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 sure to bring your warranty registration identification or other valid proof of the original date of purchase. If a question or problem arises regarding warranty, first contact the owner of the dealership. Since all warranty matters are handled at the dealer level, this person is in the best position to help you. If you are still not satisfied and require additional assistance, please write:

This list is compiled from the purchase registrations sent to Yamaha Motor Corporation, U.S.A. by the selling dealer at the 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:

YAMAHA MOTOR CORPORATION, U.S.A.

FUEL IS HIGHLY FLAMMABLE AND POISONOUS

9 Always turn off the engine when refuelling. 9 Never refuel while smoking or in the vicinity of an

open flame.

9 Take care not to spill any fuel on the engine or

muffler when refuelling.

9 If you swallow any fuel, inhale fuel vapor, or allow

any to get in your eye(s), see your doctor immediately. If any fuel spills on your skin or clothing, immediately wash with soap and water and change your clothes.

9 When operating or transporting the machine, be

sure it is kept upright. If it tilts, fuel may leak from the carburetor or fuel tank.

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 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.

OIL WARNING SYSTEM

When the oil level falls below the lower level, the engine stops automatically. Unless you refill with oil, the engine will not start again.

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 engine oil is insufficient. Add oil and restart.

G.F.C.I. RECEPTACLE (for YG2600)

The G.F.C.I. (Ground Fault Circuit Interrupter) 1 shuts off power to the protected receptacles if a ground fault (electrical leak) is detected. If the reset button 2 pops out 3, the equipment plugged into the receptacle may be faulty. If this hap-

pens, check the equipment carefully. If the equipment appears to be in good condition, press the reset button firmly until a click is heard. This will restore power. If the reset button pops out again, unplug the equipment immediately. Have the equipment inspected and repaired by a qualified repairperson before attempting

763-060

to use it again.

TO REDUCE THE CHANCE OF ELECTRICAL SHOCK:

9 Do not attempt to operate equipment if the

ground fault circuit interrupter reset button pops out repeatedly during use.

9 Test the ground fault circuit interrupter during

the pre-operation checks according to the maintenance instructions on page 25.

9 Remember that only receptacles labeled

“Ground Fault Protected” have ground fault circuit interrupter protection.

PRE-OPERATION CHECK

NOTE:

Pre-operation checks should be made each time the generator is used.

Do not wring out the element. This could cause it to tear.

4. Insert the element into the air filter.

NOTE:

Be sure the element sealing surface matches the air filter so there is no air leak.

The engine should never run without the element; excessive piston and cylinder wear may result.

Never use solvent while smoking or in the vicinity of an open flame.

STORAGE

Long term storage of your machine will require some preventive procedures to guard against deterioration.

AE00611

DRAIN THE FUEL

1. Drain the fuel tank, fuel cock, and carburetor float bowl.

a Carburetor drain plug

2. Pour a cup of SAE 10W30 or 20W40 motor oil into the tank.

3. Shake the tank to coat the inner surfaces thoroughly.

4. Drain off the excess oil.

AE00621

ENGINE

1. Remove the spark plug, pour about one tablespoon of SAE 10W30 or 20W40 motor oil into the spark plug hole and reinstall the spark plug. Recoil start the engine by turning over several times (with ignition off) to coat the cylinder walls with oil.

2. Pull the recoil starter until you feel compression. Then stop pulling. (This prevents the cylinder and valves from rusting).

3. Clean exterior of the generator and apply a rust inhibitor.

4. Store the generator in a dry, well-ventilated place, with the cover placed over it.

5. The generator must remain in a vertical position when stored, carried or operated.
