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 – SERIAL NUMBER
XXXXXX0612 AND EARLIER
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 5
(engine should be on the bottom).
Figure 5 – Tip the Generator onto its Side
3. Install the rubber pads to the feet using the two
M6 x 18 flange bolts (see Figure 6).

INSTALLING THE BATTERY
(ELECTRIC START
GENERATORS ONLY)
!WARNING
To avoid electric shock:
• ALWAYS connect the positive (+)
battery wire (red boot) first when
connecting battery wires.
• ALWAYS disconnect the negative (-)
battery wire (black boot) first when
disconnecting battery wires.
• NEVER connect the negative (-)
battery wire (black boot) to the
positive (+) post on the battery.
• NEVER connect the positive (+)
battery wire (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 wire (red boot) already
attached.
1. Verify the positive (+) battery wire (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 wire (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 wire (black boot) to the negative
(-) battery post as shown in Figure 15. Replace the
black boot so it protects the wire lug and battery
post.
