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
.
