(1) The work surface of the feeding material should be level with the lower part of the cutter, and the length of the work table can be determined according to the length of the processed material. When processing long steel bars, there should be a special person to help, and follow the instructions of the operator, not pushing or pulling arbitrarily.
(2) Before starting, it must be checked that the cutter should be free of cracks, the knife holder bolts are fastened, and the protective cover is firm. Then turn the pulley by hand to check the gear meshing gap and adjust the cutter gap.
(3) After starting, run dry first, check that all transmission parts and bearings are running normally before operation.
(4) No cutting is allowed when the machine does not reach the normal speed. When cutting, you must use the middle and lower parts of the cutter, hold the steel bar and align it quickly with the knife edge. The operator should stand on the side of the fixed blade and press the steel bar forcefully to prevent the end of the steel bar from popping out and hurting people. It is strictly forbidden to hold the steel bar on both sides of the blade with two hands and leaning over to feed the material.
(5) It is forbidden 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 one 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 materials, the distance between the hand close to the blade and the blade should be kept at least 150mm. If the hand grip is less than 400mm, the short end of the steel bar should be pressed or clamped with a sleeve or clamp.
(8) It is strictly forbidden to directly remove broken ends and debris by hand during operation, and non-operators are not allowed to stay around the swing of the steel bar and near the knife edge.
(9) When it is found that the machine is running abnormally, there is abnormal noise or the cutter is skewed, it should be shut down immediately for maintenance. Maintenance must be stopped and can only be carried out after cutting off the power supply.
(10) Before the hydraulic drive cutting machine is operated, check and confirm that the hydraulic oil level and the rotation direction of the motor meet the requirements. After starting, you should run without load, loosen the oil valve, and drain the air in the hydraulic cylinder before you can cut the ribs.
(11) Before using the manual hydraulic cutting machine, the drain valve should be tightened in a clockwise direction. After cutting, it should be loosened in a counterclockwise direction immediately. During the operation, the hand should hold the cutting machine firmly and wear insulating gloves.
(12) After the operation, the power supply should be cut off, the debris between the cutters should be removed with a steel brush, and the whole machine should be cleaned and lubricated.
