SPECIFICATIONS
FUEL REQUIREMENTS
(GASOLINE UNITS)
These generators are equipped with gasoline fuel
systems as standard equipment. Specific installa­
tions may provide either a separate fuel tank for the
generator, or the generator may “share” the vehicle
engine’s fuel tank.
NOTE; Installations using a “shared" fuel tank may
have a generator fuel pickup tube that is shorter than
the vehicle engine’s pickup tube. Such an arrange­
ment causes the generator engine to “run out of gas”
while adequate fuel for the vehicle remains in the
tank.
To reduce lead and carbon deposits use high quality
UNLEADED gasoline with the generator. Leaded
REGULAR grade gasoline is an acceptable substi­
tute.
NOTE: Using “Unleaded” gasoline contributes to
longer engine valve life by reducing lead and carbon
deposits.
CAUTION: Generac does not recommend using
any gasoline containing alcohol, it must not con­
tain more than 10 percent ethanol and it must be
removed from the generator during storage. Do
NOT use any gasoline containing methanol. If you
use gasoline viiith alcohol, inspect more frequently
for fuel leaks and other abnormalities.
FUEL REQUIREMENTS (LP UNITS)
These generators are equipped with a liquefied petro­
leum (LP) gas fuel system. LP gas is usually supplied
as a liquid in pressure tanks.
These generators require a “vapor withdrawal” type
fuel system. This type of gaseous fuel system uses
the vapors forming above the liquid fuel in the storage
tank. Air temperature around the storage tank must
be high enough to sustain adequate fuel vaporization.
In colder climates, you may need to use an indepen­
dent heat source to be sure the fuel sufficiently vapor­
izes in the storage tank.
LP gas may consist of propane, butane or a mixture
of the two gases. Propane vaporizes at temperatures
as low as -20°F (-29°C), but butane returns to its liq­
uid state when the temperature drops below about
32°F (0°C). For that reason, a higher ratio of propane
is desired in the gas mixture when temperatures drop
below freezing.
FUEL CONSUMPTION (IN GALLONS PER HOUR):
LOAD GASOLINE LP
NO 0.13 0.37
HALF 0.20 0.52
FULL 0.40 1.05
ENGINE OIL REQUIREMENTS
The recommended oils include the following:
• During summer months: SAE 30. An acceptable substi­
tute is SAE 10W-30.
• During winter months: SAE 5W30. DO NOT USE SAE
10W-40.
Crankcase and oil filter capacity is about 950ml or
one
(1) quart. Use no special additives. See
“Maintenance” section for oil level check and fill pro­
cedures.
