three drops of oil into the port daily
.
Quick Change Gearbox, see Figure 49
Lubrication for the Gearbox is provided through

Basic Maintenance
Lubrication
Take the time to wipe down and oil your lathe after
use. Do not leave metal chips and cutting fluid on
the ways. We recommend using ISO 68 or a gen
-
eral motor oil unless otherwise specified.
Saddle,
see Figure 47
Apply lubrication to the saddle through the two
ball fittings on the top face of the saddle and
one near the saddle handwheel. Make sure the
oil level is
3
⁄4 full as seen in the through the sight
glass. Change the oil for the first time after one
month of operation, and then at six month inter
-
vals. Use the same oil as in the headstock.
Cross-Slide and Compound,
see Figure 47
These slides are also supplied with ball fittings in
their top surfaces and should be oiled the same
as the saddle.
