=== Break-in Procedure ===
{{Note|type=info|text='''Note:''' The KAVAN AP06 engine does not use a ring to seal the combustion chamber. The cylinder sleeve is tapered at the top, causing severe resistance when the piston moves through the top of the stroke. This is normal. When the engine heats up to operating temperature and begins to break-in, this resistance will decrease and the proper piston and cylinder clearance will be achieved. Do not in any way disassemble the engine and try to modify the piston and cylinder fit. This will void any and all warranties. The break-in procedure will guide you through the steps necessary to properly break-in your new KAVAN AP06 engine. Please follow the steps closely.}} The break-in process allows the engine parts to perfectly fit to each other and properly protect each part from premature wear. The engine should be broken in using a fuel that contains no more than 15% nitromethane and no less than 20% Castor Oil lubricant. Synthetic lubricant fuels should not be used during the break-in procedure. For the break-in procedure we recommend mounting the engine into the airplane it will be used in. This way the muffler, fuel tank and throttle linkage can all be tested in combination with the engine. If your airplane uses a cowling, it should be removed during the break-in procedure.
# Install a 5.7 x 3 propeller onto the engine.
# Turn the high speed needle valve out 2-1/2 turns from the fully closed position.
# If you are using an electric starter to start the engine, follow the procedure in the previous section. If you are starting the engine by hand, follow that procedure in the previous section.
# Open the throttle barrel to approximately 1/4 throttle. Connect the glow starter to the glow plug. If you are using a glow starter connected to a power panel, turn the amperage adjustment knob until the meter reads between 3 and 4 amps. Start the engine using an electric starter or by hand. If starting by hand you will need to vigorously flip the propeller through the compression stroke several times before the engine will start.
# Once the engine starts, open the throttle barrel to about 1/2 throttle and immediately turn the high speed needle valve in (lean) until the engine runs without cutting out. The exhaust should be very noticeable from the muffler and the engine should sound like it is running very rough. This is a good “rich” mixture setting.
# After the engine has been running for about 1 minute, remove the glow starter from the glow plug. Advance the throttle barrel to full throttle. Adjust the high speed needle valve so that the engine continues to run rich. Let the engine run for approximately 5 minutes at full throttle then stop the engine.
# Let the engine cool for approximately 10 minutes then restart it. Advance the throttle to full and set the high speed needle valve to a slightly leaner setting. Let the engine run for about 5 minutes at this setting then stop the engine and let it cool for approximately 10 minutes.
# Repeat the procedure in step # 7, while setting the high speed needle valve slightly leaner each time. In all, you should run the engine about a total of 40 minutes of actual running time. The engine is fully broken-in when it will hold a peak R.P.M. setting at full throttle for about 5 minutes with no tendency to fluctuate or overheat. After the break-in period is completed the engine is ready for flight.

EINLAUFEN

Hinweis: Da der Kolben dieses Motors nicht mit einem Ring versehen ist, sondern so geschliffen ist, dass er fest in der Zylinderbuchse läuft, spüren Sie beim Drehen des Motors einen großen Widerstand. Das ist normal. Sobald der Motor auf Betriebstemperatur aufgewärmt und richtig eingelaufen ist, wird dieser Widerstand nachlassen und das richtige Spiel für den Betrieb wird erreicht. Versuchen Sie unter keinen Umständen, den Motor zu

zerlegen und die Kolbenreibflächen zu manipulieren. Dies würde nur zum Verlust der Garantie führen. Befolgen Sie einfach das unten beschriebene Einlaufverfahren. Das Einlaufen ermöglicht es den beweglichen Teilen des Motors, sich unter der Einwirkung hoher Temperaturen und Drücke zu „beruhigen“, wodurch die Gefahr eines vorzeitigen Verschleißes vermieden wird. Der Einfahrkraftstoff darf nicht mehr als 15% Nitromethan und nicht weniger als 20% Rizinusöl enthalten. Während der Einlaufphase dürfen keine Kraftstoffe

mit synthetischem Öl verwendet werden. Zum Einlaufen empfiehlt es sich, den Motor in das Modell zu montieren, in dem er künftig betrieben werden soll. Dabei werden nicht nur der Motor, sondern auch die gesamte Kraftstoffanlage und die RC- Gassteuerung getestet und eingestellt. Ist eine Motorabdeckung am Modell vorhanden, sollte diese beim Einlaufen entfernt werden.
