TECHNICAL INFORMATION
Position of serial number
Enter the serial number at the location provided below. You will
need this serial number to order parts and with technical or
warranty-related queries.
Engine serial number:
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
metal, rubber and plastic parts of the fuel system.
If you notice undesirable symptoms during operation change the
petrol station or use a different grade of gasoline.
Damages on the fuel system or problems with the motor
performance that can be traced to gasoline grades used and
where the percentages listed above were exceeded are not
covered by the warranty.
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.
The so-called ”lean“ adjustment of carburettors and other
systems utilizes this fact to reduce the emission of carbon
monoxide, nitrogen oxide and hydrocarbons.
Impermissible interventions and modifications
Interventions or modifications to the emission control system may
cause the values to rise above the legal limits. These
interventions include, amongst others:
z
Removal or modifications of the supply, fuel or exhaust
systems.
z
Modification or disconnection of the controller or the speed
adjustment to allow the engine to be operated with other
performance ranges than specified by the manufacturer.
Problems that may affect the emission of pollutants
You should have the engine inspected or repaired by your
customer service if you notice the following problems:
z
Difficult starting or stalling after starting
z
Irregular idle
z
Misfiring under load
z
Afterburning (exhaust backfiring)
z
Black exhaust gases or high gasoline consumption.
Spare parts
The emission control systems of your engine correspond with the
manufacturer specifications. We absolutely recommend the use
of original spare parts during maintenance. These original spare
parts are manufactured according to the same standards as
original parts, that is, you can rely on their performance. The use
of non-original spare parts and compromised quality may affect
the efficiency of the emission control system.
The manufacturer of such accessory parts is responsible to
ensure that the respective part does not have a negative effect
on emissions. The manufacturer of such a part must confirm that
the use of the spare part does not cause the engine to be unable
to meet the pollutant regulations.
Maintenance
Please follow the maintenance plan. Remember that this plan
was developed assuming that you will use your engine according
to the specifications. Continuous operation under full load or the
use in wet or dusty conditions requires more frequent
maintenance.
