ADD ENGINE OIL
Page 14
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 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.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 15
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.
English Customer Service: 1-844-FIRMAN1
CAUTION
Slowly add unleaded gasoline to fuel tank.
Do not overfill tank.
Do not fill above the red line indicator.
This will allow expansion in hot weather
and prevent overflow.

•
Red Line Indicator
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.
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

Starting the Generator (Recoil Start)
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.
7. Move the choke lever to the “START” position.
5. Flip the engine switch to the “RUN(l)” position.
9. Do not over-choke. As soon as engine starts
and warms up, move the choke lever to the
“RUN” position.
10. Allow generator to run at no load for few
minutes upon each initial start-up to permit
engine and generator to stablize.
WARNING
When starting engine, pull cord slowly until
resistance is felt and then pull rapidly to avoid
kickback.
4. Turn the fuel valve to the “ON” (l)position.
8. Pull the starter cord slowly until resistance is
felt and then pull rapidly.
3. Disconnect all electrical loads from the
generator. Never start or stop the generator
with electrical devices plugged in or turned
on.
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.
6. Flip the battery switch to the "ON"(l) position.
