the regulations in Table 3 for further details.

6.2 Every day before work, you should lubricate the machine according to the requirements of the machine for

lubrication. And you should often chec,k the oil level of the spindle box. If the lube drops down below the oil

level glass, you should fill the spindle box with lube up to the same height of the oil lever. But never be

allowed to fill it up, with lube in order to avoid the overflow of lube.

6.3 In use, he chip falling onto the sliding surface should be cleaned out in good time to prevent the chip from

falling down between the sliding surface of the saddle rail on the machine bed, and to prevent it from

damaging those surface. You must clean and wash the four anti-dusting felts attached on both ends of the

saddle at regular intervals in order to keep them having a fine effect of anti-rusting.

6.4 After having done the work every day, you should immediately clean out the chip. And you should wipe all

the parts of the machine, and spread the machine oil on the sliding surface of guide rail and the open

surface of non-working range so as to keep them from rust.
