ADD ENGINE OIL
Page 12
[CAUTION]
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, level surface.
2.Clean area around oil fill and remove yellow
oil fill cap/dipstick.
3.Wipe dipstick clean.
NOTE:
The recommended oil type is 10W-30 automotive
oil. However outdoor temperatures 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.

DRAIN PLUG
(L)
5.Replace oil fill cap/dipstick and fully tighten.
6.Oil level should be checked prior to each use
or at least every 8 hours of operation. Keep oil
level maintained.
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 13
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.
Do not fill above top of fuel screen. This
will all expansion in hot weather and
prevent overflow.
•
•
•
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
adjusting the engine. At high altitudes
increased exhaust emissions can also result
due to the increased enrichment of the air
fuel ratio.
Other high altitude issues can include hard
starting, increased fuel consumption and
spark plug fouling. To alleviate high
altitude issues other than the natural
power loss, FIRMAN can provide a high
altitude carburetor main jet. The alternative

OPEN
Operation using the alternative main jet at
elevations lower than the recommended
minimum altitude can damage the engine.
For operation at lower elevations, the
standard main jet must be used. Operating
the e n g i n e w i t h th e wr o n g en g i n e
configuration at a given altitude may
increase its emissions and decrease fuel
efficiency and performance.
WARNING
Grounding
The National Electric Code requires your generator
must be properly connected to an appropriate
ground to help prevent electric shock.
Failure to properly ground the
generator can result in electric
shock.
WARNING
A ground terminal connected to the frame of
the generator has been provided on the control

WARNING
Surge Protection
Voltage fluctuation may impair the proper
functioning of sensitive electronic equipment.
Electronic devices, including computers and
many programmable appliances use components
that are designed to operate within a narrow
voltage range and may be affected by momentary
voltage fluctuations. While there is no way to
prevent voltage fluctuations, you can take steps
to protect sensitive electronic equipment.
Install UL1449, CSA-listed, plug-in surge
suppressors on the outlets feeding your
sensitive equipment. Surge suppressors come
in single- or multi-outlet styles. They’re
d e s i g n e d t o p r o t e c t a g a i n s t v i r t u a l l y
all short-duration voltage fluctuations.
WARNING
POISONOUS GAS HAZARD.
Engine exhaust contains carbon
monoxide, a poisonous gas that
could kill you in minutes. You
CANNOT smell it, see it, or taste
it. Even if you do not smell exhaust
fumes, you could still be exposed
to carbon monoxide gas.
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.
Avoid other generator hazards.
READ MANUAL BEFORE USE.
•
DO NOT run this product inside homes,
garages, basements, crawlspaces, sheds, or

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 “START” 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.
Starting the Generator
1. Before starting the generator, check for loose
or missing parts and for any damage which
may have occurred during shipment.
2. Check oil level and fuel.
5. Move the choke lever to the “START” position.
6. Flip the engine switch to the “ON” position.
8. Do not over-choke. As soon as engine starts
and warm up, move the choke lever to the
“RUN” position.
9. Allow generator to run at noload for five
minutes upon each initial start-up to permit
engine and generator to stablize.

single phase, 60Hz electrical loads.
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
Stopping the Engine
1. Remove entire electrical loads.
Never start or stop the generator with
electrical devices plugged in or turned on.
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 two to three hours of operations).
WARNING
2. Let the generator run at no-load for several
minutes to stabilize internal temperatures
of the engine and generator.
3. Turn the fuel valve to the “OFF” position.
If a cover is used, do not install until unit has
cooled.
4. Let the engine run until fuel starvation has
stopped the engine. This usually takes a few
minutes.

Low Oil Shutdown
If the engine oil drops below a preset level, an
oil switch will stop the engine. Check oil level
with dipstick.
If oil level is between LOW and HIGH mark on
dipstick:
1.DO NOT try to restart the engine.
2.Contact an Authorized FIRMAN Service Dealer.
3.DO NOT operate engine until oil level is
corrected.
If oil level is below LOW mark on dipstick:
1.Add oil to bring level to HIGH mark.
2.Restart engine and if the engine stops again
a low oil condition may still exist. DO NOT try
to restart the engine.
3.Contact an Authorized FIRMAN Service Dealer.
4.DO NOT operate engine until oil level is
corrected.
Overloading a generator in excess of its rated
wattage capacity can result in damage to the
generator and to connected electrical devices.
To prolong the life of your generator and
attached devices, follow these steps to add
electrical load:
1. Start the generator with no electrical load
attached.
2. Allow the engine to run for several minutes
to stabilize.
3. Plug in and turn on the first item. It is best to
attach the item with the largest load first.
