To change the headstock oil:
1. DISCONNECT LATHE FROM POWER!
2. Remove the end gear cover.
3. Remove the V-belts so that oil does not get
on them, necessitating their replacement
(refer to the V-Belt subsection on Page 79 for
detailed instructions).
4. Remove the fill plug on top of the headstock
to allow the oil to drain more freely.
5. Place a 2 gallon catch pan under the head-
stock drain plug (see Figure 100 on Page
65), then remove the plug with a
5
⁄8" wrench.
6. When the headstock reservoir is empty,
replace the drain plug and clean away any oil
that may have spilled.
7. Fill the headstock reservoir until the oil level
is approximately halfway in the sight glass.
8. Replace and re-tension the V-belts, then
secure the end gear cover before re-connect-
ing the power.
