Item 68525 68530

Set up Precautions (cont.)

9.Improper connections to a building electrical system can allow electrical current from the generator to backfeed into the utility lines. Such backfeed may electrocute utility company workers or others who contact the lines during a power outage, and the generator may explode, burn, or cause fires when utility power is restored. Consult the utility company and a qualified electrician if intending to use the generator for back up power.

10.Do not operate the Generator before grounding. The Generator must be earth-grounded

in accordance with all relevant electrical codes and standards before operation.

Operating Precautions

1.CARBON MONOXIDE HAZARD Using a generator indoors CAN KILL

YOU IN MINUTES.

Generator exhaust contains carbon monoxide. This is a poison you cannot see or smell.

NEVER use inside a home or garage, EVEN IF doors and windows are open.

Only use OUTSIDE and far away from windows, doors, and vents.

2.Never use a generator indoors, including in garages, basements, crawlspaces and sheds. Opening doors and windows or using fans will NOT prevent carbon monoxide build up in the home.

3.When using generators, keep them outdoors and far away from open doors, windows, and vents to avoid toxic levels of carbon monoxide from building up indoors.

4.If you start to feel sick, dizzy, or weak while using a generator, get to fresh air right away. The carbon monoxide from generators can quickly lead to full incapacitation and death.

5.Keep children away from the equipment, especially while it is operating.

6.Keep all spectators at least six feet from the Engine during operation.

7.Fire Hazard! Do not fill gas tank while engine is running. Do not operate if gasoline has been spilled. Clean spilled gasoline before starting engine.

Do not operate near pilot light or open flame.

8.Do not touch engine during use. Let engine cool down after use.

9.Never store fuel or other flammable materials near the engine.

10.If the plugged in product operates abnormally or unusually slow, immediately stop using the generator as a power source. Always read and adhere to the instruction manual of the product

to be powered, to make sure that it can be safely and efficiently powered by a portable generator.

11.Before connecting an appliance or power cord to the generator: Make sure that it is in good working order. Faulty appliances or power cords can create a potential for electrical shock.

12.Do not exceed the maximum power rating of the generator. Make sure that the total electrical rating of the all of the tools or appliances plugged into the generator at the same time does not exceed that of the generator. Check that the startup surge will not be beyond the limit of the Generator. Power levels between rated and maximum

may be used for no more than 30 minutes.

13.Avoid substantially overloading which will trip the circuit breaker. Exceeding the time limit for maximum power operation or slightly overloading the generator may not switch the circuit breaker or circuit protector OFF, but will shorten the service life of the generator.

14.Do not attempt to connect or disconnect load connections while standing in water, or on wet or soggy ground.

15.Do not touch electrically energized parts of the Generator and interconnecting cables or conductors with any part of the body, or with any non-insulated conductive object.
