Adding Oil
The oil fill plug is located on top of the headstock,
as shown in Figure 112.
Figure 112. Headstock fill and drain plugs.
To change the headstock oil:
1. DISCONNECT LATHE FROM POWER!
2. Open the end-gear cover.
3. Remove the V-belts so that oil does not get
on them, necessitating their replacement
(refer to Replacing V-Belts on Page 82 for
detailed instructions).
4. Remove the fill plug from the top of the head-
stock.
5. Place a 5-gallon catch pan under the head-
stock drain plug (see Figure 112), then
remove the drain plug with a 24mm wrench.
6. When the headstock reservoir is empty,
replace the drain plug and clean away any
spilled oil.
7. Fill the headstock reservoir until the oil level
is approximately halfway in the sight glass.
8. Replace and re-tension the V-belts (refer to
Replacing V-Belts on Page 81), then close
the end-gear cover before re-connecting the
lathe to power.
Changing Oil
Change the quick-change gearbox oil after the
first 300 hours of use, then after every 1000
hours of use. Place a catch pan under the quick-
change gearbox drain plug (see Figure 113). Use
a 24mm wrench to remove the gearbox fill plug
(see Figure 113), then remove the drain plug with
a 14mm wrench and allow the gearbox reservoir
to empty. Re-install the drain plug and add oil until
the level is approximately halfway in the gearbox
oil sight glass, then re-install the fill plug.
