Installation

LOCATING

Locate the engine at least 1 meter (3.0 ft) away from buildings or other structures. Provide proper exhaust routing. Refer to EXHAUST SYS- TEM below. Do not use the engine near flammables or other hazard- ous materials such as trash, rags, lubricants, or explosives.

When determining the mounting location, make sure of the following:

• Gas and oil can easily be checked and supplied

carburetor.

If the tank is mounted above the carburetor, a fuel shut-off valve must be connected between the fuel tank and the fuel pump.

Note: To prevent fuel from flooding the carburetor, the fuel valve must be closed when the engine is not running.

Properly install fuel lines to the carburetor bycompletely inserting the hose onto the fitting and then secure it with a hose clamp.

• Oil can be changed.

•

The air cleaner can be serviced

•

Spark plugs can be checked.

Carefully examine the engines position, the method of connecting it to a machine, and the foundation and support structure.

Locate the engine in a safe area on a stable level surface free of small rock, loose gravel, etc.

! CAUTION Operating the engine on an incline may cause seizure due to improper lubrication; even at maximum oil level.

! WARNING

Gaseous fuels are flammable and explosive and can cause severe personal injury or death.

Do not smoke if you smell gas or are near fuel tanks or fuel-buring equipment or are in an area sharing ventilation with such equipment. Keep flames, sparks, pilot lights, electrical switches, arc-producing equipment and all other sources of ignition well away. Keep a type ABC fire extinguisher handy.

EXHAUST SYSTEM

EXHAUST GAS IS DEADLY! Engine-powered equipment must never be operated inside buildings or other enclosed spaces.

If a long exhaust pipe is used, the internal resistance results in loss of engine power. The exhaust pipe ID must increase in proportion to exhaust pipe length. For example, if the exhaust pipe is:

less than 3.0 m (9.8 ft.) long - pipe ID = 30mm (1-3/16in) less than 5.0 m (16.4 ft)long - pipe ID = 33mm (1.3in)

It is the responsibility of the equipment operator(s) to check for exhaust leaks on a daily basis and to have all leaks repaired before continuing to operate the equipment.

FUEL

Fuel Tank

The fuel tank system must be provided by the OEM. A fuel

shut-off valve must connected between the fuel line and the fuel pump.

The fuel tank may be mounted up to 0.66 meters (2.0ft) below the

Do not refill the fuel tank while the engine is running. Do not overfill the tank.

Wipe away any spilled fuel and wait until it has dried before starting the engine.

Fuel recommendations

Use clean, fresh unleaded gasoline having a minimum octane rat- ing (Anti-Knock Index) of 87. This engine is certified to operate on unleaded gasoline.

During some periods of the year only mandated “oxygenated” gaso- lines may be available. These are acceptable for use, but not prefer- able. Do not use gasoline or gasoline additives (de-icers) containing methanol because methanol can be corrosive to fuel system compo- nents.

! CAUTION Do not use gasoline or gasoline additives containing methanol because methanol can be corrosive to fuel system components.
