拖拉机出厂时，提升器已调整好，
用户一般无 需调整。但在使用过程中，
由于杆件传动副的磨损和紧固件的松
动，提升器原始调整状态被破坏而引起
工作不正常，或提升器修理后装配时，
均需进行提升器的调整。提升器的调整
方法和顺序如下
(

：
The hydraulic hitch system has been
adjusted in factory. Generally, users do
not need to adjust it. However, in use
process, the hydraulic hitch system needs
to be adjusted if there are abnormalities
due to the original state damage of the

把分配器操纵手柄
6
扳至最低下降位置，保持固定不动。
Put control handle 6 of the distributor tothe lowest position and keep it immobilize.
启动发动机将操纵手柄
6
慢慢向提升位置移动，这时外提升臂
2
也不断向提升方向移动。
Start the engine and slowly move the control handle 6 to the lifting position, at this time, the outer arm 2
also moves towards the lifting position.
若操纵手柄
6
移动到最高提升位置，而外提升臂
2
没达到最高位置，就应调整调节螺套
If the control handle 6 is moved to the highest lifting position, while the outer arm 2 has not reach the
highest position , adjusting screw set 4 should be adjusted to increase the distance between feedback arm
of the distributor and the central arm so that the outer arm moves upward to a position whose angle with
the horizontal line is 60º, lock locking nut 5, At this time, the engraved lines of the outer arm is in
alignment with that of the of the hydraulic hitch system. Repeat the process for 3 times and the hydraulic
hitch system will work properly, that is, adjust is finished.
若操纵手柄

尚未移到最高位置，而外提升臂

已达到最高位置，就应调整调节螺套

缩小反馈臂
到中间臂的距离。当操纵手柄

次，提升器工作正常，即调整完毕。
If the control handle 6 is not moved to the highest lifting position, but the outer arm 2 has not reach the
highest position
，
adjusting screw set 4 should be adjusted to decrease the distance between feedback arm
of the distributor and the central arm. When both the control handle 6 and the outer arm 2 have reached
the highest lifting position, tighten locking nut 5. Repeat the process for 3 times and the hydraulic hitch
system will work properly, that is, adjust is finished.
重要事项：
Important notes:
使用需要带动力输出的机具时，为了避免机具提升过高，造成连接动力输出轴与机具的传动轴因夹
角过大而损坏，要求机具提离地面且能保证地头转弯不受影响的提升高度为准。
