1) 关闭风门，转动螺旋桨,直至油料进入化油器
2) 此时打开点火电源。
3) 用力转动螺旋桨， （最好使用启动棒）直到发动机发出爆炸声，发动机会运转 1-2 秒而自动
熄火。 （首次启动或长时间不用可能需要转动多次螺旋桨） 。
4) 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。
5) 热车启动：打开风门，油门开至怠速或比怠速稍大一点，直接启动发动机。
Starting the Engine
a) With the ignition off, throttle set to full speed, close the choke and rotate the propeller
(anti clockwise from the front) until the fuel appears at the carburetor fuel nipple.
b) Turn on the ignition.
c) Flip the propeller firmly in an anti clockwise direction (looking from the front). We
recommend the use of a start-up stick and/or a leather glove. The engine will make
popping sound and run for 1-2 seconds. For the first time use or if the engine hasn't been
used for a while, you may need to flip the propeller up to 10 times.
d) Open the choke, set throttle valve at the idle position or at a position slightly open from
idle, then start up the engine again as above ( 3)
e) If the engine is still warm from prior operation you can start the engine as per (4).
1，磨合期内，建议使用 20-25：1 的油料
2，当发动机运行在怠速状态（绝对不要超过 4000 转） ，感觉转速不稳定时，小小的加一下油
门。运行 30 分钟后熄火检查，并使引擎自然冷却。重复以上过程，直至引擎累计磨合 2
小时。
3，现在可以飞行了，但请注意以下几点
·不要让引擎转速超过 7000 转
·让引擎处于良好的冷却环境中
·熟悉一下你的引擎和飞机飞行航线吧！
·引擎累计运行 20 小时后才算磨合完成
Engine break in
1，During the engine break in period, it is recommended to use a fuel mixture of 25-30:1.
2，After the engine starts, run it at a fast smooth idle speed (no more than 4000 rpm ) After
30 minutes running, stop the engine and then check the mounting and the tightness of
the propeller. Let the engine cool down naturally. Repeat the above process until the
engine has an accumulated break in of 2 hours.
3，Now you are ready to fly, but please pay attention to the following points:
a) Do not let the engine speed exceed 7,000 rpm
b) Check that the engine is getting adequate cooling
c) After an accumulated running time of 20 hours, your engine can be considered to
be completely run in.
d) Please familiarize yourself with your engine operation and the safe operation of
your aircraft.
