Equipment Description

The generator is an engine–driven, revolving field,

alternating current (AC) generator. It was designed to supply

electrical power for operating compatible electrical lighting,

appliances, tools and motor loads. The generator’s revolving

field is driven at about 3,600 rpm by a single-cylinder

engine. The generator is operated on liquefied propane (LP)

gas.

This generator incorporates GFCI (Ground Fault Circuit

Interrupter) outlet protection and has its neutral bonded to

grounding fastener to comply to OSHA inspections on job

sites.

WARNING Electrical Shock Hazard. GFCI will not

function if neutral bond is removed, which could

result in death or serious injury.

DO NOT remove the neutral bond.•

Removing the neutral bond could result in death, bodily •

injury and/or property damage.

This generator will not function when connected to a 2

pole transfer switch since its service disconnect also has

a neutral bonded to ground. When both the generator and

the home or building’s service disconnect contains a neutral

bonded to ground, the generator’s GFCI will open and no

outlets will function.

A switching neutral transfer switch MUST be used if the

generator is connected to a building’s electrical system.

This product is intended for residential use as an all-

weather temporary source of electric power. It is capable

of supplying power to loads such as heating, refrigeration

systems, and communication systems. This product does

not qualify for emergency standby as defined by NFPA 70

(NEC). DO NOT use this generator for anything other than

it’s intended purpose.

Every effort has been made to ensure that the information

in this manual is both accurate and current. However, the

manufacturer reserves the right to change, alter or otherwise

improve the generator and this documentation at any time

without prior notice.

Ground Fault Protection

The generator’s receptacles are equipped with Ground Fault

Circuit Interrupter (GFCI) protection. This GFCI device meets

applicable federal, state and local codes.

The GFCI protects against electrical shock that may be

caused if your body becomes a path in which electricity

travels to reach the ground. This could happen if you touch

a “Live” appliance or wire, or are touching plumbing or

other materials that connect to the ground.

When protected by a GFCI device, one may still feel a shock,

but the GFCI should cut current off quickly enough so that

a person in normal health should not suffer any serious

electrical injury.

WARNING Electrical Shock Hazard. Generator voltage

could cause electrical shock or burn resulting in death

or serious injury.

Contact with the hot and neutral conductor at the same •

time can cause electrical shock or burn, even if the circuit

is GFCI protected.

Before using the GFCI receptacle, ALWAYS push the test •

button to insure it works.

Connections to a Building’s Electrical System

Connections from this generator to a building’s electrical

system must be made through a switching neutral transfer

switch installed by a qualified electrician. The connection

must isolate the generator power from utility power, and

must comply with all applicable laws and electrical codes.

NOTICE A switching neutral transfer switch MUST be used

when switching between utility and generator power.

Don’t Overload Generator

Capacity

You must make sure your generator can supply enough rated

(running) and surge (starting) watts for the items you will

power at the same time. Follow these simple steps.

1. Select the items you will power at the same time.

2. Total the rated (running) watts of these items. This is

the amount of power your generator must produce to

keep your items running.

3. Estimate how many surge (starting) watts you will need.

Surge wattage is the short burst of power needed to

start electric motor-driven tools or appliances such as a

circular saw or refrigerator. Because not all motors start

at the same time, total surge watts can be estimated by

adding only the item(s) with the highest additional surge

watts to the total rated watts from step 2.

Example:

Total Rated (Running) Watts = 3075

Highest Additional Surge Watts = 1800

Total Generator Output Required = 4875

Power Management

To prolong the life of your generator and attached devices,

it is important to take care when adding electrical loads to

your generator. There should be nothing connected to the

generator outlets before starting it’s engine. The correct and

safe way to manage generator power is to sequentially add

loads as follows:

1. With nothing connected to the generator, start the

engine as described in this manual.

2. Plug in and turn on the first load, preferably the largest

load you have.

3. Permit the generator output to stabilize (engine runs

smoothly and attached device operates properly).

4. Plug in and turn on the next load.

5. Again, permit the generator to stabilize.

6. Repeat steps 4 and 5 for each additional load.
