  1. 将作业机具置于完全后倾位置。 将提升臂降至最低位置。 关闭发动机。

  1. 应当根据下表设定调整杆。

    表 1
    型号     尺寸 (A)    
    928F、928G    
    284 mm (11.2 in)    
    938F、 938G    
    284 mm (11.2 in)    
    950F- 980F    
    245 mm (9.6 in)    
    950G、 962G、 980G    
    215 mm (8.5 in)    
    966G、 972G    
    170 mm (6.7 in)    
    988 到 994    
    149 mm (5.9 in)    

    注: 只有表 1 中所列机器上的提升连杆位置传感器才可调。 如果所维修的机器不在该表中,则提升连杆位置传感器不可调。

  1. 将连杆组件连接到位置传感器的钩环 (1) 和杠杆 (2) 上。

  1. 确保杠杆 (2) 可以在位置传感器的轴 (3) 上自由转动。

  1. 将有效载荷控制系统(PCS)置于称重模式。 按 "SERV" 键。

  1. 单击 "NEXT FUNCTN(下一功能)"键。 显示屏将显示提升臂的当前位置。 测量单位与提升臂的角度有关。

    注: 不要将位置传感器伸过最大限位。 否则可损坏位置传感器。

  1. 顺时针转动轴 (3) ,直到感到阻力。 记录显示屏上显示的最大位置。

  1. 通过转动轴 (3) 获得 6500 和 25000 间的读数。 上紧将杠杆 (2) 固定到轴 (3) 上的螺栓。

  1. 起动发动机。 缓慢升起提升臂的同时观察显示屏上的读数。 如果读数达到步骤 7 内的数值减去 1500,则使提升臂返回完全降下位置。 通过缩短调整杆的长度获得较低读数。

  1. 重新升起提升臂的同时观察显示屏上的读数。 读数应当在 44500 和 61600 之间。 如果读数超过 61600,则重复步骤 8 到步骤 10。 重复这些步骤时,采用较低的读数。
