2、更换发动机机油，新机油通常呈中性，不会腐蚀发动机的金属机件。

2. Change the engine oil. The new oil is usually neutral and will not corrode the metal parts of the engine.

3、燃油箱加满柴油，避免燃油箱生锈，如条件允许还应加入防腐剂。

3. Fill the fuel tank with diesel to avoid rusting of the fuel tank. If conditions permit, add preservatives.

4、在停机期间应每月启动一次发动机，使机械作短距离行驶，使各零件润滑处建立新的油膜，防止生锈。此处需要注意：在启动前应注满冷却水，结束时应放尽冷却水。

4. During shutdown, the engine shall be started once a month to drive the machinery for a short distance, so as to establish a new oil film at the lubrication part of each part to prevent rust. It should be noted here that the cooling water should be filled before startup and drained at the end.

蓄电池的保养

Battery maintenance

1、应拆下蓄电池，将蓄电池放置在干燥和防冻处，要保持其表面的清洁干燥，严禁在蓄电池上放置导电物体。拆蓄电池时，要切断负极线，然后再切断正极线，安装时要先连接正极线，再连接负极线，因工程机械电气系统都是负极搭铁，这是为了防止拆装蓄电池时造成短路。

1. The battery shall be removed and placed in a dry and antifreeze place. Its surface shall be kept clean and dry. It is strictly prohibited to place conductive objects on the battery. When removing the battery, first cut off the negative wire, and then cut off the positive wire. During installation, connect the positive wire first and then the negative wire. Because the electrical systems of construction machinery are grounded at the negative pole, this is to prevent short circuit during battery disassembly and assembly.

2、铅酸蓄电池应每月充电一次。

2. Lead acid batteries shall be charged once a month.

防锈处理

Antirust treatment

1、存放前，应视外表面防锈漆漆皮脱落面积的大小，来确定用补漆还是整机重新喷漆的方法进行修补。

1. Before storage, it shall be determined whether to repair with touch up paint or repaint with the whole machine according to the size of the peeling area of the antirust paint on the outer surface.

2、工程机械的工作装置，对其金属裸露处的防锈方法是涂抹黄油。

2. For the working device of construction machinery, the antirust method for the exposed metal is to apply butter.

空调的保养

Maintenance of air conditioner

空调除了夏季，多数时间处于不使用状态，在空调闲置时更要进行检查，更好应该每月保证操作空调器35分钟时间，防止长时间不用出现故障。

In addition to summer, the air conditioner is not in use most of the time. It should be checked when the air conditioner is idle. It is best to ensure that the air conditioner is operated for 3 to 5 minutes every month to prevent failure for a long time.
