This International Standard 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, this International Standard is not applicable to the portion of the front handle to the right (when viewed from the rear) of the top brace.
