Weather

 – Never operate your generator outdoors during 

rain, snow or any combination of weather conditions that 

could lead to moisture collecting on, in or around the 

generator.

Dry Surface

 – Always operate the generator on a dry 

surface free of any moisture.

No Connected Loads

 – Make sure the generator has no 

connected loads before starting it. To ensure there are no 

connected loads, unplug any electrical extension cords that 

are plugged into the control panel receptacles.

NOTICE

Starting the generator with loads already applied to it could result in 

damage to any appliance being powered off the generator during the 

brief start-up period.

Grounding the Generator

 – The National Electric Code (NEC), 

as well as many local electrical codes, may require the generator 

to be connected to earth ground. The most common application 

that requires a ground rod is when you are using the generator 

as a separately derived system to provide back up power to your 

house. Typically this is when a transfer switch has a switched 

neutral.

As the generator application has many variables that cannot 

be determined by the manufacturer of the generator, a licensed 

electrician will need to determine if a grounding rod is needed. 

If a licensed electrician has determined the application requires 

a ground rod, make sure it is connected to earth ground by 

connecting the ground terminal on the control panel to earth 

ground using copper wire (minimum 10 AWG). Consult a qualified 

electrician for local grounding requirements.

WARNING

Be sure the generator is properly connected to 

earth ground before operating. The generator must 

be grounded to prevent electrical shock due to 

faulty appliances.

High Altitude Operation

Engine power is reduced the higher you operate above sea 

level. Output will be reduced approximately 3.5% for every 

1000ft of increased altitude from sea level. This is a natural 

occurrence and cannot be adjusted by engine. Increased 

exhaust emissions can also result due to increased fuel 

mixture. Other issues include hard starting, increased fuel 

consumption and spark plug fouling. 

BEFORE STARTING THE GENERATOR

BEFORE STARTING THE GENERATOR, 

REVIEW SAFETY SECTION STARTING ON 

PAGE 5.

Location Selection

 – Before starting the generator, avoid 

exhaust and location hazards by verifying:
•  You have selected a location to operate the generator 

that is outdoors and well ventilated.

•  You have selected a location with a level and solid 

surface on which to place the generator.

•  You have selected a location that is at least 15 feet 

(4.5 m) away from any building, other equipment or 

combustible material.

•  If the generator is located close to a building, make 

sure it is not located near any windows, doors and/or 

vents.

WARNING

Always operate the generator on a level surface. 

Placing the generator on non level surfaces can 

cause the generator to tip over, causing fuel and 

oil to spill. Spilled fuel can ignite if it comes in 

contact with an ignition source such as a very hot 

surface.

Prolonged exposure to engine exhaust can cause 

serious injury or death. While charging a device 

do not place on the exhaust side of the generator. 

Extreme heat caused by exhaust can damage the 

device, and cause a potential fire hazard. 

NOTICE

Only operate the generator on a solid, level surface. Operating the 

generator on a surface with loose material such as sand or grass 

clippings can cause debris to be ingested by the generator that 

could:

• Block cooling vents

• Block air intake system
