to add oil.

prevent debris from falling into the reservoir
when adding oil.

To change the oil in the reservoir:
1. DISCONNECT LATHE FROM POWER!
2. Open the change gear cover on the left of the
headstock.
3. Remove the reservoir fill plug (see Figure 79).
Note: If you are experiencing difficulty remov-
ing the fill plug, do not remove the drain plug
to drain the reservoir until you can success-
fully remove the fill plug. This way you can still
operate the lathe until the issue is resolved.
4. Hold the drain pan under the reservoir drain
plug, then remove the drain plug shown in
Figure 80, and allow the oil to completely
drain into the pan.
NOTICE
The feed rate gearbox oil must be changed
after the first three months of operation,
then annually after that.
