高温机油或高温部件可能会导致人身伤害。 在工作温度下，机油温度高，压力高。 热油能造成烫伤。 只能在发动机停机且加注口盖充分冷却到可以徒手触及时再卸下加注口盖。 不让高温油或部件与皮肤接触。 |

滚热的油或液压油的压力会对人员造成伤害。 发动机停机之后，液压油的压力仍会保留在液压系统里。 对液压系统进行维修之前，如果不事先释放压力，可能会造成严重伤害。 卸下机具和其油路之前，必须先把机具放到地面上，让油先冷却，才可进行工作。 只能在发动机停机，并且加注口盖冷却到可以用徒手触摸时才能卸下加注口盖。 |
- 安装车轮楔子。 请参阅操作和保养手册, "车轮楔子的使用"。
- 将液压油箱中的油排入合适的容器以便保存或废弃这些油。 请参阅操作和保养手册, "液压油箱 - 更换 - 举倾和制动系统"。
