开始:

  1. 安装车轮楔子。 请参阅拆解和组装, "车轮楔子(前和后)- 拆卸和安装"。


注意

在检查、保养、测试、调整及维修产品时,请小心确保盛接油液。 在打开任何舱室或拆卸任何含有油液的部件前,请准备好盛接液体用的适当容器。


注: 以下程序对于机器两侧完全相同。 必要时,对机器的另一侧重复此程序。

注: 将盖和塞安装在全部孔口上,以免污垢或碎屑进入系统。 清洁度是一项重要的因素。 拆卸步骤开始之前,应彻底清洁部件外部。 这将防止脏污进入内部部件。

  1. 排放液压油箱(举倾机构和制动器)。 请参阅操作和保养手册, "举倾机构和制动器油箱油 - 更换"。 液压油箱(举倾机构和制动器)的容量为 133 L (35 US gal)
