拆卸步骤

开始:

  1. 安装车斗固定销。 请参阅拆解和组装, "销(车斗固定)- 拆卸和安装"。

------ WARNING! ------

失火会造成人身伤害或死亡。

渗漏或溅溢到热表面或电气部件上的燃油会引起失火。

要擦净所有泄漏或喷溅的燃油。 对燃油系统进行工作时不要吸烟。

更换燃油滤清器时,要将断路开关转到“断开”位置或断开蓄电池。



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: 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机构。
