、该发动机并非玩具，请特别注意安全，由此引起的所有安全问题我们将不予负责：
Gasoline engine is not a toy. Serious injury may result from improper use. We are not
responsible for any injury, damage or other loss resulting from its use.
2
、使用前请仔细检查螺旋桨、发动机架等相关部位，保证螺丝、镙母不松动，安装时最好使用
螺纹胶（如：
LOCTITTE 242
）固定螺丝、螺母。
Before every use, check the engine assembly, propeller and airframe carefully for loose screws
and nuts. Loctite is strongly recommended on all the screws.
3
、请注意：如果要在试车台上磨合或测试发动机，必须有很好的减震装置，否则可能导致发动
机部分零件的损坏，最好把发动机安装在飞机上进行磨合。
During the break-in process, engine must running with shock absorber installed. Or the
engine will be seriously damaged by vibration. The best way for break-in process is mount
the engine on a plane.
4
、发动机在运行时，任何人不许在螺旋桨旋转平面前的位置。
Always stand clear of and behind the propeller; never allow anyone including yourself, to be in front
of or to the sides of the propeller when starting or running the engine. Anyone near the engine
should wear protective eyewear. Do not wear loose clothing near the engine or propeller.

三、发动机的调整
(ENGINE ADJUSTMENT)
1
、每台发动机出厂时都经过了初步调整，用户可以直接使用。但各地区的海拔高度将会影响
化油器的正常工作，化油器油针可能需要进行微调才能达到最佳的工作位置。
Every engine has been adjusted to average mixture settings which will most likely allow the engine
to start and run in most locations. However, as altitudes and barometric pressures vary by location,
it is very likely that the carburetor mixture settings will need to be adjusted to obtain optimum
performance.
