需要正确调整位置开关,以便使行车制动器和摆动轴锁定正常工作。

机器准备

  1. 使所有人员远离机器和机器周围。

  1. 起动发动机。

  1. 降下左侧操纵台。

  1. 将机器停放在水平地面上。 检查视野并调整反光镜,使机器附近的视野达到最佳。

  1. 降下稳定器和铲刀尖。

  1. 完全伸出铲斗油缸,然后将铲斗置于地面上。

  1. 停止发动机。

  1. 释放液压系统压力。 请参阅测试和调整, "液压系统压力 - 释放"。

  1. 举升左操纵台。

注: 执行下述"调整"步骤前,执行步骤 1 至 9。

    (X) 间歇尺寸

  1. 完全接合行车制动器踏板 (1) 并将行车制动器踏板置于锁定位置。 确保位置开关与磁铁之间没有接触。

    注: 踩下行车制动器踏板时应小心。 由于没有压力,行车制动器踏板很容易踩下。 如果磁铁与位置开关接触,位置开关可能损坏。

  1. 检查位置开关 (3) 与磁铁 (2) 之间的间隙尺寸 (X) 。 间隙尺寸 (X) 必须为 1 至 2 mm (0.040 至 0.079 inch)。

  1. 如果间隙尺寸不符合技术规格,转至步骤 7。

  1. 弯曲支架 (4) 以获得所需的间隙尺寸 (X) 。

  1. 清除操作员监视器上的所有代码。
