Starting the engine
The wheels must be hanging freely in the air! Put the model on a suitable car stand or similar.
• Pull out the pull start cable slowly several times to let the carburettor ingest fuel.
• Repeat the procedure until there are no more air bubbles in the fuel tube and the fuel is just about to enter the carburettor.
Caution!
Do not pull out the cable all the way. Always pull it out to a maximum of 3/4 of its length! Determine the length of the cable by slowly pulling it
out without ignition!
Never apply force when pulling it out!
• Put the glow plug starter with a fully charged starter battery on the glow plug. Make sure it sits tightly!
• Now swiftly pull out the cable until the engine starts. Hold the model firmly with your other hand.
Never touch the drive mechanism as it could start running if the slipping clutch engages. Risk
of injury!
• When the engine is running, let go of the cable and remove the glow plug starter.
Only connect the glow plug starter to the engine for a short time. Otherwise the glow plug can
burn out prematurely.
• If the pullstart - after several unsuccessful attempts - only works with increased effort, too much fuel has reached the combustion chamber and the crankcase.
The engine has been flooded.
Refrain from further start attempts and remove the excess fuel in order to prevent damage to the pull starter or the engine!
For this purpose, proceed as follows:
• Carefully screw in the main jet needle clockwise all the way.
• Unscrew the glow plug and check its glow function.
• Place a piece of cloth on the engine and pull out the pull starter 5-6 times (3/4 of its length!): The fuel is pumped out and evaporates.
• Insert the glow plug again.
• Now unscrew the main jet needle by turning it 3 revolutions anti-clockwise.
• Try to start the engine again.
If the engine will not start running after the 10th attempt, repeat the procedure described above or try to solve the problem according to the troubleshooting
table!
Switching off the engine
Cut off the air supply to the carburettor. For this purpose, proceed as follows:
• Close the exhaust pipe with a motor stopper (or use a cloth instead) or stop the flywheel of the engine on the underside of the chassis using protective gloves.
The fuel supply must not be disconnected as otherwise the engine might overheat.
