当控制器不能正确控制机器时，使用备用系统。 提供备用系统以便能够移动机器或执行操作。 备用系统激活时，监视器将指示。
发动机转速控制
可控制发动机转速。 可通过发动机转速控制开关来控制。 当开关置于兔行位置时，发动机转速将升高。 当开关置于龟行位置时，发动机转速降降低。
泵控制
备用状态期间，泵输出将降低额定输出的 60% 至 80%。 动力换档压力是固定的。 应小心以防止发动机熄火。 机器操作期间，当发动机转速旋钮处于低速位置或发动机的输出明显降低时，会发生此种情况。
回转停车制动
备用状态期间，可能会释放回转停车制动。 但是，当液压油供应停止时，制动激活。 当发动机停机或液压锁杆移至锁止位置时，液压油供应停止。
