Cleaning Pump System & Changing Oil
The headstock oil pump system must be cleaned
and the oil changed after the break-in period and
then annually (or every six months with hard
service or extreme working conditions).
To clean the oil pump system:
1. DISCONNECT LATHE FROM POWER!
2. Remove the cap from the fill spout shown in
Figure 110.
3. Place at least a 3-gallon drain pan under the
tank and remove the drain plug to empty the
oil into the pan.
4. Clean away any dust, debris, metal shavings,
or grime from the access cover.
5. Using a 4mm hex wrench, remove the four
access cover cap screws, then use the cap
screw in the center as a handle and lift off
the access cover.
6. Put on splash-proof safety glasses, rubber
gloves, and a respirator rated for fumes.
7. Using mineral spirits and rags, wipe down
the inside of the tank to clean it. Make sure
to soak up any excess mineral spirits with a
dry rag, so it does not stay in the tank.

8. After the tank is completely cleaned out,
unthread the screen from the bottom of the
pump suction pipe (see Figure 111), and
remove the screen from the tank.
9. Clean the suction screen thoroughly with
mineral spirits and compressed air.
10. Re-install the suction screen.
Tip: Consider placing one or two magnets at the
bottom of the tank to collect any fine metal
particles generated by the headstock drive
train. This will make cleaning easier the
next time around and ensure that more
metal particles are kept out of the headstock
oil.
11. Re-install the drain plug.
12. Refill the tank with oil (refer to Page 56 for
the recommended type and amount of oil to
use).
13. Replace the fill spout plug.
