to 80 ounces of oil
if it is completely drained. Use caution when re
fi
lling
the engine as some residual oil may have remained
in the engine. Always use the dipstick when
fi
lling
the engine with oil to prevent over
fi
lling.
h. Replace
fi
ller plug.
I. Start the engine and warm it up.
J. After warming up the engine, recheck the oil
level and re
fi
ll as necessary to bring it to the
proper level. See page 5 for proper oil level.

Checking the Oil Level
: The oil level must al-
ways be checked before the engine is started. Take
care to remove any dirt or debris from around the
oil
fi
ll plug before removing. Be sure the oil level is
maintained. Fill to the “
FULL
” mark on the dipstick.
3.
Dual Element Air Filter
: Clean and/or replace
foam pre-cleaner and air
fi
lter annually or every 100
hours. Service more often under dusty conditions.

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.
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.
