CONNECTION  
w
Before the generator can be connected to a build-  
ing’s electrical system, a licensed electrician must  
install an isolation (transfer) switch in the build-  
ing’s main fuse box. The switch is the connection  
point for generator power and allows selection of  
generator or main line power to the building. This  
will prevent the generator from charging the main  
power line (backfeeding) when the main power  
supply has failed or has been turned off for line  
repair. Backfeeding can electrocute or injure line  
maintenance personnel. Also, generator and build-  
ing electrical system damage can occur when nor-  
mal operating power returns if unit is used without  
an isolation switch.

EXTENSION CORD NOTES  
Extension cords should be protected by a tough flexi-  
ble rubber sheath (IEC 245) or the equivalent to with-  
stand mechanical stresses.

NOTE:  
If you operate the generator with the voltage select  
switch in the 120/240V-position, the electric current  
will be limited for the 120V-receptacles.  
When you use either receptacle 1 or 2 AND recepta-  
cle 3 at the same time, the total electric current pro-  
vided will be equal to or even less than 22.9A.  
For example:

793-7CKf  
If the 240V-receptacle provides 10A, the 120V-recep-  
tacles 1 and 2 can be used up to 12.9A each.  
In case the load exceeds 22.9A, the overload indicator  
light will turn on and the generator will stop. (At this  
moment the segments of the powermeter may not  
reach 10)  
If you operate the generator with the voltage select  
switch in the 120V-position, the receptacles 1 and 2  
can supply rated current (45.8A).

Overload indicator light (red)  
The overload indicator light 1 comes on when an  
overload of a connected electrical device is detected,  
the inverter control unit overheats, or the AC output  
voltage rises. Then, the AC protector will trip, stopping  
power generation in order to protect the generator and  
any connected electric devices. The AC pilot light  
(green) will go off and the overload indicator light (red)  
will stay on, but the engine will not stop running.  
763-7CKd  
When the overload indicator light comes on and power  
generation stops, proceed as follows:  
1. Turn off any connected electric devices and stop  
the engine.  
2. Reduce the total wattage of connected electric  
devices within the rated output.  
3. Check for blockages in the cooling air inlet and  
around the control unit. If any blockages are  
found, remove.  
4. After checking, restart the engine.  
NOTE:  
The overload indicator light may come on for a few  
seconds at first when using electric devices that  
require a large starting current, such as a compressor  
or a submergible pump. However, this is not a mal-  
function.

WARRANTY QUESTIONS AND ANSWERS  
Q. What costs are my responsibility during the  
Q. Is the warranty transferable to second own-  
warranty period?  
ers?  
A. The customer’s responsibility includes all  
costs of normal maintenance service, non-  
warranty repairs, accident damages, as well  
as oil and spark plugs.  
A. Yes. The remainder of the existing warranty  
can be transfered upon request.  
The unit has to be inspected and reregistered  
by an authorized Yamaha generator dealer for  
the policy to remain effective.  
Q. What are some examples of “abnormal” strain,  
neglect, or abuse?  
CUSTOMER SERVICE  
A. These terms are general and overlap each  
other in areas. Specific examples include:  
Running the machine out of oil; lack of proper  
maintenance; operating the machine with a  
broken or damaged part which causes anoth-  
er part to fail; and so on. If you have any  
specific questions on operation or mainte-  
nance, please contact your dealer for advice.  
If your machine requires warranty service, you  
must take it to any authorized Yamaha generator  
dealer within the continental United States. Be  
sure to bring your warranty registration identifica-  
tion or other valid proof of the original date of pur-  
chase. If a question or problem arises regarding  
warranty, first contact the owner of the dealership.  
Since all warranty matters are handled at the deal-  
er level, this person is in the best position to help  
you. If you are still not satisfied and require addi-  
tional assistance, please write:  
Q. Does the warranty cover incidental costs such  
as transportation due to a failure?  
A. No. The warranty is limited to repair of the  
machine itself.

CUSTOMER RELATIONS DEPARTMENT  
P.O. BOX 6555  
Q. May I perform any or all of the recommended  
maintenance shown in the Owner’s Manual  
instead of having the dealer do them?  
Cypress, California 90630  
A. Yes, if you are a qualified mechanic and follow  
the procedures specified in the Owner’s and  
Service Manual. We do recommend, however,  
that items requiring special tools or equipment  
be done by a Yamaha generator dealer.  
CHANGE OF ADDRESS  
The federal government requires each manufac-  
turer to maintain a complete, up-to-date list of all  
first purchasers against the possibility of a safety-  
related defect and recall. This list is compiled from  
the purchase registrations sent to Yamaha Motor  
Corporation, U.S.A. by the selling dealer at the  
time of your purchase. If you should move after  
you have purchased your new generator, please  
advise us of your new address by sending a post-  
card listing your Yamaha model name, engine  
number, dealer number (or dealer’s name) as it is  
shown on your warranty identification, your name  
and new mailing address. Mail to:  
Q. Will the warranty be void or cancelled if I do  
not operate or maintain my new Yamaha  
exactly as specified in the Owner’s Manual?  
A. No. The warranty on a new Yamaha cannot  
be “voided” or “cancelled.”  
However, if a particular failure is caused by  
operation or maintenance other than as  
shown in the Owner’s Manual, that failure  
may not be covered under warranty.  
Q. What responsibility does my dealer have  
under this warranty?  
A. Each Yamaha generator dealer is expected  
to:  
YAMAHA MOTOR CORPORATION, U.S.A.  
WARRANTY DEPARTMENT  
P.O. Box 6555  
1. Check the operation of the generator  
before sale.  
Cypress, California 90630  
2. Explain the operation, maintenance, and  
warranty requirements to your satisfaction  
at the time of sale, and upon your request  
at any later date.  
This will ensure that Yamaha Motor Corporation,  
U.S.A. has an up-to-date registration record in  
accordance with federal law.  
In addition, each Yamaha generator dealer is  
held responsible for his setup, service and  
warranty repair work.
