(1) The worktable for feeding and feeding the material should be kept level with the lower part of the cutter, and the length of the worktable 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 obey the instructions of the operator, and do not push or pull arbitrarily.
(2) Before starting the butt welding machine, it must be checked that the cutter should be free of cracks, the bolts of the tool holder are fastened, and the protective cover is firm. Then turn the pulley by hand, check the gear meshing clearance, and adjust the cutter clearance.
(3) After starting, it should be idling first to check that the transmission parts and bearings are running normally before operation.
(4) The material shall not be cut when the machine does not reach the normal speed. When cutting, the middle and lower parts of the cutter must be used, and the steel bar should be grasped and fed quickly to the knife edge. It is strictly forbidden to use both hands to hold the steel bar on both sides of the blade and lean over to feed.
(5) Do not cut steel bars and red-burning steel bars whose diameter and strength exceed those specified on the mechanical nameplate. 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 meet the requirements of the mechanical nameplate.
