5 Movement of controls
51 General
5.1.1 The type, location and method of operation of typical primary controls shall be according to Anncx..A for base machine movements, according to AnnxB for equipment movements, and according to Annex C for attachment movements. Specific requirements for graders are found In Annex I). Specific requirements for dozers are found in AnnezJ. Primary controls for equipment not otherwise specified shall follow the same principles as given by Annex B. Primary controls for attachment not otherwise specified shall follow the same principles as given by Annex C.
5.1.2 The movement of the controls in relation to their neutral position shall be in the same general direction as the machine response, unless the combining of controls or customary usage dictates otherwise (e.g. driving control of machines where the operator’s position Is located on the part of the machine that can swing, such as the upper structure of an excavator).
5.1.3 If a machine is equipped with an alternative operator’s position with duplicated control arrangements, then both sets of controls shall operate in the same manner. When one set of controls is active, the other set shall be Inactive. The active set shall be clearly Identified with a visual Indicator. An exception would be for mechanically connected dual controls (e.g. duplicate steering wheels, duplicated propulsion controls) where all controls are continuously active.
5.1.4 All controls shall return to their neutral position when the operator releases the control, unless the control has a detent or hold position for continuous activation.
5.1.5 For foot-operated controls where the pedal is operated in two directions (treadle pedal), for example, downward motion of the front of the pedal and downward motion of the rear of the pedal, the pedal shall pivot under the operator’s foot and shall remain at rest In the neutral position.
5.1.6 The controls shall he so arranged or deactivated or guarded that they cannot be activated unintentionally — in particular for example, when the operator is getting into or out of the operator’s station according to the manufacturer’s Instructions.
5.1.7 The controls shall be arranged so as not to create a tripping hazard when the operator is getting into or out of the operator’s station according to the manufacturer’s instructions.
5.1.8 For gear/drive/speed selection controls the shifting pattern shall be clearly marked, In particular, the neutral position shall be dearly identified.
5.1.9 The identification .symhols shall he on the controls or next to them. If space limitations dictate, a diagram, clearly visible to the operator, showing the primary controls is acceptable.
5.1.10 GraphIcal symbols shall be In accordance with ISO 6405.1 and ISO 6405-2.
5.2 Multifunction controls
5.2.1 General
In the case of a multifunction control used to control the operations of the base machine, equipment or attachments, either separately or In combination, the following applies In addition to 5.1.
