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:

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:

AE00091

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.

e

If the reset button 2 pops out 3, the equipment plugged into the receptacle may be faulty. If this happens, 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

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 35.

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.

å EF4000DE/EF5200DE/YG4000D/YG5200D ∫ EF6600DE/YG6600D/YG6600DE

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.

BATTERY (for EF4000DE/EF5200DE/EF6600DE/YG6600DE)

1. Remove the battery.

2. Check the fluid level. Add only distilled water if necessary. (See page 34; “BATTERYReplenishing the battery fluid”)

3. After checking the fluid level, charge the battery.

4. Store the battery in a cool, dark and dry place and charge it once a month.

Do not store the battery in an excessively warm or cold place [i.e., less than 0°C (30°F) or more than 30°C (90°F)].

w

9 Disconnect the negative lead first, then the

positive lead from the battery.

9 Connect the positive lead first, then the nega-

tive lead to the battery when installing the battery.

9 Never smoke or make and break connections

at the battery while charging. Sparks may ignite the battery gas.

9 Be sure the battery terminals are tight and that

the battery vent tube is properly routed and is securely attached to the battery.

cC

9 Do not disconnect the battery during engine

operation.

9 Avoid operating the generator with the battery

removed.

AE00632

RECOMMENDED BATTERY (for EF4000DE/EF5200DE/EF6600DE/YG6600DE)

Recommended battery:

Capacity: 12V/26A•h

NOTE:

9 Clamp the red wire to the positive (+) terminal and

the black wire to the negative (–) terminal of the battery. Do not reverse these positions.

9 Be sure the battery is installed on the battery

mount tray securely.
