2.延长杆

工作空间有限时,或所备的套筒难于碰到所要旋 紧的螺母时,使用延长杆是极其方便的。

注意

使用延长杆时,与普通转矩相比,旋紧转矩会稍 微变小。因此,要想获得同样的转矩,需操作较 长的时间。

3.万向接头

套筒和扳手之间有一角度时,或操作空间非常小 时,使用万向接头来冲击螺母是极其方便的。

选购附件可能不预先通告而予以更改。

用 途

各种螺栓、螺母的旋紧或旋松。

作 业 之 前

1.电源

确认所使用的电源与工具铭牌上标示的规格是否 相符。

2.电源开关

确认电源开关是否切断。若电源开关接通,则插 头插入电源插座时电动工具将出其不意地立刻转 动,从而招致严重事故。

3.延伸线缆

若作业场所移到离开电源的地点,应使用容量足 够、装合适的延伸线缆,并且要尽可能地短些。

4.边柄的固定

装配在锤盒上的边柄位置可通过旋松边柄来改变 (右侧的螺丝)。工作时,请将边柄旋转至所要 的位置,并拧紧。
