LPG Hose With Regulator 5 ft. (1.5 m) . . . 1

LPG under pressure is highly flammable and

could 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.

120VAC, 20AMP GFCI RECEPTACLE

This unit is equipped with a ground fault circuit

interrupter (GFCI). This device meets applicable

federal, state and local codes .

A GFCI receptacle does NOT protect against

circuit overloads, short circuits, or shocks. For

example, electric shock can still occur if a person

touches charged electrical wires while standing

on a non-conducting surface, such as a wood floor.

Definition: Instead of following its normal safe

path, electricity passes through a persons body

to reach the ground. For example, a defective

appliance can cause a ground fault.

A GFCI receptacle is different from conventional

receptacles. In the event of a ground fault, a GFCI

will trip and quickly stop the flow of electricity to

prevent serious injury.

1. Plug a test lamp into the receptacle.

2. Start the generator, the test lamp should be on.

3. Press the “Test” button located on the front

of the receptacle to trip the device.

4. This should stop the flow of electricity making

the lamp shut off. The GFCI’s indicator light comes

off.

5. To restore the flow of electricity, press the

“RESET” button on the front of the receptacle.

If the GFCI does not perform in this manner, do

not use the receptacle. Contact a local service

dealer or costumer service.

6. This outlet is protected against overload by

a 20A push-to-reset circuit breaker. Use the

outlet to power 120V AC, single-phase, 60 Hz,

electrical loads requiring up to a combined

2400 watts (2.4 kW) or 20 amps of current.

Testing the GFCI: Test the GFCI outlet every

month as follows:

SELF-TEST OPERATION

A Self-Test GFCI receptacle has all the features

of a conventional GFCI receptacle. In addition,

this receptacle tests itself periodically to confirm

the GFCI electronics are functional. The Indicator

Light will be solid green when the GFCI is powered

from Line side and working correctly.

Self-Test Indications: If the Indicator Light is solid

orange or flashing red a problem may exist.

Press the TEST button to trip the GFCI. If unable to

Reset, replace the GFCI.

*This generator is rated in accordance with CSA (Canadian Standards Association) standard

C22.2 No. 100-14.

Your FIRMAN Power Equipment product is designed and rated for continuous operation at ambient

temperatures up to 104°F (40°C). The generator may be operated at temperatures ranging from

5°F(-15°C) to 122°F(50°C) for short periods. If the generator is exposed to temperatures outside

this range during storage, the generator should be brought back within this range before operation.

When operated above 77°F(25°C) there may be a decrease in power. Maximum wattage and current

are subject to and limited by such factors as ambient temperature, altitude, engine conditions etc.

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.

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.

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.

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.

Observing frost on LPG 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

cylinders

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:

The LPG cylinder can be temporarily warmed

by pouring warm water over the top of the

cylinder.

Exchanging fuel tanks to allow the first tank

to warm up, repeating as necessary

•

Placing the LPG cylinder at the end of the

generator near the handle, where engine fan

air flows out from the generator. This air is

slightly heated by flowing over the engine.

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.

Drain fuel into approved container outdoors,

away from open flame. Be sure engine is cool.

Do not smoke.

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

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

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.

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.

(8) Throughout the emissions warranty period defined in Subsection (b)(2), FIRMAN will maintain a supply of warranted

parts sufficient to meet the expected demand for such parts.

(9) Any replacement part may be used in the performance of any warranty maintenance or repairs and must be provided without

charge to the owner. Such use will not reduce the warranty obligations of the manufacturer.

(10) Add-on or modified parts that are not exempted by the Air Resources Board may not be used. The use of any non-exempted

add-on or modified parts by the ultimate purchaser will be grounds for disallowing a warranty claim.

The manufacturer will not be liable to warrant failures of warranted parts caused by the use of a non-exempted add-on or modified

part.
