biological and
poison hazard! use
the correct personal pro-
tection equipment when
handling cutting fluid and
by follow federal, state,
and fluid manufacturer
requirements to properly
dispose of cutting fluid.
A screen keeps large swarf under the bed where
it can be removed during daily cleaning. however,
smaller swarf washes down into the coolant tank
where it is separated from the pump by a wall
inside the reservoir. if this swarf builds up higher
than the wall, then it washes into the pump cham-
ber and clogs the pump.
in addition, cutting fluid eventually becomes ran-
cid or contaminated, which makes it unsuitable for
further use.
checking coolant system
When checking the coolant system, the goal is to
make sure there is enough cutting fluid, the swarf
level in the first chamber is not too high, and the
cutting fluid has not become rancid or contami-
nated.
to check the coolant system:
1. disConneCt lAthe FroM poWer!
2. remove the cover shown in figure 85 from
the lathe stand.

3. inspect the level of cutting fluid inside the
tank. the cutting fluid should be approxi-
mately an inch below the top of the tank.
4. using a flashlight, inspect the level of swarf
inside the first chamber of the coolant tank.
if the swarf level is beyond
3 ⁄
4
the height of
the wall, then the tank must be cleaned (see
figure 86).

5. inspect the quality of the cutting fluid by
smelling it and looking at the clarity of the liq-
uid. Cutting fluid that smells rancid or is very
cloudy should be changed.
cleaning coolant system
1. pump the cutting fluid into a clean container.
When fluid stops coming out of the nozzle,
immediately turn oFF the coolant pump so
you don't burn it up by running it while dry.
2. disConneCt lAthe FroM poWer!
3. remove the cover shown in figure 85.
4. pull the coolant tank out of the stand and
remove the pump from the coolant tank.
5. Flush out the coolant tank and remove all
swarf.
6. if necessary, clean the intake screen on the
pump.
7. re-attach the pump to the coolant tank and
reinstall the coolant tank into the lathe stand.
8. if necessary, fill the coolant tank with new
cutting fluid; otherwise pour the old cutting
fluid back into the coolant tank.
