Tunnel loader is an essential mining equipment for mining enterprises and an alternative product of labor and other machinery. The premise of mine construction is safety, which is the same requirement for the use of tunnel loader. Therefore, we should check the following relevant technologies before starting the machine:

1、应该检查电源系统：电缆、接头应该确保完好，无破损的现象；连接线路应完好，无烧损、松脱现象。

1. First, check the power supply system: cables and connectors should be intact without damage; The connecting line shall be intact without burning and loosening.

2、检查装载机的液压系统：液压系统的元件及其联接管路之间连接应紧固，无明显渗漏现象；液压油位应符合规定（油量约占油箱总容积的4/5之间）。

2. Check the hydraulic system of the loader: the components of the hydraulic system and their connecting pipelines shall be firmly connected without obvious leakage; The hydraulic oil level shall meet the requirements (the oil volume accounts for about to 4 / 5 of the total volume of the oil tank).

3、检查矿用装载机的操纵系统：各操纵手柄应处于中立位置，操纵应灵活，无卡滞现象。

3. Check the operating system of the mine loader: each operating handle shall be in the neutral position, and the operation shall be flexible without jamming.

4、检查加力泵内刹车油的油位；

4. Check the brake oil level in the booster pump;

5、松开柴油箱底部放油螺栓排除油箱内部残余的水分；

5. Loosen the oil drain bolt at the bottom of the diesel tank to drain the residual water inside the tank;

6、检查液压油箱的油位；检查发动机机油油量、水箱水量、变速器和柴油箱以及工作油箱油量；

6. Check the oil level of the hydraulic oil tank; Check the oil quantity of engine oil, water quantity of water tank, oil quantity of transmission, diesel tank and working oil tank;

7、检查驱动桥制动摩擦片的使用情况及制动钳有无漏油现象；

7. Check the service condition of the drive axle brake friction plate and the brake caliper for oil leakage;

8、检查隧道装载机刹车系统是否灵活，将脚踏阀放在中位，即刹车。如果长时间停止需要将机头产板压住地面。

8. Check whether the braking system of the tunnel loader is flexible, and put the foot valve in the middle, that is, braking. If it stops for a long time, it is necessary to press the production plate of the machine head against the ground.
