741-090
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 Extension cords should be protected by a tough
flexible rubber sheath (IEC 245) or the equivalent
to withstand mechanical stresses.

WARNING
9 Electrolyte is poisonous and dangerous since
it contains sulfuric acid, which causes severe
burns. Avoid any contact with skin, eyes or
clothing and always shield your eyes when
working near batteries. In case of contact,
administer the following FIRST AID.
9 EXTERNAL: Flush with plenty of water.
9 INTERNAL: Drink large quantities of water or
milk and immediately call a physician.
9 EYES: Flush with water for 15 minutes and
seek prompt medical attention.
9 Batteries produce explosive hydrogen gas.
Therefore, keep sparks, flames, cigarettes,
etc., away from the battery and provide sufficient ventilation when charging it in an
enclosed space.
9 KEEP THIS AND ALL BATTERIES OUT OF THE
REACH OF CHILDREN.
762-012
Operating range of DC power supply
(exclusively for charging 12V battery)
This power source is designed to charge batteries up
to 40Ah that are half-discharged. Do not charge batteries of a higher capacity than 40Ah.
12V battery
The time required for recharging a battery varies
depending on the discharge level of the battery. When
the specific gravity of the battery reaches 1.26 to 1.28,
charging is complete. When charging, check the battery’s specific gravity once an hour.
The average time for charging a half-discharged 40Ah
battery is approximately 5 hours. Be sure to check the
battery fluid level before charging.
NOTICE
9 Do not connect any load to the battery or use
the engine starter motor while charging.
This causes high current to flow through the
generator which will burn out the coil.
9 Do not connect a VRLA (Valve Regulated Lead
Acid) battery. To charge a VRLA battery, a special (constant-voltage) battery charger is
required.

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 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 owners?
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.

Designed, built, and equipped so as to conform, at the time of sale, with all applicable regulations
adopted by the California Air Resources Board, and
All warranted parts are free from defects in material and workmanship for the warranty period of the
SORE engine or the period prior to the first scheduled replacement point of the warranted part as
required by the maintenance schedule, if applicable, whichever is less. A defect exists when a deficiency in material or workmanship is such that an emission-related warranted part does not function
as designed.
The warranty period begins on the date that the SORE engine is delivered to an ultimate purchaser or on
the date it is first placed in service.
The warranty on emissions-related parts will be interpreted as follows:
(1) Any warranted part that is not scheduled for replacement as required maintenance in the written

instructions required by subsection (d) must be warranted for the warranty period defined in
Subsection (b)(2). If any such part fails during the period of warranty coverage, it must be repaired or
replaced by the manufacturer according to Subsection (4) below. Any such part repaired or replaced
under the warranty must be warranted for the remaining warranty period.
(2) Any warranted part that is scheduled only for regular inspection in the written instructions required by
subsection (d) must be warranted for the warranty period defined in Subsection (b)(2). A statement in
such written instructions to the effect of “repair or replace as necessary” will not reduce the period of
warranty coverage. Any such part repaired or replaced under warranty must be warranted for the
remaining warranty period.
(3) Any warranted part that is scheduled for replacement as required maintenance in the written instructions required by subsection (d) must be warranted for the period of time prior to the first scheduled
replacement point for that part. If the part fails prior to the first scheduled replacement, the part must
be repaired or replaced by the engine manufacturer according to Subsection (4) below. Any such

part is in fact defective, provided that such diagnostic work is performed at a warranty station.
(7) The manufacturer is liable for damages to other engine components proximately caused by a failure
under warranty of any warranted part.

must be provided without charge to the owner. Such use will not reduce the warranty obligations of
the manufacturer.
(10) Add-on or modified parts that are not exempted by the Air Resources Board may not be used. The
use of any non-exempted add-on or modified parts will be grounds for disallowing a warranty claim.
The manufacturer will not be liable to warrant failures of warranted parts caused by the use of a nonexempted add-on or modified part.
(11) The manufacturer issuing the warranty shall provide any documents that describe that manufacturer’s
warranty procedures or policies within five working days of request by the Air Resources Board.

DURING THE PERIOD OF THIS WARRANTY
Yamaha Motor Corporation, U.S.A. will repair or replace any warranted part deemed defective by Yamaha
during the scope of the warranty without charge to the owner, including parts, labor, and diagnosis. This
work must be done at an authorized Yamaha dealer. Give notice to an authorized Yamaha dealer of any
apparent defects(s) within a reasonable period of time after discovery. The SORE engine must be made
available for inspection by an authorized Yamaha dealer.
OWNER’S RESPONSIBILITY:
The owner of the SORE engine is responsible for the performance of required maintenance (see your
Owner’s Manual). Receipts and maintenance records covering the performance of regular maintenance
should be retained in the event questions arise concerning maintenance. The receipts should be transferred to each subsequent owner of this SORE engine.
The emission control systems of your Yamaha SORE engine were designed, built, tested, and certified as
being in conformity with California emission control regulations using genuine Yamaha parts. Accordingly,
it is recommended that any replacement part(s) used for maintenance, replacement, or repair of emission
control systems be Yamaha parts. The owner may elect to have maintenance, replacement, or repair of
the emission control devices and systems performed by any repair establishment or individual, and may
elect to use parts other than Yamaha parts for such maintenance, replacement, or repair without invalidating this warranty. However, the cost of such service or parts will not be covered under the warranty.
EXCLUSIONS: No warranty coverage will be allowed if the part(s) failure was caused by owner/operator
abuse, neglect, tampering, improper adjustment unless performed by a dealer during warranty repair
work, modification, misuse, alteration, or improper maintenance (see your Owner’s Manual).
Use of parts which are not qualitatively equivalent to genuine Yamaha parts, improper service, or lack of
required maintenance which causes failure of a warranted part may constitute abuse and/or improper service, thereby invalidating warranty liability hereunder.
