起动发动机养成在起动发动机之前必先直观检查发动机和发动机房的习惯。

这有助于你及时发现已经发生和将要发生地各种异常情况。

发动机起动后，还要检查仪表的示值是否正常。

起动之前·检查润滑油油位是否在MIN（最低）和MAX（最高）标记之间，见“润滑系统的维护保养”。

·打开燃油开关·确认冷却液、燃油或润滑油无泄漏·检查空气滤清器的阻塞指示器，见“发动机一般保养”。

·检查冷却液液位和散热器的外部有无堵塞，见“冷却系统的维护保养”。

警告提示！发动机高温时不要打开冷却液加液口盖，蒸汽或高温冷却液会喷射出来。

·接通主电源开关重要事项！发动机运行时切勿用主电源开关断开电源，以免损坏充电发动机。

·将发动机的转速设置在怠速，脱开分离式离合器/齿轮箱（如果装有）。

EDC4的起动方法起动前，必须将发动机的转速控制杆置于怠速位置。

EDC4系统保证发动机始终接受到精确地燃油量—即使在冷起动时。

起动发动机。

如果发动机装有预热器，预热时间可根据发动机的温度来调整。

严寒环境下起动发动机为有助于发动机的启动和一定条件下使发动机能够起动成功，必须作好以下准备工作。

使用经认可适用于当地气温的冬季燃油（知名品牌），这可以减少在燃油系统内产生蜡质沉淀的危险。

在环境温度极低的情况下，建议使用燃油加热器。

为了确保有足够的润滑，建议使用粘度适合于当地温度的合成润滑油，见“润滑系统的维护保养”：合成润滑油比矿基润滑油能适应更大的温度范围。

用外加配置的发动机电加热器预热冷却液。

在极端情况下，可能需要使用燃烧柴油的发动机加热器。

请向你的V olvo Penta 经销商咨询。

重要事项！确保冷却系统内已加注乙二醇混合液，见“冷却系统的维护保养”。

蓄电池必须处于良好状态。

低温会降低蓄电池的容量，可按需要增加蓄电池的总容量。

切勿使用起动喷射液警告提示！切勿使用起动喷射液或类似物品来帮助发动机起动。
