Operation
System Ground
The generator is provided with a grounding fastener. The generator has a system
ground that connects the generator frame components to the ground terminals on the
AC output receptacles. The system ground is connected to the AC neutral wire (the
neutral is bonded to the generator frame).
Special Requirements
There may be Federal, local codes, or ordinances that apply to the intended use of the
generator. Please consult a qualified electrician, electrical inspector, or the local agency
having jurisdiction:
• In some areas, generators are required to be registered with local utility
companies.
• If the generator is used at a construction site, there may be additional
regulations which must be observed.
Connecting to a Building’s Electrical System
Connections for standby power to a building’s electrical system must use a listed
transfer switch installed by a current licensed electrician. The connection must isolate
the generator power from the utility power and must comply with all applicable laws
and electrical codes.

NOTICE This engine was shipped without oil. Before you start the engine, make sure
you add oil according to the instructions in this manual. If you start the engine without
oil, it will be damaged beyond repair and will not be covered under warranty.
NOTICE Before you start the engine, make sure that all electrical devices are
disconnected from the generator outlets.
1. Make sure unit is on a flat, level surface.
NOTICE Failure to start and operate the unit on a flat, level surface will cause the unit
not to start or shut down during operation.
2. Turn fuel valve ( L ) to on position (I).
3. Pull choke control ( S ) out to close choke ( ).
4A. For electric starting, turn and hold key in start switch ( T ) to start ( ) position
until generator starts. To prolong the life of starter components, DO NOT hold key
in start (
) position for more than 15 seconds, and pause for at least 1 minute
between starting attempts.
• If engine starts, proceed to step 6.
• If engine fails to start, proceed to step 5.
NOTICE If battery is discharged, use manual starting instructions.
4B. For manual starting, turn key in start switch to run ( I ) position, grasp recoil
handle ( M ) and pull slowly until slight resistance is felt. Then pull rapidly one
time only to start engine.
• If engine starts, proceed to step 6.
• If engine fails to start, proceed to step 5.
5. Push in the choke handle half way, turn key in start switch to run ( I ) position
and pull recoil handle twice or turn and hold key in start switch to start ( )
position as described in step 4A.
• If engine fails to start, repeat steps 3 thru 4.
6. Open the choke gradually as the engine warms up by pushing in on the choke
handle.
NOTICE If engine floods, push choke handle all the way in and crank until engine starts.
NOTICE If engine starts after 3 pulls but fails to run, or if unit shuts down during
operation, make sure unit is on a level surface and check for proper oil level in
crankcase. This unit is equipped with a low oil protection device. If so, oil must be at
proper level for engine to start.
WARNING Exhaust heat/gases could ignite combustibles, structures or
damage fuel tank causing a fire, resulting in death, serious
injury and/or property damage.
Contact with muffler area could cause burns resulting in
serious injury.
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 1.5 m (5 ft.) of clearance on all sides of generator including overhead.
• Contact the original equipment manufacturer, retailer, or dealer to obtain a
spark arrester designed for the exhaust system installed on this engine.
• Replacement parts must be the same and installed in the same position as
the original parts.

WARNING Starter cord kickback (rapid retraction) will pull hand and arm
toward engine faster than you can let go which could cause broken
bones, fractures, bruises, or sprains resulting in serious injury.
• When starting engine, pull cord slowly until resistance is felt and then pull rapidly
to avoid kickback.
• NEVER start or stop engine with electrical devices plugged in and turned on.
WARNING POISONOUS GAS HAZARD. Engine exhaust contains carbon
monoxide, a poisonous gas that could kill you in minutes. You CANNOT
see it, smell it, or taste it. Even if you do not smell exhaust fumes, you
could still be exposed to carbon monoxide gas. If you start to feel sick,
dizzy or weak while using this product, shut it off and get to fresh air
RIGHT AWAY. See a doctor. You may have carbon monoxide poisoning.
• Operate this product ONLY outside far away from windows, doors and vents to
reduce the risk of carbon monoxide gas from accumulating and potentially being
drawn towards occupied spaces.
• Install battery-operated carbon monoxide alarms or plug-in carbon monoxide
alarms with battery back-up according to the manufacturer’s instructions. Smoke
alarms cannot detect carbon monoxide gas.
• DO NOT run this product inside homes, garages, basements, crawlspaces,
sheds, or other partially-enclosed spaces even if using fans or opening doors and
windows for ventilation. Carbon monoxide can quickly build up in these spaces
and can linger for hours, even after the product has shut off.
• ALWAYS place this product downwind and point the engine exhaust away from
occupied spaces.
WARNING
Generator voltage could cause electrical shock or burn resulting
in death or serious injury.
• Use approved transfer equipment to prevent backfeed by isolating generator from
electric utility workers.
• When using generator for backup power, notify utility company.
• Use a residual-current device (RCD) in any damp or highly conductive area, such
as metal decking or steel work.
• DO NOT touch bare wires or receptacles.
• DO NOT use generator with electrical cords which are worn, frayed, bare or
otherwise damaged.
• DO NOT operate generator in the rain or wet weather.
• DO NOT handle generator or electrical cords while standing in water, while
barefoot, or while hands or feet are wet.
• DO NOT allow unqualified persons or children to operate or service generator.
