IMPORTANT SAFETY INSTRUCTIONS

SPECIFIC SAFETY RULES

 DANGER:

Risk of fire and serious burns: 

Never remove fuel cap 

when unit is running. Shut off engine and allow the unit 

to cool at least five minutes. Remove cap slowly.

 WARNING:

When this generator is used to supply a building 

wiring system:

 generator must be installed by a quali-

fied electrician and connected to a transfer switch as 

a separately derived system in accordance with NFPA 

70, National Electrical Code. The generator shall be 

connected through a transfer switch that switches all 

conductors other than the equipment grounding con-

ductor. The frame of the generator shall be connected to 

an approved grounding electrode. Failure to isolate the 

generator from power utility can result in death or injury 

to electric utility workers. 

 

Do not use this generator to provide power for emergency 

medical equipment or life support devices.

 

This generator has a neutral floating condition. This means 

the neutral conductor is not electrically connected to the 

frame of the machine.

 

Always use a battery-powered carbon monoxide detec-

tor when running the generator. If you begin to feel sick, 

dizzy, or weak while using the generator, shut it off and 

get to fresh air immediately. See a doctor. You may have 

carbon monoxide poisoning.

 

Place the generator on a flat, stable surface with a slope 

of no more than 4°.

 

Operate outdoors in a well-ventilated, well-lit area isolated 

from working areas to avoid noise interference.

 

Operating the generator in wet conditions could result in 

electrocution. Keep the unit dry.

 

Keep the generator a minimum of 3 feet away from all 

types of combustible material. 

 

Do not operate generator near hazardous material.

 

Do not operate generator at a gas or natural gas filling 

station.

 

Do not touch the muffler or cylinder during or immediately 

after use; they are HOT and will cause burn injury.

 

Do not allow the generator’s gas tank to overflow when 

filling. Fill to 1 in. below the top neck of the gasoline tank 

to allow for fuel expansion. 

 

Do not smoke when filling the generator with gasoline.

 

Shut down the engine and allow to cool for five minutes 

before adding gasoline or lubricant to the generator.

 

Do not remove the oil dipstick or the fuel tank cap when 

the engine is running.

 

Pay close attention to all safety labels located on the 

generator.

 

Keep children a minimum of 10 feet away from the gen-

erator at all times.

 

The unit operates best in temperatures between 23°F and 

104°F with a relative humidity of 90% or less.

 

Operating voltage and frequency requirement of all 

electronic equipment should be checked prior to plug-

ging them into this generator. Damage may result if the 

equipment is not designed to operate within a +/- 10% 

voltage variation, and +/- 3 hz frequency variation from the 

generator name plate ratings. To avoid damage, always 

have an additional load plugged into the generator if 

solid state equipment (such as a television set) is used. 

A power line conditioner is recommended for some solid 

state applications.

 

For outdoor use only.

 

NEVER ignore an automatic shutoff event. IF AUTOMATIC 

SHUTOFF OCCURS – YOU MUST leave the area imme-

diately and relocate to an open outdoor area. Ventilate 

the area thoroughly before occupying again. Ensure the 

generator is located in an open, outdoor area. Always 

point exhaust away from occupied structures. Never 

run the generator in enclosed areas (e.g. not in a house 

or garage). Failure to follow these instructions can lead 

to carbon monoxide (CO) poisoning which can result in 

death or serious personal injury.

 

For power outages, permanently installed stationary gen-
erators are better suited for providing back-up power to 
the home. Even a properly connected portable generator 
can become overloaded. This may result in overheating 
or stressing the generator components, possibly leading 
to generator failure.

 

Use only recommended or equivalent replacement parts 
and accessories and follow instructions in the  

Maintenance

section of this manual. Use of any other parts or failure 
to follow maintenance instructions may create a risk of 
shock or injury.

 

Maintain the unit per maintenance instructions in this 
Operator’s Manual.

 

Inspect the unit before each use for loose fasteners, fuel 
leaks, etc. Replace damaged parts.
