SAFETY
GENERAL SAFETY RULES
!
DANGER
Never use the generator in a location
that is wet or damp. Never expose the
generator to rain, snow, water spray or
standing water while in use. Protect the
generator from all hazardous weather
conditions. Moisture or ice can cause a
short circuit or other malfunction in the
electrical circuit.
Never operate the generator in an
enclosed area. Engine exhaust
contains carbon monoxide. Only
operate the generator outside and away
from windows, doors and vents.
!
WARNING
Voltage produced by the generator
could result in death or serious injury.
• Never operate the generator in
rain or a floodplain unless proper
precautions are taken to avoid being
subject to rain or a flood.
• Never use worn or damaged
extension cords.
• Always have a licensed electrician
connect the generator to the utility
circuit.
• Never touch an operating generator
if the generator is wet or if you have
wet hands.
• Never operate the generator in highly
conductive areas such as around
metal decking or steel works.
• Always use grounded extension
cords. Always use three-wire or
double-insulated power tools.
• Never touch live terminals or
bare wires while the generator is
operating.
• Be sure the generator is properly
grounded before operating.
!
WARNING
Gasoline and gasoline vapors are
extremely flammable and explosive
under certain conditions.
• Always refuel the generator outdoors,
in a well-ventilated area.
• Never remove the fuel cap with the
engine running.
• Never refuel the generator while
the engine is running. Always turn
engine off and allow the generator to
cool before refueling.
• Only fill fuel tank with gasoline.
• Keep sparks, open flames or other
form of ignition (such as match,
cigarette, static electric source) away
when refueling.
• Never overfill the fuel tank. Leave
room for fuel to expand. Overfilling
the fuel tank can result in a sudden
overflow of gasoline and result in
spilled gasoline coming in contact
with HOT surfaces. Spilled fuel
can ignite. If fuel is spilled on
the generator, wipe up any spills
immediately. Dispose of rag properly.
Allow area of spilled fuel to dry
before operating the generator.
• Wear eye protection while refueling.
• Never use gasoline as a cleaning
agent.
• Store any containers containing
gasoline in a well-ventilated area,
away from any combustibles or
source of ignition.
• Check for fuel leaks after refueling.
Never operate the engine if a fuel leak
is discovered.

SAFETY
!
WARNING
Never operate the generator if powered
items overheat, electrical output drops,
there is sparking, flames or smoke
coming from the generator, or if the
receptacles are damaged.
!
Never use the generator to power
medical support equipment.
Always remove any tools or other
service equipment used during
maintenance from the generator before
operating.
NOTICE
Never modify the generator.
Never operate the generator if it vibrates at high
levels, if engine speed changes greatly or if the
engine misfires often.
Always disconnect tools or appliances from the
generator before starting.

ASSEMBLY
ASSEMBLY
Before assembling the generator,
review Safety on page 7 and the
following safety messages.
!
CAUTION
Never lift the generator without
assistance. The generator is heavy and
lifting without assistance could result
in personal injury.
!
Never use the handles as a lifting
point to support the entire weight of
the generator. Only use the handles
to move the generator by lifting the
handles and using the wheels to move
the generator.
Use caution when collapsing the
handles. Hands and fingers could get
caught and pinched.
NOTICE
Assembling the generator will require lifting the unit
on one side. Make sure all engine oil and fuel are
drained from the unit prior to assembling.
Once assembled, the wheel kit is not intended for
on-road use. The wheel kit is designed for use on this
generator only.
Tools required – tool bag (included).
1. Place generator on a flat surface.
2. Place a piece of cardboard or other soft material
to tip the generator onto, to protect the frame
paint and prevent the generator from sliding. Tip
the generator onto its side as shown in Figure 4
(engine should be on the bottom).

!
WARNING
To avoid electric shock:
• ALWAYS connect the positive (+)
battery cable (red boot) first when
connecting battery cables.
• ALWAYS disconnect the negative (-)
battery cable (black boot) first when
disconnecting battery cables.
• NEVER connect the negative (-)
battery cable (black boot) to the
positive (+) post on the battery.
• NEVER connect the positive (+)
battery cable (red boot) to the
negative (-) post on the battery.
• NEVER touch both battery posts
simultaneously.
• NEVER place a metal tool across
both battery posts.
• ALWAYS use insulated or non-
conducting tools when installing the
battery.
OTE:N The generator comes equipped with the
positive battery cable (red boot) already
attached.
1. Verify the positive (+) battery cable (red boot) is
securely tightened to the positive (+) battery post.
Make sure boot is over battery post.
2. Carefully remove the protective wrapping around
the lug of the negative (-) battery cable (black boot).
3. Locate negative (-) cable attached to alternator
cable, remove tie and route to the negative (-)
battery post.
4. Pull back the black boot and securely attach
the negative (-) battery cable (black boot) to the
negative (-) battery post as shown in Figure 8.
Replace the black boot so it protects the cable lug
and battery post.

OPERATION
BEFORE STARTING THE
GENERATOR
Before starting the generator, review
Safety on page 7.
Location Selection – Before starting the generator,
avoid exhaust and location hazards by verifying:
• You have selected a location to operate the
generator that is outdoors and well ventilated.
• You have selected a location with a level and solid
surface on which to place the generator.
• You have selected a location that is at least 6 feet
(1.8 m) away from any building, other equipment or
combustible material.
• If the generator is located close to a building, make
sure it is not located near any windows, doors
and/or vents.
!
WARNING
Always operate the generator on a level
surface. Placing the generator on non-
level surfaces can cause the generator
to tip over, causing fuel and oil to spill.
Spilled fuel can ignite if it comes in
contact with an ignition source such as
a very hot surface.
NOTICE
Only operate the generator on a solid, level surface.
Operating the generator on a surface with loose
material such as sand or grass clippings can cause
debris to be ingested by the generator that could:
• Block cooling vents
• Block air intake system
Weather – Never operate your generator outdoors
during rain, snow or any combination of weather
conditions that could lead to moisture collecting on, in
or around the generator.
Dry Surface – Always operate the generator on a dry
surface free of any moisture.
No Connected Loads – Make sure the generator
has no connected loads before starting it. To ensure
there are no connected loads, unplug any electrical
extension cords that are plugged into the control panel
receptacles.
NOTICE
Starting the generator with loads already applied
to it could result in damage to any appliance being
powered off the generator during the brief start-up
period.
Grounding the Generator – The National Electric
Code (NEC), as well as many local electrical codes,
require the generator to be connected to earth ground
before operating. Before starting the generator, make
sure it is connected to earth ground by connecting
the ground terminal on the control panel (see Figure
12) to earth ground using copper wire (minimum 10
AWG). Consult a qualified electrician for local grounding
requirements.
Figure 12 – Ground Terminal on the Control Panel

OPERATION
!
WARNING
Be sure the generator is properly
connected to earth ground before
operating. The generator must be
grounded to prevent electrical shock
due to faulty appliances.
