A model airplane engine is capable of causing serious injury to yourself and others if  you fail to observe proper safety precautions while using it.
	Keep spectators (especially small children) at least 20 feet away from the engine while it is running.
	Mount the engine securely in the airplane or on a suitable engine test stand to run the engine.
	Follow the mounting instructions in your kits instruction manual or on the plans for individual mounting recommendations.
	Do not clamp the engine in a vise to test-run it.
	Use the recommended size propeller and follow the proper procedure for mounting the propeller.
	Use the correct size wrench to tighten the propeller nut and the safety nut. (Do not use pliers!)
	Inspect the spinner, propeller and safety nuts on a regular basis (look for any signs of nicks, cracks or loosening)
	To stop the engine adjust the throttle linkage to completely close the throttle barrel and therefore cut off the fuel/air supply. You can also pinch the fuel line to stop the engine, but only if it is accessible.
	Do not throw anything into the spinning propeller or attempt to use your hands to stop the engine.
	Stand behind the engine to make any adjustments to the needle valves when the engine is running.
	Do not reach over or around the propeller.
	Do not wear loose clothing or allow anything to be drawn into the spinning propeller while the engine is running. (Ignoring the two rules above are probably the most common cause of serious injury in this hobby)
	If you absolutely must carry your model while the engine is running approach the plane from the muffler side so you support the wing on the side away from slippery fuel from the exhaust and use the other hand to support the fuselage.
	Keep unsecured airplanes pointed away from you and others at all times.
	Do not use tight-fitting cowls over the engine. They can restrict air from flowing over the engine, which could result in engine damage from overheating.
