如图（1）（2）所示， 泵顶上那两个手柄就是挂档手柄 ，有4个档位，

As shown in figure (1) and (2), the two handles on the top of the pump are gear shift handles, with 4 gear positions, and the flow rate corresponding to the gear positions is shown in figure (3). The gear can be changed by the handle to achieve the purpose of changing the flow. If you want the flow to reach 850l/min, you only need to adjust the gear to Ⅳ

As shown in Figure (1) (2), the two handles on the top of the pump are the mount handle, there are 4 gears, the corresponding flow rate of the gear is shown in Figure (3). Through the handle to change gear, to achieve the purpose of changing the flow. If you want to reach 850l/min, you only need to adjust the handle gear to IV.

As shown in figure (1) (2), the two handles on the top of the pump are the shift handle, which has four gears, and the corresponding flow rate is shown in figure (3). If you want the flow rate to reach 850l / min, just adjust the handle gear to IV<br>
