在检验、保养、测试、调整及维修发动机时，请小心确保盛接流出的液体。 在打开或拆解任何储有液体的部件之前，要准备好合适的容器收集液体。 有关适合收集和盛接卡特彼勒产品上的液体的工具和供应品，请参阅专门出版物, NENG2500, "卡特彼勒代理商工具目录"。 按照本地法规和条例处置所有液体。 |

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。 |
- 将工具 (A) 安装到液压油箱上。 将一条供气软管连接到工具 (A) 上。 施加 276 到 414 kPa（40 到 60 psi）的气压。 此步骤将使液压系统抽吸出真空。
- 将螺塞 (1) 和 O 形密封圈从弯头上拆下。
