(5) It is not allowed to cut steel bars whose diameter and strength exceed those specified on the mechanical nameplate and red-hot steel bars. When cutting multiple steel bars at a time, the total cross-sectional area should be within the specified range.

(6) When cutting low-alloy steel, the high-hardness cutter should be replaced, and the cutting diameter should comply with the mechanical nameplate.

(7) When cutting short rebar, the distance between the hand and the cutter should be kept above 150mm. If the grip end is less than 400mm, the end of the steel bar should be pressed or clamped with a sleeve or clamp.

(8) During operation, it is strictly forbidden to directly remove broken ends and debris near the cutter by hand. Non-operators shall not stay around the cutter and the swing zone of the steel bar.
