Fuel Safety

Gasoline:

DANGER

GASOLINE AND GASOLINE VAPORS ARE HIGHLY

FLAMMABLE AND EXPLOSIVE.

Fire or explosion can cause severe burns or death.

Unintentional startup can result in entanglement,

traumatic amputation or laceration.

Gasoline can cause a fire or explosion if ignited.

•

Gasoline is a liquid fuel but it’s vapors can ignite.

•

Gasoline is a skin irritant and needs to be cleaned

up immediately if spilled on skin or clothes.

•

Gasoline has a distinctive odor, this will help

detect potential leaks quickly.

•

In any gasoline fire, flames should not be

extinguished unless by doing so the fuel supply

valve can be turned OFF. This is because if a fire is

extinguished and a supply of fuel is not turned OFF,

then an explosion hazard could be created.

Gasoline expands or contracts with ambient

•

temperatures. Never fill the gasoline tank to

full capacity, as gasoline needs room to expand

if temperatures rise.

Liquid Petroleum Gas (LPG/Propane):

This generator is dual fuel and capable of running

with both gasoline and Liquid Petroleum Gas

(LPG/Propane).

DANGER

Liquid Petroleum Gas (LPG) is highly flammable

•

and explosive. Fire or explosion can cause severe

burns or death.

Do not use or store LPG cylinder in a building,

•

garage or enclosed area.

•

Do not check for leaks with a lighted match or

flame.

The LPG cylinder valve should be fully closed

•

when the generator is not in use or is running

with gasoline.

If you smell gas: close off the gas supply. Make

•

sure there is no leak before using the generator.

Device used for handling LPG must be installed

•

WARNING

and used in strict conformance with NFPA 58

(Liquefied Petroleum Gas Code) and NFPA 54

(National Fuel Gas) and all other codes, regulations

and manufacturer recommendations.

Never use a gas container, LPG connector

•

hose, LPG cylinder or any other fuel item that

is damaged or appears damaged.

The LPG cylinder valve should be fully closed

when the generator is not in use or is running

with gasoline.

•

The regulator/hose assembly and cylinder

valve must be inspected before each use for

leaks or sign of damages.

If you smell gas: close off the gas supply. Spray

•

a soapy water solution to check all connections

for leaks before attempting to use generator.

Contact a qualified technician to inspect and

repair the LPG system if a leak found before

using the generator.

CAUTION

LPG under pressure is highly flammable and

•

can cause a fire or explosion if ignited.

•

LPG is heavier than air and can accumulate in

confined spaces and low places in the event

of a leak.

LPG has a distinctive odor to help detect

potential leaks.

Do not allow children to tamper or play with

the LPG cylinder.

In the event of an LPG fire, flames should not

•

be extinguished unless by doing so the fuel

supply valve can be turned off. If the fire is

extinguished and a supply of fuel is not turned

off, an explosion hazard greater than the fire

hazard could be created.

•

Keep a fire extinguisher near the generator all

the time.

Always keep the LPG cylinder in an upright

position.

Do not subject LPG cylinder to excessive heat.

•

Contact with liquid contents of the cylinder

will cause freeze burns to the skin.

An LPG cylinder not connected for use shall

not be stored in the vicinity of the generator.

When transporting and storing, turn off the

cylinder valve and fuel selector switch, and

disconnect the cylinder.

ADD FUEL

1.Gasoline

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.

Avoid generator damage.

Failure to follow Operator's Manual for fuel

recommendations voids warranty.

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.

•

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 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.

You must use the supplied regulator/hose

assembly for safe operation.

Always position the cylinder so the connection

between the valve and the regulator won’t cause

bends or kinks in the hose.

Spray a soapy water solution (one part liquid

detergent and one part water) to check all

connections for leaks before attempting to

use generator. Slowly open the cylinder valve.

A leak exists if bubbles appear or grow larger

in size or number. This must be corrected before

3-Permanent Connection to a large

Propane supply tank:

In the instance that you would need to connect

your generator to a large propane Supply tank,

larger than 20 or 30 lb DOT cylinder, it is

recommended to contact your Gas Equipment

Company. Various equipment for use with LPG,

is required for proper conformance to all NFPA

regulations. Your Gas Equipment Company can

help you select and install the proper regulator,

fittings and connections to meet all the Codes

and manufacturer regulations. Each installation

may be different and will required proper equipment.

Contact your Gas Equipment Company to assure

that you are meeting all NFPA 58 (Liquefied

Petroleum Gas Code) and NFPA 54 (National Fuel

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

sp ar k p l ug fo uli ng . To al lev ia t e h ig h

engine and generator to stablize.

Connecting Electrical Loads

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).

1.Let engine stabilize and warm up for a few

minutes after starting.

2.Ensure circuit breaker on control panel is in

on position.

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.

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 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.

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. Turn the fuel selector switch to OFF (O)position.

Customer Service: 1-844-FIRMAN1

NOTE:

Observing frost on LPG cylinders and regulators

is common during operation and normally is not

an indication of a problem. As LPG vaporizes and

travels from the tank to the generator engine it

expands. The amount of frost that forms can be

affected by the size of the cylinder, the amount

of fuel being used, the humidity of the air and other

operating conditions. In unusual situations this

frost may eventually restrict the flow of LPG gas

to the generator resulting in deteriorating

performance. For example, if the tank temperature

is reduced to a very low level then the rate at which

the LPG vaporizes is also reduced and may not

provide sufficient fuel flow to the engine. This is

not an indication of a problem with the generator

but only a problem with the flow of gas from the

LPG cylinder. If generator performance seems

to be deteriorating at the same time that ice

formation is observed on tank valve, hose or

regulator then some actions may be taken to

eliminate this symptom. In these rare situations

it can be helpful to reduce or eliminate the cold

fuel system effects by doing one of the following:

Exchanging fuel tanks to allow the first tank

SERVICE AND STORAGE

Infrequent Service

If the unit is used infrequently, difficult starting

may result. To eliminate hard starting, follow

these instructions:

1. Run the generator at least 30 minutes every

month.

2. Run the generator, then close the fuel shut-off

valve and allow the unit to run until the engine

stops.

3. Move the fuel selector to the "OFF" position.

Long Term Storage

It is important to prevent gum deposits from forming

in essential fuel system parts such as the carburetor,

fuel hoses or tank during storage. Also, experience

indicates that 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.

When the generator set is not being operated,

or is being stored for more than one month, follow

these instructions to avoid engine problems:

1-ADD a properly formulated commercially FUEL

STABILIZER to the tank if it is not already added.

2-Operate the engine for 5-10 minutes to circulate

treated fuel into fuel lines and carburetor before

shutdown.

3- After engine cools down, remove all gasoline

from the fuel tank. Use a commercially available,

non-conductive vacuum siphon.

4-FUEL STARVATION: Turn fuel selector switch

to “GAS” position. Start and run the generator until it

stops from lack of gasoline. This will dry out all

remaining gasoline in tank, fuel lines and carburetor.

5-Turn fuel selector switch to “OFF” position.

Fully close the LPG cylinder knob if it is open and

disconnect LPG cylinder from the generator.

6-Allow the unit to cool entirely before cleaning

and storage.

7-Change oil with recommended grade oil.

8-Remove spark plug and pour about one teaspoon

of engine oil through the spark plug hole, then pull

the recoil starter several times to distribute the oil for

lubricating the cylinder. Reattach the spark plug.

Pull recoil slowly until resistance is felt. This will

close the valves so moisture cannot enter engine

cylinder. Gently release recoil starter.

9-Cover the unit and store in a clean, dry place

out of direct sunlight. NEVER USE WATER TO

CLEAN GENERATOR.

Note:

•

We recommend always using a fuel stabilizer.

A FUEL STABLIZER will minimize the formulation

of fuel gum deposits during storage, the fuel

stabilizer can be added to the gasoline in the

fuel tank, or into the gasoline in a storage

container.

•

If it is not practical to empty the fuel tank and

the unit is to be stored for some time, use a

commercially available FUEL STABILIZER added

to the gasoline to increase the life of the gasoline.

Run the unit for 5-10 minutes to circulate treated

gasoline into the fuel lines abs carburetor before

shutdown. DO NOT STORE GENERATOR WITHOUT

FUEL STABILIZER IN FUEL SYSTEM INCLUDING

TANK, FUEL LINES AND CARBURETOR.

Any damages or hazards caused by using

•

improper fuel, improperly stored fuel, and/

or improperly formulated stabilizers, are not

covered by manufacturer's warranty.

•

Do not store gasoline from one season to

another season.

DANGER

Drain fuel into approved container outdoors,

away from open flame. Be sure engine is cool.

Do not smoke.

Battery Charging & Maintenance

The battery powers up the starter motor and the control

module in this generator. This product is equipped with

an automatic battery charging circuit. The battery will

receive charging voltage when the engine is running.

The battery will maintain a proper charge if the unit is

used on a regular basis (about once every two weeks).

If it is used less frequently, the battery should be connected

to a trickle charger (not included) or battery maintainer (not

included) to keep the battery properly charged. If the

battery is not able to start the engine, it can be started

manually only on “GAS” position by pulling the engine

recoil cord. If the battery voltage is extremely low, the

charging circuit may not be able to re-charge the battery.

In this case, the battery must be connected to a standard

automotive style battery charger for re-charging before

it can be used.

WARNING

Generator exhaust contains odorless and

colorless carbon monoxide gas.

To avoid accidental or unintended ignition of

your generator during periods of storage, the

following precautions should be followed:

When storing the generator for short or extended

periods of time make sure that the fuel selector

switch is in the “OFF” position and the battery

leads have been disconnected from the battery.

FIRMAN POWER EQUIPMENT INC.

Emission Control System Warranty

CALIFORNIA AND FEDERAL EXHAUST AND EVAPORATIVE EMISSIONS CONTROL WARRANTY STATEMENT

YOUR WARRANTY RIGHTS AND OBLIGATIONS

The California Air Resources Board, US Environmental Protection Agency (“US EPA”) and FIRMAN POWER EQUIPMENT

INC.(FIRMAN) are pleased to explain the emissions control systems warranty on your 2024 -2025 or later Small Off-Road

Engine (“SORE”) and engine powered equipment. In California, new equipment that use small off-road engines must be

designed, built and equipped to meet the State’s stringent anti-smog standards. FIRMAN must warrant the emissions control

systems on your SORE and engine powered equipment for the periods of time listed below provided there has been no abuse,

neglect or improper maintenance of your small off-road engine or equipment leading to the failure of the emissions control system.

Your emissions control system may include parts such as the carburetor or fuel-injection system, the ignition system, catalytic

converter, fuel tanks, fuel lines (for liquid fuel and fuel vapors), fuel caps, valves, canisters, filters, clamps and other associated

components. Also included may be hoses, belts, connectors, and other emission-related assemblies.

Where a warrantable condition exists, FIRMAN will repair your SORE and engine powered equipment at no cost to you

including diagnosis, parts and labor.

MANUFACTURER'S WARRANTY COVERAGE:

The exhaust and evaporative emissions control system on your small off-road engine and engine powered equipment is warranted

for two years. If any emissions-related part on your small off-road engine and engine powered equipment is defective, the part will

be repaired or replaced by FIRMAN.

OWNER'S WARRANTY RESPONSIBILITIES:

As the SORE and engine powered equipment owner, you are responsible for the performance of the required maintenance

listed in your owner's manual. FIRMAN recommends that you retain all receipts covering maintenance on your SORE and

engine powered equipment, but FIRMAN cannot deny warranty coverage solely for the lack of receipts or for your failure to

ensure the performance of all scheduled maintenance.

As the SORE and engine powered equipment owner, you should however be aware that FIRMAN may deny you warranty

coverage if your small off-road engine or engine powered equipment or a part has failed due to abuse, neglect, or improper

maintenance or unapproved modifications.

You are responsible for presenting your small off-road engine and engine powered equipment to a FIRMAN distribution center

or service center as soon as the problem exists. The warranty repairs shall be completed in a reasonable amount of time,

not to exceed 30 days.

If you have any questions regarding your warranty rights and responsibilities, you should contact FIRMAN at 1-844-347-6261

or support@firmanpowerequipment.com.

FIRMAN Emission Control Defects Warranty Provisions

The warranty period begins on the date the engine/equipment is delivered to an ultimate purchaser. FIRMAN warrants to the ultimate

purchaser and each subsequent purchaser that the engine is:

Designed, built, and equipped so as to conform with all applicable regulations adopted by the Air Resources Board and US EPA;

and Free from defects in materials and workmanship that cause the failure of a warranted part to be identical in all material

respects to the part as described in the engine manufacturers application for certification.

The warranty on emissions-related parts is as follows:

(1) Any warranted part that is not scheduled for replacement as required maintenance in the owner's manual supplied, is

warranted for the warranty period stated above. If any such part fails during the period of warranty coverage, the part will be

repaired or replaced by FIRMAN at no charge to the owner. Any such part repaired or replaced under the warranty will be

warranted for the remaining warranty period.

(2) Any warranted part that is scheduled only for regular inspection in the owner's manual supplied, is warranted for the warranty

period stated above. Any such part repaired or replaced under warranty will be warranted for the remaining warranty period.

(3) Any warranted part that is scheduled for replacement as required maintenance in the owner's manual supplied, is warranted

for the period of time prior to the first scheduled replacement point for that part. If the part fails prior to the first scheduled
