3.1 MAINTENANCE

 

 

Routine maintenance 

After using the machine, make sure to turn off the input main power to prevent 
the leakage of the electricity. 

To make sure the function of the machine could work well for a long time, 
please keep clean all around the machine and the switch from the oil pollution. 

To make the machine run normally, the control box, the machine and the table 
should be kept clean all the time. 

Check at any time the lubrication of the reducer to extend the lifetime of the 
machine. 

Check if the cable is damaged or melted for overheat. 

Check the contactor, relay and other connectors are loose or melted. 

Check every limit switch is fixed or loses function. 

Regularly give the machine cleaning and the anti-rust maintenance. 

Regularly change and refill the lubrication of the worm reducer.
