1、严格按照操作规程和驾驶要领进行操作，尽量避免换挡时"打齿"，以减少齿轮副的磨损。

1. Operate in strict accordance with the operating procedures and driving essentials, and try to avoid "cogging" when shifting, so as to reduce the wear of gear pair.

2、严格执行保养制度，加强换挡装置的维护保养。当换挡装置杆系连接不当时应及时调整，确保换挡装置性能良好。

2. Strictly implement the maintenance system and strengthen the maintenance of the shift device. When the linkage of the gear shifting device is not connected, it should be adjusted in time to ensure the good performance of the gear shifting device.

3、注重对自锁机构的维修与保养，对定位作用降低或失去定位效能的定位钢球、弹簧及拨叉轴，应及时修复或更换，使自锁机构的自锁性能处于良好的状态。

3. Pay attention to the repair and maintenance of the self-locking mechanism, and timely repair or replace the positioning steel ball, spring and fork shaft whose positioning function is reduced or lost, so that the self-locking performance of the self-locking mechanism is in a good state.

4、组装变速器时，应严格按操作规程进行操作，确保变速器各机件调整正确、紧定适当。较大的下坡路面时，驾驶员应严格按照下坡的动作要领进行操作，切不可违规。

4. When assembling the transmission, the operation shall be carried out in strict accordance with the operation procedures to ensure that all parts of the transmission are adjusted correctly and tightened properly. In case of large downhill road, the driver shall operate in strict accordance with the action essentials of downhill, and must not violate the rules.

在长臂挖掘机的行驶过程中，若出现变速器"跳挡"时，应及时使机器停机，然后查找原因，排除故障。具体方法是：

In the process of driving the long arm excavator, if the transmission "jumps" occurs, the machine should be shut down in time, and then find out the cause and eliminate the fault. The specific methods are as follows:

1、在平路上行驶时出现"跳挡"，可按正常的停机要领停机，认真查找原因，排除故障。

1. In case of "jumping gear" when driving on a level road, stop the vehicle according to the normal stop essentials, carefully find out the cause and remove the fault.

2、在下坡道上行驶时出现"跳挡"，应按加挡的动作要领将挡位置于高-速的位置或采取"抢挡"措施，待机器行驶到坡底后再停机检查，排除故障;若"加挡"、"抢挡"不成功或又一次出现"跳挡"时，驾驶员可将发动机转速控制在中速，采用"点刹"的方法使机器滑坡底，然后排除故障。

2. In case of "jumping gear" when driving on the downhill, the gear should be set at the high-speed position according to the action essentials of increasing gear, or the "rush gear" measures should be taken. After the machine reaches the bottom of the slope, it can be stopped for inspection and troubleshooting; If the "upshift" and "scramble" are unsuccessful or the "jump" occurs again, the driver can control the engine speed at medium speed, use the "point brake" method to make the machine slide to the bottom of the slope, and then remove the fault.

3、上坡行驶时出现"跳挡"，可将挡位置于低-速位置或Ⅰ挡位置，待机器行驶到坡顶时再停机，排除故障;若减挡不成功或又一次出现"跳挡"时，应按坡道停机的动作要领及要求停机，然后排除故障。

3. In case of "jumping gear" when driving uphill, you can put the gear in low speed position or I gear position, and stop the machine when the machine reaches the top of the slope to remove the fault; If the downshift is not successful or "jump" occurs again, stop according to the action essentials and requirements of ramp stop, and then remove the fault.
