Motor: The bearings used in the motor are
shielded and lubricated for life, therefore, no
lubrication is necessary.
Leadscrew: Be sure to clean and lubricate the
leadscrew. There is also a bearing on the tail
stock end that will require oil.
Headstock Gearbox: The oil in the headstock
should be changed after the first 2 hours of use,
then every 6 months, depending on usage. We
recommend using a light weight, non-deter-
gent oil. Viscosity can range from 10W to 30W
and may include multi-viscosity oil in this same
range.
To remove the oil in the gear box, remove the
change gear directly under the spindle, remove
the cap screw indicated in Figure 71, and place
a can under the drain hole to collect the waste
oil.
