1. Quality slitting machine blades must be placed flat when cutting workpieces, and must not be piled up too high or on the aisle. Clean up scraps and waste materials on the construction site to keep the construction site clean and tidy.

2. When cutting into the material, push the handle under the pressure plate to operate. When cutting the short material, press another iron plate tightly, and cut the finger at least 200mm away from the tool. When the pry bar is used on the line, the pry bar outlet should be cut immediately. If the iron plate has moved, it should be quickly plugged with a wooden pillow to avoid injury when the pry bar pops out.

3. The blade should be kept sharp, blunt or damaged, and should be ground or replaced in time. Multiplayer operations must be commanded and coordinated by special personnel. The slitting circle on the quality slitting machine blade is forbidden to cut two materials with different specifications at the same time, and overlapping cutting is not allowed.
