SAFETY
GENERAL SAFETY RULES
!DANGER
Never use the inverter in a location
that is wet or damp. Never expose the
inverter to rain, snow, water spray or
standing water while in use. Protect
the inverter from all hazardous weather
conditions. Moisture or ice can cause a
short circuit or other malfunction in the
electrical circuit.
Never operate the inverter in an
enclosed area. Engine exhaust
contains carbon monoxide. Only
operate the inverter outside and away
from windows, doors and vents.
!WARNING
Voltage produced by the inverter could
result in death or serious injury.
• Never operate the inverter 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 inverter to the utility
circuit.
• Never touch an operating inverter if
the inverter is wet or if you have wet
hands.
• Never operate the inverter 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 inverter is operating.
• Be sure the inverter is properly
grounded before operating.
!WARNING
Gasoline and gasoline vapors are
extremely flammable and explosive
under certain conditions.
• Always refuel the inverter outdoors,
in a well-ventilated area.
• Never remove the fuel cap with the
engine running.
• Never refuel the inverter while the
engine is running. Always turn
engine off and allow the inverter 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 inverter,
wipe up any spills immediately.
Dispose of rag properly. Allow area
of spilled fuel to dry before operating
the inverter.
• 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 inverter if powered
items overheat, electrical output drops,
there is sparking, flames or smoke
coming from the inverter, or if the
receptacles are damaged.
!Never use the inverter to power
medical support equipment.
Always remove any tools or other
service equipment used during
maintenance from the inverter before
operating.
NOTICE
Never modify the inverter.
Never operate the inverter if it vibrates at high levels,
if engine speed changes greatly or if the engine
misfires often.
Always disconnect tools or appliances from the
inverter before starting.

OPERATION
BEFORE STARTING THE
INVERTER
Before starting the inverter, review
Safety on page 7.
Location Selection – Before starting the inverter, avoid
exhaust and location hazards by verifying:
x You have selected a location to operate the inverter
that is outdoors and well ventilated.
x You have selected a location with a level and solid
surface on which to place the inverter.
x You have selected a location that is at least 6 feet
(1.8 m) away from any building, other equipment or
combustible material.
x If the inverter is located close to a building, make
sure it is not located near any windows, doors
and/or vents.
!WARNING
Always operate the inverter on a level
surface. Placing the inverter on non-
level surfaces can cause the inverter
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 inverter on a solid, level surface.
Operating the inverter on a surface with loose
material such as sand or grass clippings can cause
debris to be ingested by the inverter that could:
• Block cooling vents
• Block air intake system
Weather – Never operate your inverter outdoors during
rain, snow or any combination of weather conditions
that could lead to moisture collecting on, in or around
the inverter.
Dry Surface – Always operate the inverter on a dry
surface free of any moisture.
No Connected Loads – Make sure the inverter
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 inverter with loads already applied to
it could result in damage to any appliance being
powered off the inverter during the brief start-up
period.
Grounding the Inverter – The National Electric Code
(NEC), as well as many local electrical codes, require
the inverter to be connected to earth ground before
operating. Before starting the inverter, make sure it is
connected to earth ground by connecting the ground
terminal on the control panel (see Figure 9) to earth
ground using copper wire (minimum 10 AWG). Consult
a qualified electrician for local grounding requirements.
Figure 9 – Ground Terminal on the Control Panel
!WARNING
Be sure the inverter is properly
connected to earth ground before
operating.The inverter must be
grounded to prevent electrical shock
due to faulty appliances.
