OS GSO ISO 6533:2025 Scope
This document specifies the dimensions and clearances for front hand-guards and their openings on portable hand-held chain-saws. These dimensions and clearances ensure the necessary safety provided by the hand-guard, which serves as both a shield between the operator's hand and the saw-chain and as an actuator for manually operated chain brakes.
For chain-saws with wrap around handles (see Figure 1), this document is not applicable to the portion of the front handle to the right (when viewed from the rear) of the top brace.
