如果喷溅燃油点火，会造成人身伤亡。 泄漏或溅溢到热表面或电气部件上的燃油会引起失火。 为防止可能的伤害，当更换燃油滤清器或油水分离器滤芯时，要将蓄电池断路开关转到断开位置。 应立即将溅溢的燃油清除干净。 |

- 用带式扳手拆卸燃油滤清器滤芯。 废弃用过的滤清器。
- 清洁滤清器壳体基座。 确保将所有旧的密封件已去除。
- 在新滤清器滤芯的密封表面上涂上清洁的柴油。
- 用手安装新滤清器。 拧紧滤清器滤芯，直到密封表面接触到滤清器底座。 滤清器滤芯再拧紧3/4 圈。
注: 每个滤清器上有旋转标记，间隔90度(1/4圈)。 在紧固滤清器时，用这些标记作参考。
- 向燃油系统充油。
参考关于被维修机器的燃油系统充注的详细资料，参阅操作和保养手册, "燃油系统 - 充油"。
- 起动发动机，并检查滤清器有无泄漏。 进行所有必要的修理。
