the chassis. Consult the generator operating instruc-
tions for special cautions about maintenance with differ-
ent types of fuels.
Fuel Fill
The fuel filler cap is located toward the rear olthe coach.
Modem fuel systems may build up vapor pressure within
, the tank as the gasoline warms during use or hot
weather. Under certain conditions, 'sudden release of
this pressure when removing the gasoline
cap
can
cause gasoline to spray from the fill opening, creating a
fire hazard.
WARNING
WHEN REMOVING THE GASOLINE 'CAP,
ROTATE SLOWLY ONLY FAR ENOUGH TO
ALLOW PRESSURE TO RELEASE. AFTER
"HISSING"SOUND STOPS, COMPLETE
THE REMOVAL OF THE CAP.
To protect the gasoline system from excessive pressure
or vacuum, or from sudden release of pressure, replace
lost caps with caps of the same deSign Which are
aVailable from ypur ,Fleetwood motor home,dealer.
" " Clean up fuel spills immediately. Raw fuel spilled on the
motor home could damage the exterior finish, and is a
serious fire hazard.
• FueLTypesAnd ,Vapor Lock
, Today's automotive fuel and emissions systems are
sophisticated and highly engineered to meet Federal
and State emissions standards. They are also some-
times sensitive to fuel types and blends, particularly
fuels blended for certain altitudes and climates. Fuel
suppliers provide customers with 'the 'correct fuel for
their location· 'and seasonal condltlons;"'Sometimes,
though, fuel blended forwinter Is supplied during sum-
mer months. ' '
~Vapor lock" occurs when gasoline vaporizes, and
vapor pockets block the flow of liquid fuel to the engine.
If you experience engine stail or stutter, you may be
experiencing ,vapor lock.
If your engine and fuel system are properly tuned and
maintained, you should not experience this problem. If
vapor lock occurs, the fuel Itself could be the cause. If at
ail possible; check with the service station operator as to
, the fuel blend before filling your fuel tank, If you pur-
chase your fuel from nationally recognized fuel dealers,
your chances of vapor lock can be redUced. If you store
your motor home during the winter months, be aware
that when you take the vehicle out of storage in the
spring or summer, winter fuel may cause vapor lock until
it is consumed.

GENERAL CHASSIS TOPICS
Variable Speed Engine Fan,
When the engine is under load or requires maximum
cooling, the engine fan adjusts and turns faster. The fan
may become very noisy at high speed and when maxi-
mum cooling is required. High speed fan noise can
, sometimes be, misinterpreted as transmission Slippage.
, ,This
i~no.t:the
case. High
engi~
speed and tempera-
, ture, ccmdltions, such as pulling away, from a stop after
long freeway driving, can cause loud fan noise until the
engine cools down. This fan noise indicates that the fan
, Is doing what it is supposed to do. This noise is not a
defect In \he, fan pr the transmission.
Exhaust System Heat
Your motor home engine has been designed to conform
to Federal and State emission requirements. To meet
these requirements, engine operating temperatures are
high.
As
a resul!, the engine and exhaust systems
radiate a great deal of heat.
Special heat shields are built Into your motor home to
protect wiring and other components from possible tieat
damage caused by the exhaust system. Do not remove
•
it~eseshields;
modlfy;tl)e exhaust system, or add addi-
tional equipment, such as wiring, plumbing, or other
components, which will be affected by exhaust system
heat. " ,
CARBON MONOXIDE
SAFETY PRECAUTIONS
Carbon monoxide Is a coloriess, tasteless, odoriess
gas. I! Is a by-product of combustion in engines. The
engines in your motor home and generator system
produce I! constantly while they lire running. CARBON
, MONOXIDE'IS DEADLY. Pleasiiread,and understand
the following precautions to protect yourself and others
from the effects of carbon monoxide poisoning.
WARNING
EXHAUST GASES ARE DEADLY. DO NOT
BLOCK ,THE TAILPIPES OR SITUATE THE
VEHlqLE INA PLACE WHERE THE EX-
HAUST GASES HAVE ANY POSSIBILITY OF
ACCUMULATING EITHER, OUTSIDE, UN-
QERNEATH, OR INSIDE YOUR VEHICLE OR
ANY NEARBY VEHICLES.' OUTSIDE AIR
MOVEMENTS CAN CARRY EXHAUST
GASES INSIDE THE VEHICLE THROUGH
WINDOWS OR OTHER OPENINGS REMOTE
FROM THE EXHAUST OutLET. OPERATE
THE ENGINE(S) ONLY WHEN SAFE DIS-
PERSION OF EXHAUST GASES CAN BE
