GENERAL INFORMATION

Gasoline
IMPCO recommends the use of name brand
high detergent gasoline. Gasoline is a mixture
of many different hydrocarbons, including ole-
fins, which are heavy, waxy compounds. Over
time, these deposits can build up and clog the
fuel injectors. The formation of these deposits
is a normal consequence of engine operation,
so detergents are added to high quality gaso-
line to help keep the injectors clean. The use
of low quality low detergent gasoline may
cause fuel injectors to fail. Fuel injector re-
placement or cleaning is expensive, and the
cleaning procedure requires special equip-
ment that may not be practical in the industrial
lift truck market. Speak with your fuel supplier
to verify that the fuel you are supplied con-
tains the necessary fuel additives to keep
your fuel system clean. IMPCO may deny
emissions related warranty claims due to the
use of low quality low detergent gasoline.
FUEL SYSTEM CAUTIONS
Do not smoke, carry lighted tobacco or
use a lighted flame of any type when
working on or near any fuel related
component. Highly flammable air-fuel
mixtures may be present and can be
ignited causing personal injury
Do not allow LPG to contact the skin.
LPG is stored in the fuel tank as a liq-
uid. When LPG contacts the
atmosphere, it immediately expands
into a gas, resulting in a refrigeration
effect that can cause severe burns to
the skin.
Do not allow LPG to accumulate in
areas below ground level such as in a
service pit or underground ventilation
systems. LPG is heavier than air and
can displace oxygen, creating a dan-
gerous condition
Do not make repairs to the LPG fuel
system if you are not familiar with or
trained to service LPG fuel system.
Contact the dealer who sold you the
vehicle to locate a repair facility with
trained technicians to repair your fuel
system
