Specifications - Generac Power Systems 004703-1 Owner's Manual

General Information
2. 120/240 VAC loads — one load with a maximum total watt-
age requirement equal to the generator's rated power output,
and 240V across the generator output terminals; or two sep-
erate loads, each with a maximum total wattage requirement
equal to half of the generator's rated power output (in watts),
and 120V across the generator output terminals. Figure 1.2,
shows the generator lead wire connections for 120/240 VAC
loads. Also refer to the "Line Breakers" section for circuit
breaker ratings.
This procedure should be done by an Authorized Service Dealer or
other qualified installer.

SPECIFICATIONS

1.6.1 FUEL REQUIREMENTS
This generator is equipped with a gasoline or LP fuel system.
Specific installations may provide either a separate fuel tank for
the generator, or the generator may "share" the vehicle engine's
fuel tank.
Gasoline Fuel Consumption (gph)
Model 10% Load
QuietPact 75G 0.51
Some installations using a "shared" fuel tank may have a gen-
erator fuel pickup tube that is shorter than the vehicle engine's
pickup tube. Such an arrangement 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 substitute.
Using unleaded gasoline contributes to longer engine valve life
by reducing lead and carbon deposits.

NOTE
NOTE:
The manufacturer does not recommend using
any gasoline containing alcohol (such as
"gasohol"). If using any gasoline containing
alcohol, it must not contain more than 10 per-
cent ethanol, and it must be removed from the
generator during storage. Do NOT use any
gasoline containing methanol. If using gasoline
with alcohol, inspect more frequently for fuel
leaks and other abnormalities.
LP Fuel Consumption (lb./hour)
The LP powered range of generators are fitted with a nonadjust-
able, factory set system. These systems are tamper-proof to meet
1997 California Air Resources Board requirements for engine
emission.

1.6.2 ENGINE OIL REQUIREMENTS
Use only high quality detergent oil rated with American Petroleum
Institued (API) Classification SF, SG, SH or SJ. The recommended
oil viscosity weights include the following:
• During summer months (40 deg. F and higher), SAE 30 or SAE
10W-30
• During winter months (40 deg. F to -20 deg. F), SAE 5W-30 or
SAE5W20
• DO NOT USE SAE 10W-40
Crankcase and oil filter capacity is approximately 1.8 L or 1.9 U.S.
quarts. DO NOT use special additives. See sections "Checking the
Engine Oil Level" and "Changing the Engine Oil and/or Oil Filter" for
oil level check and filling procedures.
