Translations:KAVAN AP06A - Instruction Manual/23/en

Remember that the engine is not a toy, but a beautiful product of fine mechanics, which, if handled incorrectly, can cause serious injury to you or other people, or significant property damage.

Do not allow especially small children and other spectators, who could be injured as a result of operating your engine, to come too close. The safe distance is at least 5–6 m (20 feet) away from the engine while it is running. No one should stand in line with the rotating propeller!
Always mount the engine to a solid and reliable mount using steel bolts with lock nuts. Never clamp the engine directly in a vice. To mount the engine to the model, use a high-quality, properly dimensioned engine mount recommended by the designer, model manufacturer, or specialist dealer. Make sure that all bolts are properly tightened.
Use a propeller of the correct diameter and pitch. Follow the instructions in the Instruction Manual, on the model plan, or seek advice from a specialist dealer. Keep in mind that plastic propellers, especially those with larger diameters, may require special handling - always follow the propeller manufacturer's instructions.
Mount the propeller in the correct orientation (when viewed from the "cabin" of the model, the propeller in the pulling configuration is always clockwise; when viewed from the front, it rotates counterclockwise). Always tighten the propeller nut carefully and firmly with the appropriate washer using the correct wrench and check the tightness regularly during operation. Use only undamaged and well-balanced propellers.
Ensure that your face and other parts of your body are not within reach of the propeller when starting the engine. Do not lean over the propeller when adjusting the carburettor while the engine is running.
Protect your fingers from being “bitten” by the propeller as much as possible. For manual starting, use a sturdy leather glove or a special finger guard that can be purchased at model shops. Using an electric starter is a very safe way to start the engine.
Adjust the carburettor only from behind the engine and the rotating propeller.
Stop the engine only by completely closing the carburettor or by cutting off the fuel supply by pinching the fuel line. Never try to stop the rotating propeller with your fingers, hand or any other part of your body. Never throw anything into a spinning propeller in an attempt to stop it.
Immediately discard any propeller with cracks, breaks, scratches or any signs of material fatigue or damage. Never attempt to repair or modify a propeller. Normal vibrations associated with engine operation can cause the propeller nut to loosen - check the tightness regularly and frequently.
If you need to carry your model while the engine is running, be conscious of the spinning propeller. Keep the aeroplane pointed away from you and others.
Do not use tight-fitting cowls over the engine. They can restrict air from flowing over the engine, resulting in engine damage from overheating.
