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, non-
warranty 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 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.
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 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.
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.
CUSTOMER SERVICE
If your machine requires warranty service, you
must take it to any authorized Yamaha generator
dealer within the continental United States. Be

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:

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.
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.

NOTE:
If the engine stalls or does not start, turn the engine
switch to "ON" position and then pull the recoil starter.
If the oil warning light flickers for a few seconds, the
