9. TROUBLESHOOTING<br />
ENGINE DOES NOT START<br />
TROUBLESHOOTING / TECHNICAL INFORMATION<br />
Possible cause Remedy<br />
Check position of operating elements Fuel valve to OFF Set fuel valve to ON<br />
Choke lever to OPEN Turn the lever to CLOSED until the engine<br />
is warm.<br />
Ignition switch OFF Turn switch to ON<br />
Check the gasoline No gasoline Fuel up<br />
Poor quality gasoline; engine stored without<br />
gasoline being treated or drained or refuelled<br />
with poor quality gasoline<br />
Remove and inspect spark plugs Spark plugs faulty, corroded or wrong<br />
electrode gap.<br />
Other errors<br />
Consult the operating instructions or bring the<br />
engine to a licensed dealer.<br />
INSUFFICIENT ENGINE POWER<br />
Spark plugs filled with gasoline (engine<br />
“flooded”)<br />
Fuel filter clogged, carburettor defective,<br />
ignition fault, valve jammed, etc.<br />
Drain gasoline tank and carburettor. Refuel<br />
with new gasoline.<br />
Adjust electrode gap or replace spark<br />
plugs.<br />
Dry and reinstall spark plugs. Start engine<br />
with throttle lever in FAST position.<br />
Replace or repair faulty components.<br />
Check air filter. Filter elements clogged. Clean or replace filter elements.<br />
Check the gasoline No gasoline Fuel up<br />
Other errors<br />
Consult the operating instructions or bring the<br />
engine to a licensed dealer.<br />
10. TECHNICAL INFORMATION<br />
TECHNICAL INFORMATION<br />
ETHANOL<br />
(Ethyl alcohol or grain alcohol) 10% of the volume<br />
You can use gasoline with up to 10% of ethanol mixed in.<br />
Gasoline grades containing ethanol are sometimes marketed<br />
under the name ”Gasohole“.<br />
MTBE<br />
(methyl tertiary butyl ether) 15% of the volume<br />
You can use gasoline grades containing up to 15% of MTBE.<br />
METHANOL<br />
(Methyl alcohol or wood spirit) 5% of the volume<br />
You can use gasoline grades containing up to 5% of methanol as<br />
long as this gasoline contains additional solvents and an<br />
anticorrosive to protect the fuel system. Gasoline grades with<br />
more than 5% of methanol may cause problems during starting<br />
and/or with the engine power. Furthermore, they may damage<br />
Poor quality gasoline; engine stored without<br />
gasoline being treated or drained or filled with<br />
poor quality gasoline.<br />
Fuel filter clogged, carburettor defective,<br />
ignition fault, valve jammed, etc.<br />
Drain gasoline tank and carburettor. Refuel<br />
with new gasoline.<br />
Replace or repair faulty components.<br />
metal, rubber and plastic parts of the fuel system.<br />
If you notice undesirable symptoms during operation change the<br />
petrol station or use a different grade of gasoline.<br />
Damages on the fuel system or problems with the motor<br />
performance that can be traced to gasoline grades used and<br />
where the percentages listed above were exceeded are not<br />
covered by the warranty.<br />
Information on the emission control system<br />
Cause for pollutant emissions<br />
Carbon monoxide, nitrogen oxide and hydrocarbons are<br />
generated through the combustion process. Controlling<br />
hydrocarbons and nitrogen oxides is important because under<br />
certain circumstances they react chemically and change into<br />
photochemical smog through the effect of the sun. Although<br />
carbon monoxide does not react in the same manner, it is still<br />
toxic.<br />
