Operator’s Manual

If this generator is used for standby service, it must have 

a transfer switch between the utility power service and the 

generator. The transfer switch not only prevents the utility 

power form feeding into the generator, but is also prevents the 

generator form feeding out into the utility company’s lines. This 

is intended to protect the serviceman who may be working on 

a damaged line. 
THIS INSTALLATION MUST BE DONE BY A LICENSED 

34-0889

062104-ENG.

This product must be grounded.  If it should malfunction or 

breakdown, grounding provides a path of least resistance for 

electric current to reduce the risk of electric shock.  

The wing nut and ground terminal on the frame must always 

be used to connect the generator to a suitable ground source. 

The ground path should be made with #8 size wire. Connect the 

terminal of the ground wire between the two star washers and 

wing nut then tighten the wing nut fully. Connect the other end 

of the wire securely to a suitable ground source.

The National Electric Code contains several practical ways in 

which to establish a good ground source. Examples given below 

illustrate a few of the ways in which a good ground source may 

be established.

A metal underground water pipe in direct contact with the earth 

for at least 10 feet can be used as a grounding source. If an pipe 

is unavailable, an 8 foot length of pipe or rod may be used as the 

ground source. The pipe should be 3/4 inch trade size or larger 

and the outer surface must be noncorrosive. If a steel or iron rod 

is used it should be at least 5/8 inch diameter and if a nonferrous 

rod is used it should be at least 1/2 inch diameter and be listed 

as material for grounding. Drive the rod or pipe to a depth of 8 

feet. If a rock bottom is encountered less than 4 feet down, bury 

the rod or pipe in a trench. All electrical tools and appliances 

operated from this generator, must be properly grounded by use 

of a third wire or be “Double Insulated”. 

It is recommended to:

1. 

Use electrical devices with 3 prong power cords.

2.    Use an extension cord with a 3 hole receptacle and a 3  

 

prong plug at the opposite ends to ensure continuity of  

 

the ground protection from the generator to appliance.

We strongly recommend that all applicable federal, state and 

local regulations relating to grounding specifications be checked 

and followed.
