专家解读视频
This International Standard specifies the dimensions and clearances for front hand-guards 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. This International Standard is not applicable to chain-saws with wraparound handles.
