Instruction Manual
The filter drawer is situated on the left in the cooling unit
compartment. A nylon sieve filters larger cutting waste particles
from the cooling water. It is recommended to always have the
filter drawer mounted during cutting.
Depending on use, the filter must be checked and emptied
regularly, to ensure its effectiveness. Should the filter get blocked,
an overflow function will prevent flooding, and direct the
unfiltered cooling water into the tank.
Remember to add Struers Additive for Cooling Fluid: One part of
Additive for 33 parts of water.
The concentration of additive should always lie between 2.7 and
3.3%; the pH should be around 9. Replace the cooling water if pH
is 8.0.
To check the concentration of additive, use a refractometer (0-10
Brix, see diagram.). Concentration = 2 x Brix.
Add Struers Additive for Cooling Fluid if the concentration is
lower than 2.7%. Add water if the concentration is higher than
3.3%.
