What is ISO 6533 about?
ISO 6533 discusses forestry machinery. ISO 6533 specifies the dimensions and clearances for front handguards 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.
Note: For chain-saws with wrap around handles, ISO 6533 is not applicable to the portion of the front handle to the right (when viewed from the rear) of the top brace.
