一、 安全（SAFETY INSTRUCTIONS） 1、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，安装时一定要 使用螺纹胶（如：LOCTITTE 242、243等）固定螺丝、螺母。安装螺旋桨不使用螺纹胶会导致固 定螺丝被螺旋桨全部切断。 Before every use, check the engine assembly, propeller and airframe carefully for loose screws and nuts. Loctite(242,243) is strongly recommended on all the screws.Otherwise propller could cut off the bolts during the flight. 2、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.
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.
（首次启动或长时间不用可能需要转动多次螺旋桨） 。 Step 2:, briskly flip the prop through compression until the engine fires and then dies. It may take a few more flips if this is first time to start the engine after being stored for a long period. （3）打开风门，油门开至怠速或比怠速稍大一点,启动发动机，进入正常工作状态。 Step 3: Open the choke and briskly flip the prop through compression, advance the throttle to very slightly above the idle position, the engine should start in just a few flips.
