PRIMEPAa 55C and 55LP Recreational Vehicle Generators
1.6 SPECIFICATIONS
♦ 1.6.1 FUEL REQUIREMENTS
This generator is equipped with a gasoline fuel system
as standard equipment. Specific installations may pro­
vide either a separate fuel tank for the generator, or the
generator may “share” the vehicle engine’s fuel tank.
NOTE
Some 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
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.
NOTE:
Using imleaded gasoline contributes to longer engine
valve life by reducing lead and carbon deposits.
------ Jk CAUTION Jk-----------
A
Generac does not recommend using any
gasoline containing alcohol (such as "gasohol").
If you use any gasoline containing alcohol, it
must not contain 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 with
alcohol, inspect more frequently for fuel leaks
and other abnormalities.
♦ 1.6.2 ENGINE OIL REQUIREMENTS_______________
Use only high quality detergent oil classified “For
Service SF” and with an oil viscosity rating of SAE
lOW-30 oil. Do not pour in any additives to the rec­
ommended oil. Engine crankcase capacity is 1.4
liters. See Section 3.2 on page 11 for oil level check
and filing procedures.
