Effects of Altitude and Heat

The maximum output of the engine listed above is applicable to supplying electrical power for continuous service at ambient

conditions in accordance with SAE Test cord J607. The above ambient conditions are at standard sea level, with a barometric

reading of 29.92 inches and a temperature of 60 degrees fahrenheit.

Generally, the engine output power will decrease 3 1/2% for each 1000 feet of altitude above sea level, and 1% for each 10

°°

fahrenheit above the standard temperature of 60

°°

Symbols which appear throughout this manual, and will be

referenced in conjunction with Safety Message Alert

Symbols.

Engine exhaust gases contain

poisonous carbon monoxide. This gas

is colorless and odorless, and can

cause death if inhaled. NEVER operate

this equipment in a confined area or

enclosed structure that does not provide

ample free flow air.

Gasoline is extremely flammable, and

its vapors can cause an explosion if

ignited. DO NOT start the engine near

spilled fuel or combustible fluids.

DO NOT fill the fuel tank while the engine is running or

hot. DO NOT overfill tank, since spilled fuel could ignite if

it comes into contact with hot engine parts or sparks from

the ignition system. Store fuel in approved containers, in

well-ventilated areas and away from sparks and flames.

Engine components can generate extreme

heat. To prevent burns, DO NOT touch

these areas while the engine is running or

immediately after operations. Never

operate the engine with heat shields or heat

guards removed.

ALWAYS wear approved

respiratory

protection when required.
