Fuel
..... N--N 22Nr
• Install fuel capand wipe up any spilled fuel.
IMPORTANT: It isimportantto prevent gum deposits
from forming in essentialfuel system parts,such asthe
carburetor, fuel filter, fuel hose or tank during storage.Also,
experience indicatesthat alcohol-blended fuels (called
gasohol,ethanol or methanol) can attract moisture, which
leadsto separation and formation of acids during storage.
Acidic fuel can damagethe fuel system of an enginewhile in
storage.
To avoid engine problems, the fuel system should be
emptied before storage of 30 claysor longer.See"Storage"
on page 13.NEVER use engine or carburetor cleaner
products in the fuel tank or permanent damagemay occur.

GROUNDING THE
G EN ERATO R
The National Electrical Code requires that the frame and
external electrically conductive parts of this generator be
properly connected to an approved earth ground. Local
electrical codes mayalso require proper grounding of the
unit. For that purpose, a GROUNDING WING NUT is
provided on the generator end (Figure 3).
Wing Nut
Generally,connecting a No. 12AWG (American Wire
Gauge) stranded copper wire to the grounding wing nut
and to an earth-driven copper or brass grounding rod
(electrode) provides adequate protection against electrical
shock. Be careful to keepthe grounding wire attached after
connecting the stranded copper wire. However, local codes
may vary widely.Consult with a localelectrician for
grounding requirements in your area.
Properly grounding the generator helps prevent electrical
shock if aground fault condition exists in the generator or
in connected electrical devices,especiallywhen the unit is
equipped with a wheel kit. Proper grounding also helps
dissipate static electricity, which often builds up in
ungrounded devices.
OPERATING THE
G EN ERATO R
A AUTION! Never start or stop the engine with
electrical loadsconnected to the receptaclesAND
with the connected devices turned ON.
Starting the Engine
Disconnect all electrical loadsfrom the generator. Use the

• Movethe fuel valveto the "Off' position.
Operating Automatic Idle Control
This switch isdesignedto greatly improve fuel economy.
When this switch is turned ON, the engine will only
run at its normal high governed engine speed when an
electrical load is connected.When an electrical load is
removed,the enginewill run at a reduced speed.With the
switch off, the enginewill run at the normal high engine
speed.Always have the switch off when starting and
stopping the engine.
Charging a Battery
_ ARNING! Storage batteries give off explosive
hydrogen gaswhile recharging.An explosive mixture
will remain around the battery for a long time after
it hasbeen charged.The slightest spark canignite
the hydrogen and causean explosion, resulting in
blindness or other serious injury.
_ ARNING! DO NOT permit smoking,open
flame,sparks or anyother source of heat around a
battery.Wear protective goggles,rubber apron and
rubber gloves when working around a battery.
Battery electrolyte fluidis an extremely caustic
sulfuric acid solution that can causesevere burns. If
spill occurs flush area with clear water immediately.
Your generator hasthe capability of recharging a discharged
12Volt automotive or utility style storage battery. DO
NOT use the unit to chargeany 6Volt batteries. DO NOT
usethe unit to crank an engine havinga discharged battery.
To recharge 12Volt batteries, proceed as follows:
• Check fluidlevel in all battery cells.If necessary,add
ONLY distilled water to cover separators in battery cells.
DO NOT use tap water.
• If the battery isequipped with vent caps,make sure they
are installed and are tight.
• If necessary,clean battery terminals.
• Connect battery charge cable connector plug to panel

Generator Maintenance
Generator maintenance consists of keeping the unit clean
and dry. Operate and store the unit in a dean dry
environment where it w{{{ 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.
NOTE: DO NOT use a garden hose to dean generator.
Water can enter engine fuel system and cause problems. In
addition, if water enters generator through cooling air slots,
some of the water wilt be retained in voids and cracks 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.
To Clean the Generator
_ii AUTION! NEVER insertany object or tool
through the air cooling slots, even ifthe engine is
not running.
• Use adamp cloth to wipe exterior surfaces clean.
• A soft bristle brush maybe used to loosen caked on dirt
or oil.
• A vacuum cleaner may be used to pick up loose dirt and
debris.
• Low pressure air (not to exceed 25 psi) may be used to
blow awaydirt. Inspectcooting air slots and opening on
generator.These openings must be kept clean and
unobstructed.
/
