2. PREPARATION

2-1) Check cooling water

2-2) See that each lubrication oil in filled up.

2-3) Make sure to set the upper side of the material horizontally on working table, with a block on.

2-4) Operator to adjust the vertical UP-DOWN S/W accurately to the working position of the material.

2-5) Cooling water must be sufficiently supplied.

3. OPERATION PROCEDURE

3-1) If KH-305 On S/W is pressed, the spindle motor starts to work, if OFF S/W is pressed, it stops.

3-2) If KH-306 vertical UP-DOWN or OFF S/S is pressed, working of up, down or off.

4. MAINTENANCE

4-1) PERIOD INSPECTION

Period		Details
Daily	1 Time	Supply of lubrication oil with vertical slide way
Weekly	1 Time 2 Times 3 Times	Supply to grease with the parts of bevel gear Supply to lubrication oil with the parts of arm joint Supply to grease with the grease nipples of the main spindle
Quarter	1 Time 2 Times 3 Times	Check the main spindle bearing Check the vertical motor bearing Supply to grease with the grease nipples of the vertical motor.

4-2) MAINTENANCE

4-2-2) The perpendicularity of column and the parallelism of polishing table should be checked in from 15 days to 1 month after the machine is installed, and should be tested every month during six months and screwed the tighten bolts.

4-2-2) The machine is always operated with water and stone particles. So make sure to pay contant attention on lubrication, and to supply lubrication oil frequently to prevent oil shortage.

4-2-3) As the machine is working in the surface of column has rusted or letted stone particles jammed, should be careful about defacement of the vertical motor.
