Runaway means that engine speed is too high and out-of-control. It exceeds the maximum operating
speed greatly. Runaway is extremely harmful to diesel engine. When it occurs, immediately stop the
engine as follows:
1）切断油路：将油门拉到停车位置，关闭油路开关。当油门失去对油泵柱塞控制时，拧开高
压油管联接螺母。
Shutoff fuel line: Pull throttle to STOP position, and turn off fuel switch. When throttle loses control to
fuel pump plunger, loosen fuel injection pipe coupling nut.
2）切断气路：柴油机有防爆装置等机构时，利用它将进气道迅速关闭，用棉衣抱住空气滤清
器。总之只要切断进气通道就能迅速停车。飞车时绝对禁止减小或卸掉负荷，停车后应分析和查找
原因，及时排除。
Shutoff air passage: You can use explosion-proof equipment if available on your diesel engine to close
air inlet channel immediately, and cover air filter with cotton quilted coat. In any case, engine can be
stopped immediately if air inlet passage is cut off. DO NOT attempt to reduce load or unload the engine.
You MUST analyze and identify the causes, and duly remove the failure.
