Before starting work, the equipment must be inspected according to the "inspection content" of the equipment.

4. The operator must understand the cleaning time and oil change cycle of the oil filter, felt pads, lubricating oil cups, oil felt, and oil line, and clean them according to factory regulations.

5. When parking for more than eight hours before starting the equipment, manual testing of the movement of the workbench or tool holder saddle and the trial operation of each part of the equipment should be carried out first.

6. Before starting work, it is necessary to check the oil storage capacity of the oil tank and inject oil according to the lubrication chart. Check the lubrication status of each part, and do not drive if it is abnormal.

7. It is prohibited to stack tools, accessories, and debris on the equipment, and it is strictly prohibited to tap or step on the surface of the machine tool guide rail and paint.

After installing the gear cutter on the shaft cutter, immediately tighten it with a screw nut.

9. The gear blank to be processed must be firmly installed on the spindle, and corresponding pads should be placed at the bottom to ensure a certain idle stroke of the insertion tool.

13. The screws used for the "T" groove must meet the standards, otherwise they cannot be used.

14. Adjust the insertion distance reasonably according to the tooth width, and ensure that the insertion tool does not collide with the chuck. Set the sound operation range.

15. The gear cutter should not be used when it is worn dull.

When loading and unloading heavy workpieces, they should be handled with care to avoid damaging the working surface.

17. It is prohibited to change the speed of the equipment during movement, and attention should be paid to the positions of the two handles of the gearbox. When one handle is activated, the other handle must be in the middle position, otherwise it cannot be started.

18. It is prohibited for operators to leave or entrust someone to manage the equipment that is in operation.
