TECHNICAL INFORMATION
ETHANOL
(Ethyl alcohol or grain alcohol) 10% of the volume
You can use gasoline with up to 10% of ethanol mixed in.
Gasoline grades containing ethanol are sometimes marketed
under the name "Gasohole".
MTBE
(methyl tertiary butyl ether) 15% of the volume
You can use gasoline grades containing up to 15% of MTBE.
METHANOL
(Methyl alcohol or wood spirit) 5% of the volume
You can use gasoline grades containing up to 5% of methanol as
long as this gasoline contains additional solvents and an
anticorrosive to protect the fuel system. Gasoline grades with
more than 5% of methanol may cause problems during starting
and/or with the engine power. Furthermore, they may damage

Information on the emission control system
Cause for pollutant emissions
Carbon monoxide, nitrogen oxide and hydrocarbons are
generated through the combustion process. Controlling
hydrocarbons and nitrogen oxides is important because under
certain circumstances they react chemically and change into
photochemical smog through the effect of the sun. Although
carbon monoxide does not react in the same manner, it is still
toxic.
Remedy
Set fuel valve to ON
Turn the lever to CLOSED until the engine
is warm.
Turn switch to ON
Fuel up
Drain gasoline tank and carburettor. Refuel
with new gasoline.
Adjust electrode gap or replace spark
plugs.
Dry and reinstall spark plugs. Start engine
with throttle lever in FAST position.
Replace or repair faulty components.
Clean or replace filter elements.
Fuel up
Drain gasoline tank and carburettor. Refuel
with new gasoline.
Replace or repair faulty components.
