There are 2 connecting holes in the lower link and
lifting rod: front hole "C" and central hole ”B". When
operate normally, usually connect the central hole “B";
while it is necessary to transfer at a long distance with
farm implements, shall connect the front hole “C”.
The connecting hole of the lower link and positon-
limit rod is the rear hole "A".

右提升杆的调整均可通过转动中间提升杆导管焊合来进行。顺时针转动，提升杆伸长：反之则缩短。调
整提升杆主要是对农具的横向水平位置进行调整。
Usually the lifter length should be adjusted to the medium length. You could adju.st left/right lifting rod by
turning the pipe solder of the central lifting rod. The lifting rod will lengthen if turn clockwise; otherwise,
shorten. Adjust the lifting rod is mainly to adjust the transverse and horizontal position of the farm implements.

上拉杆连接
Connection of upper link
上拉杆与支座的连接有
3
个孔供选用，可根据农具的立柱高度选用合适的位置。一般情况下，当立柱高
度小于或等于
510mm
时，选用下孔，当立柱高度在
5lOmm-6lOmm
之间时选用中间孔，当立柱高度大
于
161mm
时选用上孔。也可根据实际情况适当调整。调整上拉杆长度主要用来调节农具的纵向水平位
置，调整前后犁耕深的一致性。
3 holes are optional between the connection of the upper link and the base. Choose the proper position
according the height of the upright post of the farm implements. In general conditions, choose the lower hole if
重要事项：
IMPORTANT:
不用快换接头时，座孔一定要用备用防尘盖盖好。
When the quick joint is not used, its socket hole shall be covered with dust coverto avoid dust;
提升器和液压输出阀不能同时使用。
Lifter and hydraulic output valve can not be used simultaneously.
液压输出阀操纵完成后，操纵手柄必须回到中立位置，否则将引起液压系统过热。
After hydraulically output device is operated over, its operating handle should be set to neutral position,
otherwise, which may cause hydraulic system overheat
