YAMAHA MOTOR CORPORATION U.S.A.
EF- AND EDL-SERIES GENERATOR LIMITED WARRANTY
Yamaha Motor Corporation, U.S.A. hereby warrants that new Yamaha consumer generators
purchased from an authorized Yamaha consumer generator dealer in the continental United

THE PERIOD OF WARRANTY Any new EFseries or EDL-series Yamaha Generator purchased for private, non-commercial use from an
authorized Yamaha consumer generator dealer
in the continental United States will
be warranted against defects in material or workmanship for a period two (2) years from date of
purchase, subject to exclusions noted herein.
Any Yamaha non-commercial
generator purchased and utilized for commercial
or rental applications will be warranted for a period one (1) year from the date of purchase, subject to exclusions noted herein.
DURING THE PERIOD OF WARRANTY any
authorized Yamaha consumer generator dealer
will, free of charge, repair or replace, at
Yamaha’s option, any part adjudged defective by
Yamaha due to faulty workmanship or material
from the factory. Parts used in warranty repairs
will be warranted for the balance of the product’s
warranty period. All parts replaced under warranty become property of Yamaha Motor
Corporation U.S.A.
GENERAL EXCLUSIONS from this warranty
shall include any failures caused by:
a. Installation of parts or accessories that are
not qualitatively equivalent to genuine
Yamaha parts.
b. Abnormal strain, neglect, or abuse.
c. Lack of proper maintenance.
d. Accident or collision damage.
SPECIFIC EXCLUSIONS from this warranty
shall include parts replaced due to normal wear
or routine maintenance.
THE CUSTOMER’S RESPONSIBILITY under
this warranty shall be to:
1. Operate and maintain the generator as spec-
ified in the appropriate Owner’s Manual;
2. Give notice to an authorized Yamaha consumer generator dealer of any and all apparent defects within ten (10) days after discovery, and make the unit available at that time
for inspection and repairs at such dealer’s
place of business.
WARRANTY TRANSFER: To transfer the warranty from the original purchaser to any subsequent purchaser(s), it is imperative that the unit
be inspected and registered for warranty by an
authorized Yamaha consumer generator dealer.
In order for this warranty to remain in effect, this
inspection and registration must take place within ten (10) days after transfer. An inspection and
registration fee will be charged for this service.
In no case will the warranty be extended beyond
the original period.
YAMAHA MOTOR CORPORATION, U.S.A.

WARRANTY QUESTIONS AND ANSWERS
Q. What costs are my responsibility during the
warranty period?
A. The customer’s responsibility includes all
costs of normal maintenance service, nonwarranty repairs, accident damages, as well
as oil and spark plugs.
Q. What are some examples of “abnormal”
strain, neglect, or abuse?
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
another part to fail; and so on. If you have
any specific questions on operation or maintenance, please contact your dealer for
advice.
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.
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 fol-
low 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.
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:
1. Check the operation of the generator
before sale.
2. Explain the operation, maintenance, and
warranty requirements to your satisfaction at the time of sale, and upon your
request at any later date.
In addition, each Yamaha generator dealer is
held responsible for his setup, service and
warranty repair work.
Q. Is the warranty transferable to second own-
ers?
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.

CONNECTION
w
Before the generator can be connected to a building’s electrical system, a licensed electrician must
install an isolation (transfer) switch in the building’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 building electrical system damage can occur when normal operating power returns if unit is used without
an isolation switch.

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
or more.
9 This extension cord should be protected by a
tough flexible rubber sheath (IEC 245) or the
equivalent to withstand mechanical stresses.
