SAFETY INFORMATION

AE00072

Exhaust fumes are poisonous 9 Never operate the engine in a closed area or it may

cause unconsciousness and death within a short time. Operate the engine in a well ventilated area.

AE00075

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 muf- fler when refueling.

9 If you swallow any fuel, inhale fuel vapor, or allow any to get in your eye(s), see your doctor immedi- ately. 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 generator, be sure it is kept upright. If it tilts, fuel may leak from the carburetor or fuel tank.

AE00843

Engine and muffler may be hot 9 Place the generator in a place where pedestrians

or children are not likely to touch the generator.

9 Avoid placing any flammable materials near the exhaust outlet during operation.

9 Do not operate the engine with a dust cover or other objects covering it.

9 When covering the generator, be sure to do so only after the engine and muffler have completely cooled down.

9 Be sure to carry the generator only by its carrying handles.

9 Do not place any obstacles on the generator.

AE00083

Electric shock prevention 9 Never operate the engine in rain or snow.

9 Never touch the generator with wet hands or elec- trical shock will occur.

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 generator to the ground (earth) terminal and connect the end to the ground electrode buried in the ground.

DANGER Using a generator indoors CAN KILL YOU IN MINUTES.

Generator exhaust contains carbon monoxide. This is a poison you cannot see or smell.

NEVER use inside a home or garage, EVEN IF doors and windows are open.

Only use OUTSIDE and far away from windows, door, and vents.

PREPARATION AE00856

Fuel

9 Fuel is highly flammable and poisonous. Check SAFETY INFORMATION (See page 1) careful- ly before filling.

9 Do not overfill the fuel tank, otherwise it may overflow when the fuel warms up and expands.

9 After fill the fuel, make sure the fuel tank cap is tightened securely.

9 Immediately wipe off spilled fuel with a clean, dry, soft cloth, since fuel may deteriorate paint- ed surfaces or plastic parts.

9 Use only unleaded gasoline. The use of leaded gasoline will cause severe damage to internal engine parts.

NOTICE

WARNING

Remove the fuel tank cap and fill the fuel into the tank up to the bottom edge of the fuel filter. The fuel level in the fuel tank can be checked through the fuel level gauge.

1 Fuel level gauge 2 Fuel level 3 Fuel filter

Your Yamaha engine has been designed to use regular unleaded gasoline with a pump octane number ((R + M)/2) of 86 or higher, or research octane number of 91 or higher.

PRE-OPERATION CHECK

If any item in the Pre-operation check is not work- ing properly, have it inspected and repaired before operating the generator.

The condition of a generator is the owners responsibil- ity. Vital components can start to deteriorate quickly and unexpectedly, even if the generator unused.

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

Pre-operation check Fuel (See page 9) 9 Check fuel level in fuel tank. 9 Refuel if necessary.

Fuel line 9 Check fuel hose for crack or damage. 9 Replace if necessary.

Engine oil (See page 10) 9 Check oil level in engine. 9 If necessary, add recommended oil to specified

level. 9 Check generator for oil leakage.

The point where abnormality was recognized by use 9 Check operation. 9 If necessary, consult a Yamaha dealer.

Application range When using the generator, make sure the total load is within rated output of a generator. Otherwise, generator damage may occur.

TIP 9 means below. 9 Application wattage indicates when each device is used by itself.

9 Do not overload. The total load of all electrical appliances must not exceed the supply range of the generator. Overloading will damage the generator.

9 Some types of precision equipment such as electronic controllers, PCs, elec- tronic computers, microcomputer-based equipment and battery chargers are sensitive to voltage fluctuations and may require more stable voltage supply than the voltage supplied from the portable generator. When using such equipment, consult with a Yamaha dealer.

9 When supplying precision equipment, electronic controllers, PCs, electronic computers, microcomputerbased equipment or battery chargers, keep the gen- erator a sufficient distance away to prevent electrical interference from the engine. Also ensure that electrical noise from the engine does not interfere with any other electrical devices located near the generator.

9 If the generator is to supply medical equipment, advice should first be obtained from the manufacturer, a medical professional or hospital.

9 Some electrical appliances or general-purpose electric motors have high start- ing currents, and cannot therefore be used, even if they lie within the supply ranges given in the above table. Consult the equipment manufacturer for fur- ther advice.

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.

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 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.
