n) Starting the engine
When operating the new engine, a certain run-in time has to be observed. During the run-in time, the engine parts adjust to one another, which
leads to maximum performance and prevents premature wear.
The run-in procedure must be carried out very carefully!
Please note the individual operating instructions of the combustion engine!
Preparations
• The carburettor is already roughly pre-adjusted.
• Before operating the engine, clean it with compressed air.
This way you make sure that the combustion chamber is free of dirt which could get into the engine through the plug socket.
• Insert a glow plug with an average or a cold heat range (depending on the fuel).
• Oil the air filter slightly in order to filter out even fine dust particles.
• Insert the glow plug.
• Open the tank cap and fill in the fuel.
Starting the engine
The wheels must be hanging freely in the air! Put the model
on a suitable car stand or similar support.
• 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
pull-start cable by pulling it out slowly 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 pull-start - 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 screw the main jet needle anti-clockwise by 3 revolutions.
• Try to start the engine again.
If the engine does not start running after the 10th attempt, repeat the procedure described above or try to solve the problem according to the troubleshooting
table!
