text: If power was lost, such as when the tank ran out of fuel, the turret could be slowly traversed by hand, assisted by the loader who had an additional wheel, which could manually rotate the turret at a rate of one-half a degree per each revolution of the hand crank (i.e. 20° turret rotation required 40 full cranks of the handwheel, and to turn the turret a full 360° the gunner would be required to crank the handwheel 720 full revolutions).
