Introduction

GB/T 4269 Symbols for operator control mechanisms and other display devices of agricultural and forestry tractors and machinery, lawn and garden power machinery it is a fundamental and universal standard that guides the application of symbols in agricultural and forestry tractors and machinery, as well as lawn and horticultural power machinery products in my country.

The purpose of this series of standards is to convey to operators the essential human-equipment interactions that can be understood without requiring specialized training or instruction.

The required intuitive graphic information should be provided to ensure that the symbols are clear, consistent, and easy to understand.

GB/T 4269 aims to establish a comprehensive and easy-to-use symbol standard for agricultural and forestry tractors and machinery, as well as lawn and garden power machinery. It is proposed to be implemented by five departments.

Composition.

---Part 1: General Symbols. The purpose is to standardize the operator's control of agricultural and forestry tractors and machinery, as well as lawn and garden power machinery.

The symbols used for display devices and other display devices are standardized and explained for easy reference.

---Part 2: Symbols for Agricultural Tractors and Machinery. The purpose is to standardize the operator controls and...

Other display devices are represented by symbols, with standardized explanations provided for easy reference.

---Part 3: Symbols for Lawn and Garden Power Machinery. The purpose is to standardize the operation of lawn and garden power machinery.

Symbols are used for placement and other display devices, and standardized explanations are provided for easy reference and use.

---Part 4: Symbols for Forestry Machinery. The purpose is to standardize the symbols used for operator controls and other display devices on forestry machinery.

General symbols are provided, along with standardized explanations, to facilitate reference, use, and the development of new symbols.

---Part 5: Operator Control Symbols and Other Markings for Portable Forestry Machinery. The purpose is to standardize the use of portable forestry machinery.

Common symbols used by operators for manipulating devices and other display devices are provided and explained in a standardized manner for easy reference.
