Connection

WARNING 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 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.

TIP 9 Follow instructions in the owners manual for the

battery to determine the end of battery charging. 9 Measure the specific gravity of electrolyte to

determine if the battery is fully charged. At full charge, the electrolyte specific gravity is between 1.26 and 1.28.

9 It is advisable to check the specific gravity of the electrolyte at least once every hour to prevent overcharging the battery.

21

Operating range of DC power supply (exclusively for charging 12 V battery) This power source is designed to charge batteries up to 40 Ah that are half-discharged. Do not charge bat- teries of a higher capacity than 40 Ah. 12 V 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 bat- terys specific gravity once an hour. The average time for charging a half-discharged 40 Ah 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 gener- ator which will burn out the coil.

9 Do not connect a VRLA (Valve Regulated Lead Acid) battery. To charge a VRLA battery, a spe- cial (constant-voltage) battery charger is required.

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.

1. 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

2. 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 defi- ciency 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

45

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 instruc- tions 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 repaired or replaced under warranty must be warranted for the remainder of the period prior to the first scheduled replacement point for the part.

(4) Repair or replacement of any warranted part under the warranty must be performed at no charge to the owner at a warranty station.

(5) Notwithstanding the provisions of Subsection (4) above, warranty services or repairs must be provid- ed at all manufacturer distribution centers that are franchised to service the subject engines.

(6) The owner must not be charged for diagnostic labor that leads to the determination that a warranted 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.

(8) Throughout the emissions warranty period defined in Subsection (b)(2), the manufacturer must main- tain a supply of warranted parts sufficient to meet the expected demand for such parts.

(9) Any replacement part may be used in the performance of any warranty maintenance or repairs and 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 non- exempted add-on or modified part.

(11) The manufacturer issuing the warranty shall provide any documents that describe that manufacturers warranty procedures or policies within five working days of request by the Air Resources Board.

The receipts should be trans- ferred 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 invalidat- ing 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 Owners 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.

47

This warranty does not cover damage resulting from accidents, acts of nature, or other events or occur- rences beyond the control of Yamaha. Yamaha Motor Corporation, U.S.A. expressly disclaims responsibili- ty for any and all consequential damages, such as loss of time, inconvenience, loss or use of the SORE engine, or commercial loss.

YAMAHA EXTENDED SERVICE (Y.E.S.)

Keep your Yamaha Generator protected even after your warranty expires with genuine Yamaha Extended Service (Y.E.S.).

9 Y.E.S. is designed and administered by Yamaha Motor Corporation to provide maximum owner satis- faction. You get uninterrupted factory-backed coverage for extra peace of mind.

9 Y.E.S. is flexible. You can choose the plan thats right for you: 12 months, 24 months or 36 months coverage.

9 Y.E.S. is administered by the same Yamaha people that handle your warranty - and it shows in the comprehensive coverage benefits. There are no hour limitations and Y.E.S. covers manufacturing defects just like your warranty. See a sample contract at your Yamaha dealer and see how comfort- ing uninterrupted factory backed protection can be.

9 There are no out-of-pocket expenses for covered repairs. Yamaha will never ask you to pay a deductible.

9 Nationwide coverage. Y.E.S. coverage is honored at any authorized Yamaha Outdoor Power Equipment Service dealer.

9 Y.E.S. coverage is transferable to a new owner if you sell or trade-in. That can make you Yamaha much more valuable.

This excellent Y.E.S. plan coverage is only available to Yamaha owners like you, and only while your Yamaha is still within the Yamaha Limited Warranty period. So visit your authorized Yamaha dealer to get all the facts. He can show you how easy it is to protect your investment with Yamaha Extended Service.

Special note: If visiting your dealer isnt convenient, contact Yamaha with your Primary ID number (your frame number). Well be happy to help you get the Y.E.S. coverage you need.
