Place a catch pan under the apron drain plug
shown in Figure 104, loosen the fill plug, then
use a 6mm hex wrench to remove the drain plug
and empty the reservoir.

Drain Plug
Flush the reservoir by pouring a small amount of
clean oil into the fill hole and allowing it to drain
out the bottom.
Replace the drain plug and add oil as previously
described.
One-Shot Oiler
The one-shot oiler shown in Figure 105
lubricates the saddle ways with oil from the
apron reservoir.
To use the one-shot oiler, pull the pump knob out
for two or three seconds and then push it in. The
pump draws oil from the apron reservoir and
then forces it through drilled passages to the way
guides.
Repeat this process while moving the carriage
and cross slide through their full range of
movement to distribute oil along the ways.
Lubricate the ways before and after operating
the lathe. If the lathe is in a moist or dirty
environment, increase the lubrication interval.
Check the apron oil level through the sight glass
before using the one-shot oiler.

Longitudinal Leadscrew
Oil Type ...... Mobil Vactra 2 or ISO 68 Equivalent
Oil Amount ............................................ As Needed
Lubrication Frequency ...................................Daily
Before lubricating the leadscrew, clean it first
with mineral spirits. A stiff brush works well to
help clean out the threads. Make sure to move
the carriage out of the way, so you can clean the
entire length of the leadscrew.
Apply a thin coat of oil along the length of the
leadscrew. Use a stiff brush to make sure the oil
is applied evenly and down into the threads.
Note:
In some environments, abrasive material
can become caught in the leadscrew lubricant
and drawn into the half nut. In this case,
lubricate the leadscrew with a quality dry
lubricant.
