7.11 PREVENTIVE MAINTENANCE

To keep the machine in good service conditions, please follow the procedures below to

maintain the machine.

7.11.1 DAILY MAINTENANCE

1. Check to see if the oil quantity in the automatic lubricator is sufficient.

2. Check to see if the cutting fluid quantity in the fluid tank is sufficient.

3. Clean up the machine and working area after finishing the work. Ensure to put a layer

of rust-prevent oil on those exposed sliding surfaces.

4. Turn the power source switch off after job is finished.

5. Release the water accumulated in the air filter cap.

6. Remove chips from the machine every day after job is finished.

7. Check the spindle taper bore after finishing the machining. Clean up the spindle taper

bore with the spindle taper bore cleaner, as illustrated in the following chapter.

8. Stop the machine immediately and find out sources of the problems if any part of the

machine is overheated.

9. Stop the machine immediately and fix the problems before resuming the machine if

any electrical part, such as the connector, switch, electrical socket and electrical wire,
is out of order.

10. Ensure there is no abnormal noise occurs when the machine is running.
