2. Check whether the parts are complete before use, and whether the selected moving gear is consistent with the speed of the bent steel bar diameter machine. Whether the cone engagement gap is appropriate. Whether the fixing wedge is tight and firm.

And check whether the turntable steering is consistent with the direction of the reverse switch. And add lubricating grease according to the regulations. Check whether the insulated grounding wire of electrical equipment is damaged or loose.

And after trial operation, it can be operated only if it is qualified.

3. During operation, one end of the steel bar to be bent should be stabilized in the gap between the turntable and fixed the head, and the other end should be close to the fuselage to fix the head, and press it with one hand.

Fourth, replace the fixed head on the turntable, and then replace it after the operation is stopped.

5. It is strictly forbidden to bend steel bars that exceed the specified diameter of the mechanical brand and the hook used for hoisting lifting rigging. If the steel bar is bent without cold drawing or with rust scale, protective goggles must be worn. When bending non-ordinary steel bars such as low-alloy steel, the maximum limit diameter should be converted according to the provisions of the mechanical name brand.

6. The installation of variable speed gears shall be in accordance with the following provisions:

1. Ordinary steel bars with a diameter of less than 18 mm can be installed with fast gears.

2. Medium-speed gears can be used when the diameter is 18 24 mm.

3. Slow gears must be used for diameters of more than 25 mm.

7. When the turntable is reversed, it must be reversed after the previous steering stops. When toggling the switch, you must wait for the stop in the middle gear to stop, and you must not immediately dial the reverse gear. If the chuck is found to flutter during operation, and the motor heat exceeds the requirements of the famous brand, it should be immediately powered off and stopped for maintenance.
