Always use non-flammable water based
coolant to avoid explosions when the fluid
comes in contact with hot metal chips from
the milling operation. For the best protection
and use, always follow the coolant manufac-
turer's recommendations for coolant/water
ratios.
NOTICE
Running the coolant pump without adequate
coolant in the reservoir may permanently
damage the coolant system on your mill.
This action is considered abuse and is not
covered by the warranty.
3. if the level of coolant is more than 2" below
the top of the reservoir, add more non-flam-
mable water-based coolant to fill the tank.
4. replace the reservoir screen making sure the
fluid return hose is secured in position.
The coolant reservoir on this mill is designed
to store only coolant. During storage some
fluids grow dangerous microbes, or, due
to the collection of toxic metal chips in the
fluid, the fluid can become a potent and
extremely poisonous solution to humans
and animals.
use the correct personal protection equip-
ment when handling coolant to prevent
infections and poisoning.
Follow Federal, State, and the coolant manu-
facturer's requirements to properly dispose
of used coolant.
