The gas mixed in the hydraulic fluid of small loader will affect the braking performance. Exhaust after replacing parts and cleaning the system. The exhaust method is as follows:

（1）清理液压管路、贮油室等处的积垢。

(1) Clean up the scale at the hydraulic pipeline, oil storage chamber, etc.

（2）加满制动液。

(2) Top up the brake fluid.

（3）启动发动机，待空气压力表读数为0.68~0.7MPa后停车。

(3) Start the engine and stop after the air pressure gauge reads 0.68 ~ 0.7MPa.

（4）放气嘴上套入放气用的透明管，管的另一端放入盛油盘中。

(4) A transparent pipe for air bleeding is sleeved on the air bleeding nozzle, and the other end of the pipe is put into the oil pan.

（5）连续踏下紧急制动踏板，松开制动踏板。放气时，还要向贮油室及时补充制动液，以免空气再度进入系统。

(5) Continuously press the emergency brake pedal and release the brake pedal. When deflating, add brake fluid to the oil storage chamber in time to prevent air from entering the system again.

3.工作压力调整

3. Working pressure adjustment

出厂时，压力已作调整。使用后，若气压小于0.68·0.7MPa，应作调整。将压力控制器的调整螺栓顺时针旋转，压缩弹簧，使压力达到0.68~0.7MPa，将螺母锁紧。若气压过高，则作相反的调整。

When leaving the factory, the pressure has been adjusted. After use, if the air pressure is less than 0.68 · 0.7MPa, it shall be adjusted. Turn the adjusting bolt of the pressure controller clockwise, compress the spring to make the pressure reach 0.68 ~ 0.7MPa, and lock the nut. If the air pressure is too high, make the opposite adjustment.

4.制动性能检查

4. Brake performance inspection

小型装载机制动性能的好坏关系着运行的效率，经过拆修的 制动系统应检查制动性能是否处于良好状态。在平直、干燥的水泥路面上以24km/h速度行驶，用脚制动时其制动距离不大于9m。以30km/h速度行驶，点试制动，应迅速出现制动现象，且不偏跑。

The braking performance of small loader is related to the operation efficiency. The braking system after disassembly and repair should check whether the braking performance is in good condition. When driving on a flat and dry cement road at the speed of 24km / h, the braking distance shall not be greater than 9m when braking with feet. When driving at the speed of 30km / h, the braking phenomenon shall occur quickly without deviation.

5.保养

5. Maintenance

（1）清洁。制动器的清洁能更好地发挥其制动效能，早期发现故障。

(1) Cleaning. The cleaning of the brake can give better play to its braking efficiency and find faults early.

（2）检查。经常检查脚制动系统有无泄漏，各种接头、连接部分有无松动，总液压泵液面是否正常，管路是否通顺，无泄漏。检查橡胶零件是否老化变质。

(2) Check. Frequently check whether the foot brake system has leakage, whether various joints and connecting parts are loose, whether the liquid level of the master hydraulic pump is normal, whether the pipeline is smooth and free of leakage. Check whether the rubber parts are aged and deteriorated.
