The headstock gearing is lubricated by an oil
bath that distributes the lubricant with the
motion of the gears, much like an automotive
manual transmission.
Checking Oil Level
The headstock reservoir has the proper amount
of oil when the oil level in the sight glass is
approximately halfway. The oil sight glass is
located on the right side of the headstock, as
shown in Figure 99.
The following recommended lubrication
schedules are based on light-to-medium
usage. Keeping in mind that lubrication
helps to protect the value and operation
of the lathe, these lubrication tasks may
need to be performed more frequently than
recommended here, depending on usage.
Failure to follow reasonable lubrication
practices as instructed in this manual could
lead to premature failure of lathe components
and will void the warranty.
Adding Oil
The oil fill plug is located on top of the headstock,
as shown in Figure 100.

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 77
for detailed instructions).
4. Remove the fill plug on top of the headstock
to allow the oil to drain more freely.
5. Place the catch pan under the headstock
drain plug (see Figure 100), then remove
the plug.
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-
connecting the power. Figure 99. Location of headstock oil sight glass.
