SECTION 4 — PREPARATION BEFORE OPERATION
4.1 ADDING ENGINE OIL
Please add properly oil before starting the
generator.Use nonspecial additives. Select
the oil’s Viscosity grade according to the
expected operating temperature (also see
chart).
•Use regular UNLEADED gasoline with the
generator engine. Do not use any fuel with more
than 10% added ethanol, and never use E85 fuel.
•Do not mix oil with gasoline.
•Install fuel cap and wipe up any spilled
gasoline.
Above 40 F, use SAE 30
Below 40 F and down to 10 F, use 10W-30 CAUTION Do not overfill the fuel tank.
Below, 10 F use synthetic 5W-30
Allow space for fuel expansion.
IF the fuel tank is overfilled, fuel
can overflow onto a HOT engine and cause FIRE or
EXPLOSION. If fuel spills, wait until it
evaporates
before starting engine. Check fuel
lines, tank, cap and
fittings frequently for cracks
or leaks. Replace if
necessary.
NOTICE Improper treatment of generator could
damage it and shorten its life. DO NOT attempt crank
or start the engine before it has been properly serviced
with the recommended oil. This could result in an
engine failure.
•Place generator on a flat, level surface.
•Clean area around oil fill and remove oil fill cap /
dipstick. Wipe dipstick clean.
•Slowly fill engine with oil through the oil fill
opening until it reaches the full mark on the
dipstick. Stop filling occasionally to check oil level.
Be careful do not over fill.
•Install oil fill cap and finger tighten securely
•Check engine oil level before starting each time
thereafter.
4.2 ADDING FUEL
DANGER Never fill tank indoors. Never fill
fuel
tank when engine is running
or hot.
Turn generator engine
OFF and allow engine to cool entirely before filling fuel
tank. Avoid spilling gasoline on HOT engine. Keep fuel
away from sparks, open flames, pilot lights, heat, and
other ignition sources. DO NOT light a cigarette or
smoke when filling the
fuel tank. Fuel is highly
FLAMMABLE, and its vapors are EXPLOSIVE.
IMPORTANT: It is important to prevent gum
deposits from forming in fuel system parts such
as the carburetor, fuel hose or tank during storage.
Alcohol-blended fuels (called gasohol), ethanol
or
methanol) can attract moisture, which leads to
separation and formation of acids during storage.
Acidic gas can damage the fuel system. The fuel
should
be emptied before storage of 30 days or longer. See the
“Storage” section. Never use engine or carburetor
cleaner products in the fuel tank as permanent damage
may occur.
4.3 GROUNDING THE GENERATOR

IMPORTANT Do not overload the generator.
Also, do not overload individual panel
receptacles. These outlets are protected against
overload with push-to-reset-type circuit breakers.
If amperage rating of any circuit breaker is
exceeded, that breaker opens and electrical
output
to that receptacle is lost.
5.2 CONNECTING ELECTRICAL
LOADS
•Let engine runs stable and warm up for a
few minutes after starting.
•Plug in and turn on the electrical loads.
•Add up the rated watts (or amps) of all loads
to be connected at one time. This total should
not be
greater than (a) the rated
wattage/amperage
capacity of the generator or
(b) circuit breaker
rating of the receptacle
supplying the power.
NOTICE Start generator and let engine
stabilize before connecting electrical loads.
Connect electrical loads in OFF position then turn
ON for operation.
Turn electrical loads OFF and disconnect from
generator before stopping generator.
NOTICE Exceeding generators wattage/
amperage capacity could damage generator
and/or electrical devices connected to it. DO
NOT exceed the generator’s
wattage/amperage
capacity.
•Overloading a generator in excess of it
rated
wattage capacity can result in damage
to the
damage to the generator and to
connected
electrical devices. Observe the
following to
prevent overloading the unit:
•Add up the total wattage of all electrical devices
to be connected at one time. This total should
NOT be greater than the generator’s wattage
capacity.
The rated wattage of lights can be taken from
light bulbs. The rated wattage of tools,
appliances
and motors can usually be found on
a data label
or decal affixed to be the device.
If the appliance, tool or motor does not give
wattage, multiply volts times ampere rating to
determine watts (volts× amps = watts).
Some electric motors, such as induction types,
require about three times more watts of power
for starting than for running. This surge of
power lasts only a few seconds when starting
such motors. Make sure to allow for high
starting
wattage when selecting electrical
devices to connect to the generator:
•Figure the watts needed to start the
largest
motor.
•Add to that figure the running watts of all
other
connected loads.
The wattage reference guide is provided to assist
in determining how many items the generator
can operate at one time.
5.3 STOPPING THE ENGINE
Shut off all loads then unplug the electrical loads
from generator panel receptacles. Never start or
stop the engine with electrical devices plugged in
and turned on.
Let engine run at no-load for several minutes
to
stabilize the internal temperatures of engine
and generator.
Move ON/OFF switch to OFF position. Close
fuel valve.
5.4 LOW OIL LEVEL SHUTDOWN
SYSTEM
The engine is equipped with a low oil level
sensor that shuts down the engine automatically
when the oil level drops below a specified level.
If the engine shuts down by itself and the fuel
tank has enough gasoline, check engine oil
level.
5.5 HIGH ALTITUDE
At altitudes over 5,000 feet (1524 meters), a
minimum 85 octane / 85 (89 RON) gasoline is
acceptable. To remain emissions compliant, high
altitude adjustment is required. Operation
without
this adjustment will cause decreased
performance, increased fuel consumption, and
increased emissions. See an authorized dealer
for high altitude adjustment information.
Operation
of the engine at altitudes below 2,500
feet (762 meters) with the high-altitude kit is not
recommended.

SECTION 6 — MAINTENANCE
6.1 MAINTENANCE SCHEDULE
Follow the calendar intervals shown below.
More frequent service is required when
operating in adverse conditions.
6.2.1 GENERATOR MAINTENANCE
Generator maintenance consists of keeping the
unit clean and dry. Operate and store the unit in
a
clean dry environment where it will not be
exposed to excessive dust, dirt, moisture or any
corrosive vapors. Cooling air slots in the
generator must not become clogged with snow,
leaves, or any other foreign material.
Check the cleanliness of the generator frequently
and clean when dust, dirt, oil, moisture or other
foreign substances are visible on its exterior
surface.
CAUTION Never insert any object or tool
though the air cooling slots, even if the engine
is
not running.
6.2 GENERAL RECOMMENDATIONS
The warranty of the generator does not cover
items that have been subjected to operator
abuse
or negligence. To receive full value from
the
warranty, the operator must maintain the
generator as instructed in this manual.
Some adjustments will need to be made
periodically to properly maintain the generator.
All adjustments in the Maintenance section of
this manual should be made at least once each
season. Follow the requirements in the
“Maintenance Schedule”.
NOTE Once a year replace the spark plug
and replace the air filter. A new spark plug and
clean air filter assure proper fuel-air mixture and
help the engine run better and last longer.
NOTE DO NOT use a garden hose to clean
generator. Water can enter the engine fuel
system
and cause problems. In addition, if water
enters
the generator though cooling air slots,
some water
will be retained in voids and crevices
of the rotor and stator winding insulation. Water
and dirt
buildup on the generator internal
windings will
eventually decrease the insulation
resistance of these windings.
6.2.2 TO CLEAN THE GENERATOR
•Use a damp cloth to wipe exterior surfaces
clean.
•A soft, bristle brush may be used to
loosen
caked on dirt, oil etc.
•A vacuum cleaner may be used to pick up loose

6.4 VALVE CLEARANCE
After the first 50 hours of operation, check the
valve clearance in the engine and adjust
if
necessary.
Important: If feeling uncomfortable about doing
this procedure or the proper tools are not
available, please take the generator to the
nearest
service center to have the valve
clearance
adjusted. This is a very important step
to ensure
longest life for the engine.
6.5 GENERAL
The generator should be started at least once
every seven days and be allowed to run at least
30 minutes. If this cannot be done and the unit
must
be stored for more than 30 days, use the
following
information as a guide to prepare it for
storage.
DANGER NEVER store engine with fuel in
tank indoors or in enclosed, poorly ventilated
areas where fumes may reach an open flame,
spark or pilot light as on a furnace, water heater,
clothes dryer or other gas appliance.
SECTION 7 — STORAGE
It is important to avoid gum deposits from forming
in essential fuel system parts such as the
carburetor,
fuel hose or tank during storage. Also,
experience
indicates that alcohol-blended fuels
(called gasohol, ethanol or methanol) can attract
moisture, which leads to separation and formation
of acids storage. Acidic gas can damage the fuel
system of an engine while in storage.
To avoid engine problems, the fuel system should
be emptied before storage of 30 days or longer,
as follows:
•Remove all gasoline from the fuel tank.
•Start and run engine until engine stops
from
lack of fuel.
•While engine is still warm, drain oil from
crankcase. Refill with recommended grade.
•Remove spark plugs and pour about 1/2 ounce
(15 ml) of engine oil the cylinders. Cover the
spark plug hole with rag. Pull the recoil starter a
couple
