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 spe-  
cific questions on operation or maintenance,  
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 identification or  
other valid proof of the original date of purchase. If  
a question or problem arises regarding warranty,  
first contact the owner of the dealership. Since all  
warranty matters are handled at the dealer level,  
this person is in the best position to help you. If you  
are still not satisfied and require additional assis-  
tance, please write:  
Q. Does the warranty cover incidental costs such  
as transportation due to a failure?

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?  
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.  
Cypress, California 90630  
CHANGE OF ADDRESS  
The federal government requires each manufactur-  
er to maintain a complete, up-to-date list of all first  
purchasers against the possibility of a safety-relat-  
ed 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 postcard 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 newYamaha 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:  
1. Check the operation of the generator  
before sale.  
YAMAHA MOTOR CORPORATION, U.S.A.  
WARRANTY DEPARTMENT  
P.O. Box 6555  
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 war-  
ranty repair work.

CONNECTION  
w
Before the generator can be connected to a build-  
ings electrical system, a licensed electrician must  
install an isolation (transfer) switch in the build-  
ings 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 sup-  
ply has failed or has been turned off for line repair.  
Backfeeding can electrocute or injure line mainte-  
nance personnel. Also, generator and building  
electrical system damage can occur when normal  
operating power returns if unit is used without an  
isolation switch.

AE00086  
EXTENSION CORD NOTES  
9 When using an extension cord, its total length  
should not exceed  
60 meters for cross section of 1.5 mm square  
and  
100 meters for cross section of 2.5 mm square.  
9 This extension cord should be protected by a tough  
flexible rubber sheath (IEC 245) or the equivalent  
to withstand mechanical stresses.

Overload indicator light  
The overload indicator light 1 comes on when an over-  
load of a connected electrical device is detected, the  
inverter control unit overheats, or the AC output voltage  
rises.The electronic breaker will then activate, 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.  
760-026  
q
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 application range.  
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:  
9 The generator AC output automatically resets  
when the engine is stopped and then restarted.  
9 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 com-  
pressor or a submergible pump. However, this is  
not a malfunction.  
9 For EF3000iSEB, the overload indicator light may  
flash when using electric devices that require a  
large starting current. However, this is not a mal-  
function. (The flashing indicator is a result of the  
generator temporarily discharging more than its  
rated wattage.)  
While the overload indicator light is flashing, elec-  
tric devices that require a large starting current  
cannot be started.

BATTERY  
This generator is equipped with a sealed-type (MF) bat-

no need to check the electrolyte or to add distilled  
water.  
To charge the battery  
Have a Yamaha dealer charge the battery as soon as  
possible if it seems to have discharged.  
cC  
To charge a sealed-type (MF) battery, a special  
(constant-voltage) battery charger is required.  
Using a conventional battery charger will damage  
the battery. If you do not have access to a sealed-  
type (MF) battery charger, have a Yamaha dealer  
charge your battery.
