DO NOT attempt to crank or start the engine
before it has been properly filled with the
recommended type and amount of oil. Damage
to the generator as a result of failure to follow
these instructions will void your warranty.
1.Place generator on a flat and level surface.
2.Loosen the cover screw and remove the
maintenance cover.
NOTE:
The recommended oil type is 10W-30 automotive
oil. However outdoor temperatures will determine
the space proper oil viscosity for the engine. Use the
chart to select the best for the outdoor temperature
range expected.
The engine is equipped with a low oil shut-off and
will stop when the oil level in the crankcase falls
below the threshold level.
NOTE:
We consider the first 5 hours of run time to be
the break-in period for the unit. During the break
in period stay at or below 50% of the running
watt rating and vary the load occasionally to allow
stator windings to heat and cool. Adjusting the
load will also cause engine speed to vary and help
seat piston rings.
CAUTION
The unit is equipped with a low oil shutdown.If
the oil level becomes lower than required,the
sensor will activate a warning device or stop the
engine.
If generator shuts off and the oil level is within
specifications, check to see if generator is sitting
at an angle that forces oil to shift. Place on an
even surface to correct this. If engine fails to
start, the oil level may not be sufficient to
deactivate low oil level switch. Make sure the
sump is completely full of oil.
5.Replace oil fill cap/dipstick and fully tighten.
6.Reinstall maintenance cover and tighten screws.
4.Using oil funnel, slowly pour contents of
provided oil bottle into oil fill opening to the
"H" mark on dipstick. Be careful do not
overfill. Overfilling with oil could cause the
engine to not start or hard starting.

Add Fuel
Page 12
Fuel must meet these requirements:
•Clean, fresh, unleaded gasoline.
Use regular UNLEADED gasoline with the
generator engine with a minimum 87 octane
/ 87 AKI (91 RON).
For high altitude use, see "Operation at High
Altitude".
Do not use gasoline with more than 10%
alcohol such as E85 or ethanol.
•
•
Failure to follow Operator's Manual for fuel
recommendations voids warranty.
Avoid generator damage.
DO NOT use unapproved gasoline such as E85.
DO NOT mix oil in gasoline.
DO NOT modify engine to run on alternate fuels.
•
•
•
WARNING
Fuel and its vapors are extremely flammable
and explosive which could cause burns, fire or
explosion resulting in death, serious injury
and/or property damage.
WHEN ADDING FUEL
Fill fuel tank outdoors.
DO NOT overfill tank. Allow space for fuel
expansion. If the tank is overfilled, fuel
can overflow onto a hot engine and cause fire
or explosion. Wipe up any spilled fuel
immediately.
If fuel spills, wait until it evaporates before
starting engine.
Keep fuel away from sparks, open flames,
pilot lights, heat, and other ignition sources.
Check fuel lines, tank, cap and fittings
frequently for cracks or leaks. Replace if
necessary.
DO NOT light a cigarette or smoke when
filling the fuel tank.
•
•
•
•
1.Clean area around fuel fill cap, remove cap.
2.Slowly add unleaded fuel to fuel tank. Be
careful not to fill above the red fuel level
indicator . This allows adequate space for
fuel expansion.
3.Install fuel cap and let any spilled fuel
evaporate before starting engine or wipe up
any spilled gasoline.
CAUTION
Slowly add unleaded gasoline to fuel tank.
Do not overfill tank.

English Customer Service: 1-844-FIRMAN1
Do not fill above the red fuel level indicator.
This will allow expansion in hot weather and
prevent overflow.
Red Fuel Level Indicator
Operation at High Altitude
At altitudes over 5,000 feet(1524 meters), a
minimum 85 octane / 85 AKI (89 RON) gasoline
is acceptable.
The density of air at high altitude is lower than at
sea level. Engine power is reduced as the air mass
and air-fuel ratio decrease. Engine power and
generator output will be reduced approximately
3.5% for every 1000 feet of elevation above sea level.
This is a natural trend and cannot be changed by
IMPORTANT: It is important to prevent gum
deposits from forming in fuel system parts such
as the carburetor, fuel hose or tank during
storage. Alcohol-blended fuels (called gasohol,
ethanol or methanol) can attract moisture, which
leads to separation and formation of acids during
storage. Acidic gas can damage the fuel system
of an engine while in storage. To avoid engine
problems, the fuel system should be emptied
before storage of 30 days or longer. See the
" Long Term Storage" section. Never use engine
or carburetor cleaner products in the fuel tank
as permanent damage may occur.

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 ground fault circuit interrupter (GFCI) 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

Connecting Electrical Loads
1.Let engine stabilize and warm up for a few
minutes after starting.
2.Ensure circuit breaker on control panel is in
on position.
This unit has been pretested and adjusted to
handle its full capacity. Before starting the
generator, disconnect all load. Apply load only
after generator is running. Voltage is regulated
via the engine speed adjusted at the factory for
correct output. Readjusting will void warranty.
CAUTION
When applying a load, do not exceed the maximum
wattage rating of the generator when using one or
more receptacles. Also, do not exceed the amperage
rating of any one receptacle.
Do not apply heavy electrical load during break-in
period (the first five hours of operations).
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 may be equipped
with a low oil protection device. If so, oil must
be at proper level for engine to start.
Keep choke lever in “CHOKE” position for only 1
pull of the recoil starter. After first pull, move
choke lever to the “RUN” position for up to the
next 3 pulls of the recoil starter. Too much
choke leads to sparkplug fouling/engine
flooding due to the lack of incoming air. This
will cause the engine not to start.
3.Plug in and turn on the desired 120 Volt AC,
single phase, 60Hz electrical loads. It is
better to attach the item with largest load first.
electrical system, consult your local utility
company or a qualified electrician. Connections
must isolate generator power from utility
power and must comply with all applicable laws
and codes.
Connecting a generator to your electric utility
company’s power lines or to another power
source may be against the law. In addition this
action, if done incorrectly, could damage your
generator and appliances and could cause
serious injury or even death to you or a utility
worker who may be working on nearby power
lines. If you plan to run a portable electric
generator during an outage, please notify your
electric utility company immediately and
remember to plug your appliances directly into
the generator. Do not plug the generator into
any electric outlet in your home. Doing so could
create a connection to the utility company
power lines. You are responsible for ensuring
that your generator’s electricity does not feed
back into the electric utility power lines.
If the generator will be connected to a building
Economy Control Switch
The Economy Control switch can be activated in
order to minimize fuel consumption and noise
while operating the unit during times of reduced
electrical output, allowing the engine speed to
idle during periods of non-use. The engine speed
returns to normal when an electrical load is
connected. When the economy switch is off, the
engine runs at normal speed continuously.
WARNING
For periods of high electrical load or momentary
fluctuations, the Economy Control Switch should
be turned OFF.

12V DC Outlet (Battery Charger)
The 12V DC outlet is ONLY to be used with the
supplied 12V battery charging cable. The DC
output is unregulated and will damage other
12V DC products.
The amount of current flowing will depend on the
charging voltage and battery's state of charge. As
the battery becomes more fully charged, the output
current to the battery decreases and nearly becomes
constant. Taper chargers are intended to be used
with the provision that they will be disconnected
from the battery after a maximum time on charge.
Normally a period of 30 to 120 minutes is sufficient
to recharge a weak battery. The charge level of the
battery should be checked periodically.
CAUTION
Storage batteries give off EXPLOSIVE hydrogen
gas while charging. Do not allow smoking, open
flames, sparks, or spark producing equipment
in the area while charging.
WARNING
Do not start the vehicle while the battery charging
Cable is connected and the generator is running.
It will not give the battery a boost of power. The
Vehicle or the generator may be damaged. Charge
only vented wet lead acid batteries. Other types
of batteries may burst, causing personal injury
or damage.
Battery electrolyte fluid is comprised of sulfuric
acid that can be very dangerous and cause severe
burns. Do not allow this fluid to contact eyes, skin,
clothing, etc. If contact or spillage does occur,
flush the area with water immediately.
WARNING
1. Before connecting the battery charging cable
to a battery that is installed in a vehicle, disconnect
the vehicle battery ground cable from the
negative (–) battery terminal.
Do not continue to charge a battery that becomes
hot or is fully charged.
A DC circuit protector has been provided to
protect the circuit from overloads. If an overload
occurs, the circuit protector will trip. The circuit
protector may be reset by pushing the button of
the protector.
DC CIRCUIT PROTECTOR
Charging a large capacity battery or a totally
discharged battery may cause the DC breaker to
turn off. In these cases, a separate battery charger
unit connected to an AC power source is
recommended instead of the DC receptacle on
the generator.
NOTE:
When the battery circuit is in use the AC capacity
is reduced by 100 watts. Make sure the combined
load is within the rated limits.
WARNING
Do not continue to charge a battery that becomes
hot or is fully charged.
Stopping the Engine
1. Turn off and remove entire electrical loads.
Never start or stop the generator with
electrical devices plugged in or turned on.
Let the generator run at no-load for two minutes to stabilize
internal temperatures of the engine and generator.
2. Flip the engine switch to“OFF”(O) position.
•For use with 12V direct current outlet, always
keep the ECO mode deactivated (OFF Position).
You can use the 12V direct current outlet and the
230V current at the same time, but keep the ECO
mode deactivated (OFF Position) at all times.
