To change the coolant:
1. Position the coolant nozzle over the back of
the back splash so that it is pointing behind
the lathe.
2. Place the 5-gallon bucket behind the lathe
and under the coolant nozzle. If you are using
the optional hose, connect it to the nozzle
and place it in the bucket. Otherwise, you
may need to have another person hold the
bucket up to the nozzle to prevent coolant
from splashing out.
3. Turn the coolant pump ON and pump the old
fluid out of the reservoir. Turn the pump OFF
immediately after the fluid stops flowing.
Adding Coolant
4. DISCONNECT LATHE FROM POWER!
5. Remove the vented access cover from the
side of the right stand, then slide the tank
out.
6. To enable the remaining fluid to be poured
out in the next step, disconnect the fluid hose
from the pump (see Figure 112).
Note: The pump cord was purposely left long,
so the tank can be removed and dumped out
without disconnecting the wires from the
pump.
7. Pour the remaining coolant into the 5-gallon
bucket and close the lid.
8. Clean all the sludge out of the bottom of the
tank and then flush it clean. Use the second
bucket to hold the waste and make sure to
seal the lid closed when done.
Dispose of the old coolant and swarf accord-
ing to federal, state, and fluid manufacturer's
requirements.
Running the coolant pump longer than
necessary for this procedure without
adequate fluid in the tank may permanently
damage it, which will not be covered under
warranty.
3. Pour coolant into the tank until it is nearly
full.
4. Slide the tank back into the cabinet and
replace the access cover.
Changing Coolant
When you replace the old coolant, take the time
to thoroughly clean out the chip drawer, catch tray,
and fluid tank. The entire job only takes about a
1
⁄2 hour when you are prepared with the proper
materials and tools. Make sure to dispose of old
fluid according to federal, state, and fluid manu-
facturer's requirements.
