safe operation

(1)The working table which receives and feeds the material should be kept level with the lower part of the cutter, the length of the table can be determined according to the length of the processed material. When processing longer steel bars, there should be a special helper, and follow the operator's command, no arbitrary pushing and pulling.

(2) before starting, must check the cutter should be no cracks, tool holder bolt fastening, protective cover firmly. Then turn the pulley by hand, check the gear mesh clearance, adjust the cutter clearance.

(3) after starting, should first air rotation, check the transmission parts and bearing operation is normal, before operation.

(4) machinery does not reach normal speed shall not cut material. Cut off must be used when the cutter, under the part, hold the bar aligned to the blade and quickly sent into the operator should stand on the side of the fixed blade force Pressure on the rebar should prevent the end of the rebar from popping up and injuring people. It is forbidden to use two hands on both sides of the blade to hold the bar leaning over the feed material.

(5) shall not cut the diameter and strength of more than mechanical nameplate provisions of the steel and red-hot steel. A cut off more than one bar, the total cross-sectional area should be within the specified range.

(6) shear low-alloy steel, should be replaced with a high hardness cutter, shear diameter should be consistent with the mechanical nameplate regulations.

(7) cut short material, close to the blade and the distance between the hand blade should be maintained more than 150mm, such as hand grip end less than When 400mm, the short head of the bar should be pressed or clamped firmly with sleeves or clamps.

(8) During operation, it is forbidden to eliminate the broken head and other debris directly by hand, and non-operators are not allowed to stay around the swing of the bar and near the blade. .

(9) When the mechanical operation is found abnormal, abnormal sound or cutter crooked, should be immediately shut down for overhaul. Maintenance must be shut down, cut off the power before proceeding.

(10) hydraulic drive cutter before operation, should check and confirm the hydraulic oil level and motor rotation direction to meet the requirements. After starting, it should be no-load operation, release the open valve, exhaust the air in the hydraulic cylinder, before cutting the bar.

(11) manual hydraulic cutting machine before use, the oil drain valve should be tightened clockwise, after cutting, should be immediately pressed counterclockwise The direction is screwed loose. During operation, the hand should be held steady cutting machine, and wear good insulating gloves.

(12) After operation, cut off the power supply, use a steel brush to eliminate the debris between the cutter, clean and lubricate the whole machine.
