4.1 Lubrication system
Check all the fitting of lubrication system under normal operation temperature.
If oil leaking is founds, tighten the fittings. Inspect oil level daily.
4.1.1 Replacing headstock oil
It is necessary to replace the oil for a new machine after one month. After first
replacement, it is recommended to replace the oil every
1300 operation
hours.
While replacing the oil, clean the oil tank thoroughly, just adding oil without
replacing, it is a waste of time and money for the new oil will not refresh the old
oil but deteriorating it. The metallic particle and dust in the old oil will form a
layer on the surface which will accelerate the oxidization of oil.
For replacing the lubricant, please refer to Figure 4-1 and follow the steps
below
：
1) The recommended lubricant is
Shell Telus 32 or Mobil DTE#24.
2) Prepare a large container at the front side of the headstock.
3) Turn off the lathe and the spindle. Disconnect the
escape hose from the lubricant tank, and then
connect to the container.
4) Turn on the lathe and the spindle. The old
lubricant will flow into the container instead.
5) Watch out the lubricant level of the lubricant tank
carefully. Turn off the lathe and the spindle,
when the lubricant tank is almost
empty.
6) Remove the plug of drain hole of the lubricant tank.
Drain out all the old lubricant and get the lubricant
tank really scoured. Then put the plug back.
7) Fill the lubricant tank with new lubricant.
8) Turn on the lathe and the spindle. The headstock
will be flushed by new lubricant, and the dirty
lubricant will flow into the container through the escape hose.
