TS ISO 3767-5

TS ISO 3767-5 addresses the symbols used for operator controls and other displays on manual portable forestry machines. On equipment such as chainsaws and brush saws, a shared symbolic language helps present control functions consistently, making the interface easier to recognise across different manufacturers and product families.

Why symbols matter on portable forestry equipment

On handheld forestry machines, the control layout is usually compact and the controls may directly affect the engine, cutting attachment, locks, or auxiliary functions. In general technical terms, symbols replace text with compact visual cues, which is especially useful in multilingual environments and on equipment where quick recognition matters. This supports clearer identification of what a control does without relying on long written instructions at the point of use.

What this part covers and how it relates to the ISO 3767 series

According to the scope and notes provided, this part standardizes symbols specifically for manual portable forestry machines. The notes also place it within the wider ISO 3767 family: ISO 3767-1 contains common symbols used across multiple agricultural, forestry and powered lawn and garden equipment types, while ISO 3767-2, ISO 3767-3 and ISO 3767-4 address other equipment groupings within the same general subject area. ISO 7000 and IEC 60417 are identified as additional references for internationally standardized symbols that may also be relevant.

In practice, TS ISO 3767-5 is a specialized terminology-and-symbols standard for the visual communication used on portable forestry machines. It belongs to a broader system of harmonised operator-control symbols intended to improve consistency and readability across equipment interfaces.
