37、g position. 5.3.2.101 Tilting boiling pans The kettle shall only be tilted by a voluntary action of the operator. This requirement shall be the same when the kettle is tilted back to its working position. When actuators are released in any tilting position of the kettle, it shall remain stationary.
38、In the case of a manual control device, it shall be so designed that the tilting motion is controlled during all of its motion. It shall not be possible to adversely influence the tilting action other than by the intended means. The kettle shall be self balanced or self locking. In the case of power
39、 operated tilting of the kettle, it shall be achieved by a maintained action control device which shall be situated outside the danger zone, and located where the operator can see clearly the movement of the kettle during the tilting. The tilting mechanism shall be self-locking to prevent unintended
40、 movements of the kettle in every position in case of failure of the power. Devices controlling the tilting process shall be clearly marked to show the direction of movement. The control devices shall be located and protected in such a way that they cannot be operated accidentally. For tilting devic
