To to change the headstock oil:
1. 
  DISCONNECT LATHE FROM POWER!
2.
  Remove the end gear cover, the tank access 
cover, and the oil tank fill cap.
3. 
Remove the headstock oil supply line from 
the check valve (see Figure 100).
4.
   Push the drain hose onto the headstock oil 
supply line. If necessary, use a hose clamp to 
ensure a tight connection.
5.
  Hold the other end of the drain tube in the 
bucket, then turn the master power switch 
ON and reset the STOP button. The oil 
pump will start pumping oil from the tank 
and into the bucket. 
6.
  As soon as you hear a sucking sound from 
the tank or when the oil slows or stops 
flowing out, turn the master power switch 
OFF to stop the pump.
7.
 
Remove the drain hose and re-connect the 
headstock oil supply line to the check valve.
8.
  Place rags under the tank outlet cover to 
catch the residual oil in the tank when 
the cover is removed in the next step (see 
Figure 101).
9.
   Remove the pump suction line from the tank 
outlet cover, remove the three cap screws 
that secure the cover, then carefully remove 
the cover.
10.
  Use mineral spirits and rags to clean the 
inside of the tank. Make sure to soak up any 
excess mineral spirits with dry rags so that 
it does not stay in the tank and contaminate 
the oil.
Tip:
 Consider placing one or two magnets at the 
bottom of the tank to collect any fine metal 
particles. This will make cleaning easier the 
next time around and reduce the amount of 
metal particles that may end up in the oil.
11.
  Re-install the tank outlet cover with a new 
gasket or silicone sealant. 
12.
  Place the funnel in the fill spout and add the 
new oil.
13.
  Re-install the tank fill cap and end gear and 
tank access covers, then test the oil pump 
operation.
