CONNECTION NOTES 9 Avoid connecting the generator to commercial

power outlet. 9 Avoid connecting the generator in parallel with any

other generator.

1 Correct 2 Incorrect

AE00091

CONNECTION

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.

WARNING

AE00086

EXTENSION CORD NOTES Extension cords should be protected by a tough flexible rubber sheath (IEC 245) or the equivalent to withstand mechanical stresses.

9 Connect the ground lead of the machine to the ground (Earth) terminal 1 and connect the end to the ground electrode buried in the ground.

WARRANTY QUESTIONS AND ANSWERS

Q. What costs are my responsibility during the warranty period?

A. The customers 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 spe- cific 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 Owners Manual instead of having the dealer do them?

A. Yes, if you are a qualified mechanic and follow the procedures specified in the Owners 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 Owners 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 Owners Manual, that failure may not be covered under 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 war- ranty 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.
