Fuel Information; Frequently Asked Questions - Generac GP3250 Manuel Du Propriétaire

This list of Frequently Asked Questions (FAQs) are the frequently
asked questions pertaining to ALL portable models.
Some questions may not be applicable to the model covered in
this publication.

FUEL INFORMATION

Q: What is the proper fuel to use in my generator?
A: We recommend regular unleaded gasoline. Do not use E85
gasoline or mix oil with gasoline. Premium grade fuel can be
used, but is not required and will not improve performance or
output.
Q: What needs to be done to the fuel before extended storage?
A: Fuel that is not going to be used- even for short periods of
time should be treated with fuel stabilizer to slow the rate of
deterioration, gumming or varnish formation. Following the
manufacturer's recommendations, treat the quantity of fuel
remaining in the fuel tank. Open the fuel valve, start and operate
the engine for 30 minutes. Close the fuel valve and operate until
the engine stops. This circulates treated fuel through lines and
carburetor. The fuel can be drained or left in the tank.
Q: Can I convert my portable generator to run on a different fuel
besides gasoline?
A: We do not offer any type of fuel conversion kit for our portable
generators. Aftermarket conversion kits are available on the
Internet. However, if a customer decides to convert the fuel using
an aftermarket kit, the warranty is void.
Q: Can I use any type of gasoline?
A: Gasoline with an octane rating of 87, with no more than 10%
ethanol is preferred. Never use an E85 fuel or a mixture of oil
and gasoline designated for two cycle engines. Utilizing a higher
grade fuel will not yield any increase in power output.
Q: The fuel capacity in my owner's manual seems incorrect.
A: The fuel capacity listed is the total interior volume for the fuel
tank. Air space is required to allow for expansion of the gasoline
during warmer temperatures. So the actual amount of gasoline
that will fit in the tank is typically less than the stated fuel tank
capacity.
Q: How do I drain the fuel?
A: Actually, treating the fuel for storage is a better option. The treated
fuel can then be left in the tank. Fuel can be removed through
the fill opening using an automotive style siphon. Exercise all
appropriate cautions when handling fuel.

Frequently Asked Questions

MAINTENANCE & OIL INFORMATION
Q: I am out of the recommended oil, but I need to operate my
generator. What are my options?
A: In an emergency, oil with an API rating of SH, SJ, SK, CF-4,
ILSAC, GF-1, GF-2 or GF-4 can be used. It can be mineral,
semi-synthetic or synthetic. Any of the following viscosities are
permissible: SAE 5W-30, 10W-30, 10W-40, 20W-50, 30 or 40
weight. Change the oil as soon as possible using Generac oil, per
the owner's manual recommendations.
Q: If no dipstick is included on my model's engine. How do I
know when I have put enough oil in my portable generator?
A: The customer should fill the oil to the bottom of the cap's threads
on the crankcase. The oil should always be checked and filled
when your engine has cooled completely.
Q: Should I screw the oil cap/ dipstick all the way down when
checking the oil level?
A: When checking the oil, the oil fill cap/ dipstick should be screwed
in all the way. The oil level should be checked and filled when the
engine has cooled completely.
Q: The manual says the oil capacity is 1.7 quarts. When I add 1.7
quarts, it doesn't reach the threads on the crankcase.
A: Add enough oil to reach the bottom of the threads on the
crankcase, even if it is more than the manual recommends.
OPERATION
Q: The hourmeter said it was time to service the air filter. After
the service has been performed, does anything need to be
done to the hourmeter?
A: The hourmeter will alert the owner continuously for one hour
before and until one hour after scheduled maintenance has
been reached. This includes oil changes (at 100 hours) or air
filter service (at 200 hours). As hours of operation continue
to accumulate, the hourmeter will automatically reset itself
until the next 100 or 200 hour service interval is reached. See
the Hourmeter section of your owner's manual for additional
information. The hourmeter on some generator models have
a reset button that allows the operator to move between
maintenance intervals and reset intervals by holding the reset
button for nine seconds. NOTE: Not all generator models have
the reset button.
Q: How do I adjust the valve clearance?
A: Valve clearance adjustment is critical to proper engine operation
and requires special tools and training. Instructions are covered in
the Valve Clearance Adjustment section of your owner's manual.
However, if you are uncomfortable performing this service
procedure, have your dealer maintain the generator's valve
clearance at the intervals specified.
