A safety device for a drive unit adapted for manual and powered driven movement of a drive shaft. The safety device includes a brake operably associated with the drive shaft for preventing manual and powered driven movement of the drive shaft. It also includes a manual input for releasing the brake and effecting manual driven movement of the drive shaft and a powered input for releasing the brake and effecting powered driven movement of the drive shaft. With this arrangement, the safety device is such that the powered input is operable to disengage the manual input before effecting powered driven movement of the drive shaft.
