B
Tilt the coolant tank tray slightly to pour the accumulated coolant into the tank.
C
Make the coolant.
To make the coolant, mix the water, additive (ZAW-1000D), and chelating reagent (ZCH-100D) at xed ratios. Use
the included measuring cup for measuring.
1 Water: Mix water and additive in the ratio of “95:5” (water:additive).
There is no need to stir the solution.
The capacity of the coolant tank is approximately 5 L. To ll the tank, use 4,750 ml of water and 250 ml of additive.
2 Water + additive solution: Mix the water + additive solution and chelating reagent in the ratio of
“400:1” (water + additive solution:chelating reagent).
There is no need to stir the solution.
To ll the tank, use 5,000 ml of water + additive solution and 12.5 ml of chelating reagent.
Water: additive = 95:5
* When lling the tank: water = 4,750 ml and additive = 250 ml
Water + additive solution: chelating reagent = 400:1
* When lling the tank: water + additive solution = 5,000 ml and chelating reagent = 12�5 ml
CAUTION
Be sure to use the specied additive.
Additives are e󰀨ective in reducing coolant deterioration and raising the milling e󰀩ciency in order to
maintain product performance. Furthermore, if additives are not used, the coolant may generate an
unpleasant odor.
CAUTION
Be sure to use the specied chelating reagent.
The chelating reagent works to make calcium and similar substances contained in the water inactive,
making it easier to clean o󰀨 milling powder that adheres to the machine and the cutting tool after milling.
Refer to the appropriate safety data sheet (SDS) for the chemical substances used in the additive and chelating
reagent and the safety related to those substances.
To purchase additives, contact your authorized DGSHAPE Corporation dealer or access our website (http://www.
dgshape.com/).
Important
Add an additional 12�5 ml of chelating reagent to the coolant if:
• It is easy for milling waste to adhere to the inside of the machine�
• The milling time exceeds 8 hours, regardless of whether milling waste adheres to the machine�

MEMO
The ratios required to create approximately one liter of coolant are written on the label a󰀩xed close to the coolant tank.
