1. When installing the inspection or lubrication chuck, be sure to turn off all power to ensure the safety of the operator.

2. Do not operate the switching valve when the spindle rotates. Before the turret head returns to the safe position, do not index the chuck, and do not allow the workpiece or jaw to contact the turret head.

3. The rotation number of the chuck shall be selected as appropriate according to the cutting conditions to prevent the working objects from flying out, and shall not exceed the maximum allowable limit. The maximum spindle speed can be reached only when the jaws are designed, balanced and processed according to the specifications. The heavy-duty unbalanced jaws have a great impact on the maximum speed. The user should pay full attention to the design of the jaws.

4. Before the safety door is closed, do not start the spindle switch to prevent the workpiece or jaw from flying out.

5. Do not exceed the maximum oil pressure of the chuck to avoid damage to the chuck or flying out of the workpiece.

6. The hydraulic station with check valve shall be used to prevent the internal pressure of the oil cylinder from dropping sharply and the working objects from flying out when the power supply is interrupted.

7. Do not change the chuck at will to avoid damage to the chuck. The worn or damaged jaws should be replaced immediately to prevent the workpiece from flying out during operation.

8. Do not drink alcohol or take narcotic drugs before operating the machine.

9. Do not wear gloves or ties when operating the machine.

10. Always use sling or lifting ring when disassembling and assembling chuck.

11. Please do not get caught when clamping the workpiece.

12. Do not knock the chuck to prevent the claw or workpiece from flying out.

13. Regular lubrication shall be carried out to avoid bearing rust or component wear resulting in poor machining accuracy. Regular maintenance shall be carried out for the chuck under the working environment conditions encountered during its use.
