Send it to repair if necessary.

停机：
Engine shutoff

停车前怠速运行
3
～
5
分钟后才熄火，避免急速停车，特别是高转速高负荷运转时更应
如此。
 The engine is shut off after 3~5 min operation at idle speed when the vehicle stops.
Sudden stop shall be avoided, especially when the engine operates at high speed
with heavy load.

每次停车后，必须及时排除在运行期间所发现的故障，并经常进行必要的检查，保证柴
油机正常的技术状态。
 The malfunctions in operation shall be eliminated timely after stop; necessary
inspection is required regularly to ensure the normal technical status of the diesel
engine.

柴油机的维护保养：
Maintenance of the diesel engine

磨合：
Run-in period:
 新柴油机（或刚大修好的柴油机）必须进行先期磨合，以此改善各摩擦副的配合及提高
工作能力，这对保证柴油机工作可靠性及使用寿命至关重要。
 Early run-in shall be carried out for new diesel engine (or diesel engine after overhaul)
to improve the matching of friction parts and the working ability. It is quite important to
guarantee the reliability and long lifetime of the diesel engine.
 磨合时间为 40 ～ 50 小时，磨合期的功率和转速应由低到高，但最大不应超过标定功率
的
80%
。

The run-in period lasts 40
～
50 hours. The power and speed when run-in shall be
increased gradually, but the max power shall not exceed 80% of the rated power.

磨合期结束后更换机油、机油滤清器。
 Replace the oil and oil filter after the run-in period

严禁长时间怠速和低速磨合，否则容易造成早期磨损、烧油嘴等故障。（有些用户将正
常的磨合等同于怠速磨合，机器买回来后长时间怠速磨合，其实这种做法是错误的，磨
合期是可以进行工作的，只要不超负荷就可以了）
 It is forbidden to operate at idle speed and low speed for a long time in run-in period,
otherwise, early wearing and burnt fuel nozzle may be caused. (some users take
normal run-in the same as idle speed run-in, and operate the engine at idle speed for
a long time. The above operation is incorrect. The engine could work in run-in period
with proper load.)
