California Proposition 65

This information is important in the proper use of your machine. Failure to follow this instruction could result in damage to

your machine or property.

This i

ndicates a hazardous situation, which, if not avoided, could result in minor or moderate injury.

There is

a possibility of voiding the warranty and personal or equipment damage if instructions are not followed.

I: Safety Precautions

Please pay special attention to the following:

1. Operate the engine according to the recommendations in your owner's manual. Do not overload, overrun the engine or

run it with low load and at low speed for a long period of time.

2. Use regulated 87 octane brand of gas with no more than 10% Ethanol. The fuel should be fully deposited and filtrated

before use. Keep the fuel filler clean to prevent contamination.

3. Change the oil periodically as described in the “Maintenance” section of this manual.

4. Periodically check the installation, connection and the tightness of the mounting hardware. Tighten when necessary.

5. Periodically clean the air filter; change it as indicated in the “Maintenance” section.

6. This gasoline engine is air-cooled, so clean the cooling fins, recoil cover and air intake to allow the engine cool normally.

7. The operator should be familiar with the working principle and structure of this gasoline engine, knowing how to make an

emergency stop when needed. Do not allow anyone without training to operate the engine. Perform periodical

maintenance per the “Maintenance” section. Fix all operation problems immediately. Do not run the engine if it is not

operating properly.

8. Only operate the engine in a well-ventilated place, keep it at least one meter away from building walls or other equipment,

keep engine away from inflammables such as gasoline, matches and so on to avoid possibility of fire.

9. Refuel in a well-ventilated area with the engine stopped, do not smoke and do not allow flames or sparks in the refueling

area.

10. Do not overfill the fuel tank to avoid fuel spilling out. If there is spilled fuel around, be sure to clean it thoroughly before

starting.

11. Do not run the engine inside buildings or enclosure areas.

12. The exhaust muffler is very hot during running the engine and even after the engine stops. Never touch it, or you may get

burns. Do not transport or store the engine until it has cooled down entirely.

13. Safe warning label:

Please carefully read warning labels before operating. Generac Power Systems is not responsible if a person is hurt, or

equipment becomes damaged due to disregarding warning labels.

III: Pre-Operation Inspection

1. ENGINE OIL

SAE 10W-30 is recommended for general use. Other viscosities shown in the chart may be used

when the average temperature in your area is within the indicated range.

Oil level check

1. Remove the dipstick and clean it with a rag.

2. Reinsert the dipstick into the oil filling hole without screwing it in. Pull the dipstick out and

check oil level.

3. If the oil level is too low, add the recommended engine oil up to the oil filling neck.

4. Reinstall the dipstick.

Oil Capacity = .37 qt/11.8 oz. (0.35L)

2. AIR CLEANER

Remove the air cleaner cover and check the air filter to make sure it is clean and not damaged. Clean or replace it as necessary

(see the “Maintenance” section for maintenance of the air filter).

Use 4

-stroke engine oil, API service classification

class or equivalent. Check the API service label on the oil container to be sure

it includes the letters

SJ class or equivalent.

Oil Dipstick

Drain Plug

Oil Upper Level

Oil Lower Level

Never run the engine without

the air filter and cover installed or damage to the engine could result. Damage to the engine

by not having the air filter and cover installed is not covered under warranty

SAE Viscosity Grades

Run

ning the engine with insufficient engine oil may damage the engine severely and would not be covered under warranty.

•

Gasoline is extremely flammable and is explosive under certain conditions.

•

Only add fuel in a well-ventilation area with the engine stopped. Do not smoke and do not allow flames or sparks in the area

where gasoline is stored or where the fuel tank is refueled.

•

Do not overfill the fuel tank (there should be no fuel in the filling neck). After refueling, make sure the fuel tank cap is installed

securely.

•

Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area

cleaned up and is dry before starting the engine.

•

Avoid repeated or prolonged contact with skin or breathing of fuel vapor. Keep out of reach of children.

•

Fuel may damage paint and plastic. Be careful not to spill fuel when refueling. Any damage due to fuel spilling is not covered

under warranty.

•

It is normal to hear a "light knocking" sound when the engine is overloaded. Do not be concerned if this occurs. If "knocking"

or sounds occur at a steady speed under normal load, change the brand of gasoline; if the sounds continue, consult your

dealer for help.

•

If you continue to run the engine with a "Knocking" sound during normal operation, it will damage the engine.

•

Continuing to use the engine with "Knocking" sounds from misusing will void the engine warranty.

3. FUEL RECOMMENDATION

1. Remove the fuel tank cap and check the fuel level.

2. If the level is too low, refuel the tank to the recommended level. Remember to never fill fuel over the fuel filler shoulder.

IV. Starting the Engine

1. Turn the choke lever to the “CHOKE” position. If the engine is hot from use, leave

the choke lever in the “RUN” position.

2. Move throttle lever to the left a little.

3. Starting the engine

a. Turn the engine switch to the “ON” (START) position.

b. Pull the recoil starter grip lightly until resistance is felt, then pull briskly.

Don’t allow the

recoil starter grip to snap back against the engine. Return it gently to prevent damage to the starter

To p

revent serious injury from fire follow the kit procedures in a well-ventilated area away from ignition sources. If the engine is

hot from use, shut the engine off and wait for it to cool before proceeding.

VI. Exhaust Control System

With the engine running, carbon monoxide, nitrogen oxide and hydrocarbons are produced, and in certain conditions,

nitrogen oxide and hydrocarbon will react chemically with each other to make smoke while carbon monoxide is toxic, so

proper maintenance to control these dangers is very important.

To keep the exhaust of your engine within the standard exhaust emission, pay attention to the following:

1. Maintenance

Maintain the engine periodically in accordance with the maintenance schedule in the “Maintenance” section. The

maintenance schedule is based on normal use in normal conditions, if using under heavy load, dusty or wet circumstances or

in high temperature, service of the engine should be done more often.

2. Problems affecting exhaust emissions

•Difficult starting or difficult stopping.

•Unstable idling speed.

•Exhausting of black smoke or consuming too much fuel.

•Poor ignition, sparks or backfire.

•Premature ignition.

If you are experiencing any of above problems, contact Generac Power Systems for help.

High Altitude Kit for EPAIII Engines

3000ft to 6000ft or 6000ft to 8000ft of elevation

At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease and fuel consumption will

increase. A very rich mixture will also foul the spark plug and cause hard starting. Operation at an altitude that differs from

that at which this engine was certified, for extended periods of time, may increase emissions.

The fuel system on this Engine or Equipment may be influenced by operation at higher altitudes. Proper operation can be

ensured by installing an altitude kit when required. See the table below to determine when an altitude kit is required.

Operating this engine without the proper altitude kit installed may increase the engine’s emissions and decrease fuel

economy and performance. Kits may be obtained from Generac Power Systems, and should be installed by a qualified

individual.

Fuel Altitude Range* Kit Part Number

Gasoline

0 – 3000 ft

Not Required

3000 – 6000 ft

Altitude kit 1#

6000 – 8000 ft

Altitude kit 2#

Engine, Generator Set, Pressure Washer, Walk-Behind

Lawnmower,

Compressor, Pump, Tiller

etc.

*Elevation above sea level.

•This high altitude jet is to be used at elevations above 3000 feet.

•At elevations above 8000 feet, the engine may experience decreased performance, even with the high altitude kit.

If a carburetor is replaced, the proper high altitude kit jet will need to be installed into the replacement carburetor.

The warranty may be void if necessary adjustments are not made for high altitude use

by installing a high altitude kit.
